Leading the Field in Deposit Protection

Leading the Field in Deposit Protection

Testing proves AMSOIL Signature Series 5W-30 Synthetic Motor Oil provides more complete protection against damaging deposits than its competitors.

The push toward smaller, fuel-efficient yet powerful engines has driven the development of several key technologies. Gasoline direct injection (GDI) and turbochargers are now common features of passenger cars and light trucks. By 2020, industry experts predict that nearly every new vehicle will feature GDI technology, and the vast majority will be turbocharged. While these advanced technologies enhance performance, they also present serious challenges to motor oil.

The Turbocharger Trade-Off

Turbochargers push more air into the engine’s combustion chamber, providing better fuel-economy and performance but also creating intense engine temperatures. They often operate above 150,000 rpm on exhaust gases exceeding 1000°F. These extreme conditions cause some motor oils to break down and solidify into harmful deposits.

Vehicle manufacturers have long recommended different service intervals based on “normal” or “severe” driving conditions. Turbocharged vehicles are automatically included in the severe service category due to the extreme heat they generate. Motor oil with unique properties is required to combat the effects of intense temperatures.

Proof of Protection

AMSOIL Signature Series 5W-30 Synthetic Motor Oil was tested against two competing brands to determine its level of protection against deposit formation in high-heat applications.

Test ResultsThe TEOST 33C test (ASTM D6335) is an industry-standard bench test that simulates turbocharger operating conditions. According to the American Society for Testing and Materials (ASTM), it is “designed to predict the high temperature deposit forming tendencies of an engine oil.” To meet the API SN Resource Conserving and ILSAC GF-5 motor oil specifications that are often recommended by vehicle manufacturers, a 5W-30 motor oil must limit total deposit formation to 30 mg or less.

AMSOIL Signature Series 5W-30 Synthetic Motor Oil held the total weight of deposits to 7 mg, well under the 30 mg limit required by the API and ILSAC, while Royal Purple® API 5W-30 and Mobil1® Extended Performance 5W-30 came in just under the limit at 25.4 mg and 28.2 mg respectively. Signature Series 5W-30 Synthetic Motor Oil protects against harmful deposits on turbochargers 4X better than Mobil1® Extended Performance and 3.6X better than Royal Purple® in industry-standard testing*.

Engine Detuning Kills Performance: How to Protect Your Motorcycle

Engine Detuning Kills Performance: How to Protect Your Motorcycle

Some modern motorcycles are equipped with a knock sensor that adjusts timing to compensate for low-octane gasoline and eliminate engine knock. Unfortunately, when timing is adjusted, you may experience...

Rough idle

Lack of throttle response

Many bikers don’t even know this is occurring. Understanding engine knock, also known as detonation or pre-ignition, requires an understanding of octane, which is a standard measure of gasoline performance.

The three most common octane ratings include:

Anti-Knock Index (AKI)

Research Octane Number (RON)

Motor Octane Number (MON)

AKI is the rating most bikers are familiar with. It’s typically displayed on gas pumps as the average of the fuel’s RON and MON. RON, however, is the most common industry rating.

Engine knock can cause piston damage

Gasoline’s RON is generally a few numbers higher than the AKI posted on the gas pump (e.g. 87 octane fuel, or regular pump gas, has a RON of about 91-92). The higher the octane, the more compression the fuel can withstand before igniting. Low-octane gas is susceptible to uncontrolled and early ignition in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, can cause catastrophic piston damage.

Engine knock may be eliminated by using a higher-octane fuel. Alternatively, you can use a fuel additive designed to raise the fuel’s octane number.

Boost Octane and maximize power and efficiency

AMSOIL Motorcycle Octane Boost increases octane up to three numbers, which eliminates knock or ping and maximizes power and efficiency.

New Synthetic DCT Fluid Rounds Out AMSOIL Transmission Fluid Family.

New Synthetic DCT Fluid Rounds Out AMSOIL Transmission Fluid Family.

The concept of two transmissions working in tandem within one vehicle dates back to the 1930s. The dual-clutch transmission (DCT) made its first practical appearance decades later in several 1980s-era race cars. In 2003, Volkswagen’s Golf* Mk4 R32 was the first production vehicle to feature the technology. Today the spectrum of vehicles with DCTs has widened, from the Hyundai Sonata* to the Nissan GT-R*.   

Automatic and Dual-Clutch Transmissions

Traditional automatic transmissions have a defined set of planetary gears that engage based on vehicle speed. The correct gear is selected as the vehicle accelerates and decelerates. DCTs are automatic transmissions based on the architecture of manual transmissions. They consist of two manual transmissions in the same housing.  Most rely on computer-controlled, wet multi-plate clutches and do not require torque converters. DCTs provide more efficient shifts than traditional automatics because as one clutch is engaged the other readies the next gear. Properly maintained and lubricated the system delivers smooth, split-second shifts, the perfect complement to a powerful, high-performance engine. 

While DCTs are capable of seamless shifts, they can suffer from shudder at low-speeds and during sustained acceleration. A transmission fluid that allows too much or too little friction can result in shudder, slipping or clashing. DCT fluid must also maintain the proper viscosity to provide protection during the high-heat operation native to high-performance sports sedans and super cars. 

AMSOIL 100% Synthetic DCT Fluid

AMSOIL 100% Synthetic DCT Fluid is specifically engineered for sophisticated dual-clutch transmissions. Its perfectly balanced frictional properties protect against shudder and clashing to consistently produce fast, smooth shifts. Synthetic DCT Fluid’s exceptional durability provides stability in stop-and-go traffic and excels under intense, high-heat conditions. It promotes stable synchronizer engagements, extending the life of the transmission.

Can I Use Diesel Oil in My Gas Engine?

Can I Use Diesel Oil in My Gas Engine?

Motorists may favor diesel motor oils over their gasoline counterparts for a few different reasons.

Diesel oil is perceived as more “heavy-duty” than gasoline oils

Some motorists desire a higher viscosity, and it may be easier to find a 5W-40 or 15W-40 diesel oil than gasoline oil

Diesel oil typically contains more robust detergency additives than gasoline oils

It is safe to use a diesel oil in your gasoline engine, provided the diesel oil meets the appropriate specifications and viscosity requirements of your engine. For example, if your gas engine calls for a motor oil that meets the API SN specification, you can safely use a diesel oil of the correct viscosity that meets the API SN spec. For the typical gasoline application, however, a diesel oil isn’t required and the more appropriate choice is a quality gasoline motor oil for both performance and value.

Pay attention to oil specifications

The American Petroleum Institute (API) publishes its “C” category of specification for diesel oil (currently CJ-4) and its “S” category for gasoline motor oil (currently SN). It’s common for today’s diesel engine oils to carry both the API CJ-4 and API SN specifications. Though they’re truly designed for diesel applications, they can be used in gasoline applications for motorists who want to use one oil in all applications. If the diesel oil carries both specs, the oil is safe to use in diesel and gasoline applications. If the diesel oil does not carry the “S” category, AMSOIL strongly recommends against using it in gasoline applications.

The correct oil formlation for the application

In the past, motorists may have been told diesel oils were tougher than passenger car oils for a number of reasons, including higher viscosity, improved corrosion protection, higher Total Base Number and more. Diesel oils are often thought to be formulated with special components not available in gasoline motor oils, such as more robust detergency additives to handle the soot inherent to diesel engines. In some motorists’ minds, diesel oils are still analogous to better protection.

While that may have been true in the past, modern oils are formulated for their intended applications. While both diesel and gasoline oils contain many of the same additives to guard against wear, corrosion, foaming and more, they also contain additives designed to manage the byproducts of combustion. Some of those byproducts change, depending on whether the engine runs on gasoline or diesel fuel. If your vehicle uses a gasoline engine, it’s best to use an oil that contains the correct additives to handle the byproducts of gasoline combustion. The same holds if you’re operating a diesel engine.

When to favor diesel oil over gasoline motor oil

If your gasoline engine is heavily modified to put out more horsepower, using a diesel oil can be beneficial. It’s likely modified engines will need a higher viscosity to withstand the increased stress. You can turn to diesel engine oils for those needs or you might want to consider a racing oil, depending on your engine modifications and lubrication requirements.

Many times the engine builder will help provide insight as to what success they have found. Outside of that, if you have a bone-stock gasoline-powered application it’s best to stick with a gasoline motor oil. They are designed for that type of application and have the components required to manage that engine.

Can Your Motorcycle Survive Heat this Extreme?

Can Your Motorcycle Survive Heat this Extreme?

V-Twins Get Hot

Harley-Davidsons* and other bikes with big V-twin engines generate significant heat, especially in low-speed parades, in rally traffic or on long climbs on hot days. Motor oil plays a critical role in cooling these big air-cooled engines, and even more so in low-speed operation with limited wind generated to cool the bike. If the oil can’t withstand the heat, its ability to protect your bike is compromised.

Is your motorcycle protected against extreme heat?

Watch what happens when we push a 2012 Harley Davidson FXDB to 500ºF in our mechanical lab to see how AMSOIL synthetic lubricants protect against extreme heat.

AMSOIL Synthetic Motorcycle Oil Protects in Extreme Heat

To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-and-go driving conditions of a motorcycle rally or parade route.

A 2012 Harley-Davidson FXDB Dyna Street Bob* motorcycle equipped with AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil was subjected to a strenuous low-speed test cycle, with significant idle time broken by short bursts of engine revving and little to no air moving across the cylinders. Like most Harley-Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling

fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The combination of low airflow and inoperative temperature controls allowed the test lab to subject the oil and engine components to intense heat not normally experienced in the real world. Cylinder temperatures reached more than 500°F, and oil temperatures exceeded 300°F – temperatures well into the range where oils begin to break down and often lead to catastrophic failure.

500°F is No Problem

The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear.

Dyno Test Results

Not only did AMSOIL Synthetic V-Twin Motorcycle Oil prevent the engine from overheating and seizing

during the extreme dyno test, it did so without losing chemical integrity or ability to protect vulnerable engine components. See full results here. Synthetic V-Twin Motorcycle Oil provides outstanding protection in even the most compromising and severe high-temperature riding and idling conditions, providing peace of mind that your air-cooled V-twin is protected even in low speeds on hot days.

AMSOIL formulates a full line of products for V-twins, including AMSOIL Synthetic V-Twin Transmission Fluid and AMSOIL Synthetic V-Twin Primary Fluid.

Your bike should never get this hot. If it does, AMSOIL has you covered.

Ask AMSOIL: How Often Should Synthetic Motor Oil be Changed?

Ask AMSOIL: How Often Should Synthetic Motor Oil be Changed?

Most motorists now understand that synthetic motor oil performs better than conventional oil. It delivers improved wear protection, offers better engine cleanliness and lasts longer. Not as well understood, though, is how often you should change synthetic motor oil.

Not long ago, it was common to change conventional oil every 3,000 miles/3 months. The practice originated in the 1960s as a way to time oil changes with the seasons. The quick lube market picked up the idea as a way to keep traffic flowing, touting it as an “insurance policy” for your engine.

Improvements in motor oil performance and engine technology have since rendered that guideline outdated. The advent of electronic oil life monitors struck a first blow. GM introduced its system in 1988, and it’s now on tens of millions of vehicles. The state of California has aggressively campaigned against changing oil every 3,000 miles, calling it wasteful. The final stake in the heart of the 3,000-mile oil change came in 2011 when Jiffy Lube, the face of the quick lube industry, abandoned the practice, advising motorists to follow the guidelines in their vehicle’s owner’s manual.

If synthetic oil performs better, it should last even longer, correct?

The fact is, most oil manufacturers don’t recommend a service interval for their products. They generally advise you to follow the oil-change recommendation in your vehicle’s owner’s manual, likely due to most motorists’ unwillingness to go longer between oil changes than what’s recommended in their owner’s manual. 

Why spend more money on synthetic oil if it doesn’t last longer?

It’s a good idea for the following reasons:

Improved wear protection – Synthetic oils are more durable than conventional oils. They form a stronger protective film between metal components to shield against wear. AMSOIL Signature Series 5W-30 Synthetic Motor Oil, for example, provides 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard*, extending the life of vital components like pistons and cams.

Better ProtectionBetter engine cleanliness – Synthetics’ improved resistance to heat and chemical breakdown helps guard against harmful engine deposits, so your engine remains cleaner, runs more efficiently and lasts longer. AMSOIL Signature Series scored 93 percent better for piston deposits than required to meet the latest API standard.*

Maximum extreme-temp protection – The average operating temperature of a passenger car/light truck engine has risen to 235ºF, and higher under heavy loads. Synthetic motor oils do a better job of withstanding extreme heat, while their improved fluidity in cold weather helps the oil reach components faster at startup for reliable wear protection.

Many vehicle manufacturers now require synthetic oil – Automakers understand synthetic oils help their vehicles deliver improved performance and last longer. That’s why newer Toyota, GM and European vehicles, among others, use synthetic motor oil.

Not only that, but some synthetic oils, such as AMSOIL extended-drain synthetic motor oils, protect so well you can go longer between oil changes if you choose. Many motorists want to follow the guidelines in their vehicle’s owner’s manual. But lots of them still choose AMSOIL products that are capable of extending drains because they simply want maximum protection for their vehicles or the comfort of reserve protection should maintenance be delayed. Others desire the convenience of a once-a-year or twice-a-year oil change.

For these motorists, AMSOIL Signature Series Synthetic Motor Oil is guaranteed for 25,000 miles/12 months (15,000 miles/12 months in severe service). AMSOIL XL Synthetic Motor Oil is guaranteed for 10,000 miles/6 months, or longer where recommended by electronic oil life monitoring systems. They offer an outstanding combination of performance and value.

And, practicing extended drain intervals won’t void new vehicle warranties. The Magnuson-Moss Warranty Act protects you in these situations. Plus, the AMSOIL Limited Warranty provides an extra measure of confidence.

Carry That Weight

Carry That Weight

Many people overstress their vehicles in the summer, pulling trailers, campers or fifth-wheels with boats, sometimes exceeding their rated towing limits. Severe-service conditions and hot summer temperatures place extreme pressure on transmissions and differentials.   

Modern turbo diesel trucks and vehicles with V-10 engines boast more horsepower and torque than their predecessors, subjecting their differentials to increased levels of stress and heat. Gear oils must provide adequate wear protection, while also providing maximum fuel efficiency.

Thermal Runaway

The extreme pressures and temperatures generated by modern vehicles can lead to a serious condition known as thermal runaway. As temperatures in the differential climb upward, gear lubricants lose viscosity and load-carrying capacity. When extreme loads break the lubricant film, metal-to-metal contact occurs, increasing friction and heat. This increased friction and heat, in turn, results in further viscosity loss, which further increases friction and heat. As heat spirals upward, viscosity spirals downward. Thermal runaway is a vicious cycle that leads to irreparable equipment damage and ultimately catastrophic gear and bearing failure.

The AMSOIL “Tow Package”

AMSOIL Severe Gear® Synthetic Gear Lube (SVG, SVT, SVO) and Signature Series Synthetic Automatic Transmission Fluid (ATF, ATL) provide maximum protection in demanding environments such as towing, hauling and commercial use, providing increased lubricant film protection and reduced wear at elevated temperatures.

Field Proven

Signature Series Synthetic Fuel-Efficient ATF was submitted for a field trial at an independent test facility to prove its ability to protect transmissions in the severe, high-heat environment generated in real-world towing scenarios.

A loaded trailer was towed on real highways and city streets throughout the trial. Signature Series ATF handled the punishment with ease. Throughout 115,000 miles in severe service – nearly 4x the manufacturer recommended severe-service drain interval – Signature Series ATF delivered outstanding protection for gears and clutches and maintained smooth shifts.

Troubleshooting a String Trimmer that has Lost Power

Troubleshooting a String Trimmer that has Lost Power

Check the Age of the Fuel

Today’s ethanol-containing gasoline can break down in relatively short time periods. If your blended fuel supply is more than two or three weeks old, blend a new batch of fuel.

Check Air Filter Condition

A clogged air filter prevents the engine from receiving sufficient air to operate properly. Before removing the air filter, brush away loose debris from around the filter cover and filter element. Tap the filter on a tabletop or the palm of your hand to dislodge any dirt or debris. If you use compressed air, make sure you direct air through the filter from the inside to avoid lodging debris deeper in the filter. Avoid washing the filter as this can collapse its micro-fine structure. If cleaning doesn’t remove debris, replace the filter with the appropriate part recommended by the trimmer manufacturer.

Check the Spark Plug

Spark plug fouling occurs when oil, carbon or other foreign substances coat the tip of the plug and interfere with normal firing. Too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will eventually cause spark plug fouling. Replace the spark plug with a new one recommended by the trimmer manufacturer.

If a new plug is not immediately available, remove the plug and clean all carbon and oil deposits from the plug tip. Set the gap according to the manufacturer’s recommendations and reinstall the plug.

Clean the Exhaust Spark Arrestor Screen

On many trimmers, a small screen covers the exhaust outlet and prevents sparks from exiting the muffler and potentially starting a wildfire. For this reason, trimmers should not be operated if the screen is missing, punctured or disintegrating.

As with plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gas flow, which leads to power loss. To fix the problem, remove the spark arrestor screen and inspect it for plugging. If plugged, either replace it with the appropriate part recommended by the trimmer manufacturer or clean it.

To clean the spark arrestor screen, spray it with AMSOIL Power Foam® to soften the deposits before cleaning the screen with an abrasive pad. Reinstall the screen and test the trimmer. 

If these attempts to restore power fail, take the trimmer to your servicing dealer.

Use High-Quality Oil to Help Avoid Power Loss

Using a high-quality two-stroke oil with excellent detergency can help avoid many of the problems listed here. Two-stroke oils that burn cleanly help reduce plug fouling and spark arrestor screen deposits. AMSOIL SABER® Professional Synthetic 2-Stroke Oil withstands high heat and stress to protect handheld equipment engines against wear and harmful deposits. It can be mixed at conventional mix ratios (32:1, 40:1, 50:1) or the SABER Ratio™ (80:1, 100:1), offering the convenience of one mix ratio for all applications.

How A Motorcycle Wet Clutch Works

How A Motorcycle Wet Clutch Works

Wet clutches are widely used in motorcycles and dirt bikes. The term simply means the clutch is lubricated with oil, as opposed to a dry clutch. A wet clutch typically lasts longer and is more forgiving to operate than a dry clutch.

Frictional Performance Vital

As shown in the images, the clutch connects the engine and transmission via a series of alternating friction and steel plates. Friction plays a big role in proper clutch operation.

To illustrate, imagine sitting aboard a motorcycle or dirt bike with the clutch lever activated, idling at a red light or in a starting gate. The friction and steel plates are separated, allowing the bike to run without moving. The light turns green or the gate drops. As you let out the clutch lever, the plates squeeze together. The transition from the friction and steel plates spinning independently to becoming locked together is an example of dynamic friction. Once the plates are locked together and spinning in unison, they’re subject to the principles of static friction.

Oil Chemistry Important

Motor oil plays a vital role in both areas. The formulation influences the dynamic friction you experience, which is best thought of as clutch feel. Oils with incorrect frictional properties can result in inconsistent or “loose” clutch feel. This negatively affects your ability to confidently pull away from a red light without the bike cutting out, or start quickly and grab the holeshot in a race. The oil also contributes to the holding power, or static friction, between the plates once the clutch lever has been let all the way out and you’re riding. Oils with incorrect frictional properties can allow the plates to slip in some circumstances, which you’ll feel as lost power to the ground. A powerful V-twin riding up a hill, for example, can generate sufficient load to cause the clutch plates to slip and the bike to surge.

The oil’s additive chemistry has the greatest effect on performance. Friction modifiers, added to some passenger car/light truck motor oils to maximize fuel economy, can decrease the coefficient of friction within the clutch pack and result in excessive slippage. Extreme-pressure additives, commonly used in gear lubes to protect against shock loads and intense pressures, can cause excessive clutch slippage and related damage.

The key is to use a lubricant specifically formulated for wet clutches. AMSOIL Synthetic V-Twin Motorcycle Oil, Synthetic Metric Motorcycle Oil, Synthetic Dirt Bike Oil and Synthetic Dirt Bike Transmission Fluid contain no friction modifiers or extreme-pressure additives. They’re dialed-in with the correct frictional properties to promote smooth shifts and consistent clutch feel while guarding against wear for long clutch life.

Revamped AMSOIL Marine Product Line Keeps You On The Water

 Revamped AMSOIL Marine Product Line Keeps You On The Water

Most anglers work full-time and have precious little time for fishing. To maximize their time on the water, they need lubricants that protect their motors from wear despite challenging operating conditions.

Much like automotive engines, marine motors are becoming more advanced and tougher on oil. Four-stroke motors are becoming lighter and produce more low-end torque than before. They’ve largely closed the performance gap on two-stroke motors. In fact, sales of four-stroke motors are on the rise, while two-stroke sales have declined.

Demanding Operating Conditions

Marine motors are characterized by high-rpm operation that can shear the molecular structure of oil and reduce its ability to protect against wear. On average, a marine motor propelling a boat 30 mph operates at 5,000 rpm,

while an automotive engine at 60 mph operates around 2,000 rpm. The added heat and stress invite wear and deposits. Heavy deposits can cause piston rings to stick. Stuck rings lead to compression loss, which reduces power. Stuck rings can also lead to catastrophic piston scuffing.

The marine operating environment creates additional challenges for oil. Marine motors are constantly exposed to humid air. The moisture the motor ingests increases the likelihood of corrosion compared to automotive engines. Water-cooled marine motors also run at lower temperatures than air-cooled engines, so moisture in the oil doesn’t evaporate as readily. Plus, when the motor is shut down for the day, moist air continues to enter the engine as it cools, increasing the risk for corrosion, especially if the oil doesn’t contain anti-corrosion inhibitors.

Marine-Specific Four-Stroke Formulations

AMSOIL 10W-30 and 10W-40 Synthetic Marine Engine Oil and new AMSOIL 25W-40 Synthetic-Blend Marine Engine Oil are shear-stable formulations that deliver maximum wear protection in four-stroke marine applications. They are formulated with advanced additives to guard against corrosion common to marine environments.

Marine-Specific Two-Stroke Formulations

AMSOIL synthetic two-stoke marine oils provide the same great benefits as always, including outstanding wear protection and low smoke. AMSOIL HP Marine® Synthetic 2-Stroke Oil is excellent in modern direct-fuel-injected (DFI) motors that generate increased heat and friction compared to their predecessors. It provides increased lubricity for reduced wear during normal and lean-mix operation. In field testing, HP Marine completely prevented piston skirt and cylinder bore scuffing (see http://www.amsoil.com/proof for details.)

AMSOIL Synthetic 2-Stroke Injector Oil protects against wear and piston scuffing while providing the added benefit of year-round use as a snowmobile oil.

For pre-mix applications, AMSOIL Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil contains a heavy dose of low-temperature dispersant additives that excel at reducing varnish, carbon and deposit formation in water-cooled motors. Its low-smoke, low-odor, low-toxicity properties produce fewer emissions at 100:1 mix ratios than oils mixed at 50:1, benefitting operators and the environment.

AMSOIL Synthetic Marine Gear Lube protects lower units from wear, even when contaminated with up to 10 percent water.

Why Synthetic Blend?

AMSOIL 25W-40 Synthetic-Blend Marine Engine Oil is formulated specifically for Mercury* motors that encourage the use of synthetic-blend oil.

Prepare Your Bike for Summer Riding

Prepare Your Bike for Summer Riding

The complete line of AMSOIL motorcycle products ensures your bike is ready to hit the road.

Bikers of all stripes are gearing up for another season of motorcycle rallies and summer road trips. Whether you’re into V-twins or metric bikes, AMSOIL synthetic motorcycle oils are dialed-in to meet the unique demands of your bike.

V-Twin Motorcycles

Powerful, hot-running V-twins generate intense heat, especially in slow-moving rally or parade traffic. Air-cooled bikes rely on a steady flow of air over the cooling fins to conduct heat away. Stop-and-go driving and periods of idling on hot summer days can quickly cause the engine temperature to skyrocket. If a motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised.

In addition, the intense heat and mechanical action inside a motorcycle engine can cause motorcycle oils to lose viscosity, or shear. Bikes that share a sump between the engine and transmission are especially prone to viscosity loss due to shear. AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable and does not thin from mechanical activity. It does an excellent job protecting your expensive bike against wear.

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil has been updated with labels and packaging that bring it in line with the rest of the V-Twin line introduced last year. SAE 60 Synthetic V-Twin Motorcycle Oil labels and packaging will follow in May. Together they complete the AMSOIL V-twin product line in time for the start of motorcycle season. New labels will be available when current inventory is depleted. 

AMSOIL Synthetic V-Twin Motorcycle Oil delivers excellent performance in transmissions and primary chaincases, offering the convenience of one lubricant for all three areas of your bike. Some bikers, however, prefer lubricants formulated specifically for their transmission or chaincase. AMSOIL Synthetic V-Twin Transmission Fluid and Synthetic V-Twin Primary Fluid offer excellent performance in these situations.

Metric Motorcycles

The metric motorcycle market is divided into three segments.

Metric Sport Bikes

Metric Cruisers

Metric Touring

Sport

Sport bikes (crotch rockets) need wet-clutch-compatible lubricants that deliver consistent shift performance. The high speeds and rpm at which riders travel can cause oil to foam, requiring lubricants that offer superior foam control.

AMSOIL Synthetic Metric Motorcycle Oil helps you push your bike to the edge. Its advanced synthetic technology maximizes engine responsiveness while delivering excellent wet-clutch compatibility for smooth shifts. By controlling foam, it helps you confidently push your engine toward the red line for maximum speed, acceleration and cornering ability.

Cruiser

Like sport bikes, metric cruisers are defined by engine responsiveness, power and speed. Superior handling, easy shifting and reliability are also important traits.

AMSOIL Synthetic Metric Motorcycle Oil delivers smooth, confident shifts and excellent wear protection. By resisting extreme heat and helping cool hot engines, it promotes peace of mind and confidence.

Touring

Metric touring bikes typically accentuate comfort, luxury and the adventure associated with long, cross-country trips. AMSOIL Synthetic Metric Motorcycle Oil enhances reliability by delivering superior engine protection. Its outstanding performance provides the security of knowing your bike is going to provide trouble-free operation mile after mile. It extends drain intervals up to twice the bike manufacturer’s recommendations, allowing you to enjoy peace of mind when far away from home and unable to stop for an oil change. AMSOIL Synthetic Metric Motorcycle Oil’s wet-clutch compatibility enables smooth shifts for a comfortable ride.

No matter the bike, AMSOIL has you covered. 

Z-ROD® Keeps Classic Vehicles Street-Ready

Z-ROD® Keeps Classic Vehicles Street-Ready

AMSOIL Z-ROD® Synthetic Motor Oil protects engines on the highway and in the garage.

Making the transition from storage to the street can be an anxious time for classic car owners. Even after extensive preparations, doubts may linger whether a prized vehicle has been effectively protected during a period of inactivity. Many owners now look to modern technology to keep vintage hot rods and muscle cars performing at a high level on the street and fully protected during storage.     

Protecting engines designed decades ago- and engines modified for increased performance- can be challenging. From flat-tappet cams and splash-lubricated components to the toll of periodic storage, unique issues must be addressed.

Flat-Tappet Cams and ZDDP

The design of flat-tappet cams makes them especially vulnerable to wear. As the name indicates, the tappet- or lifter - is flat. During operation the surface of the cam lobe slides rapidly over the surface of the tappet, producing high friction and temperatures. The camshaft and lifters are responsible for triggering the precisely tuned movements of the valve train. Here, the use of anti-wear additives becomes crucial.

Zinc dialkyldithiophosphate (ZDDP) is a commonly used motor oil additive that provides anti-wear protection and minimizes lubricant breakdown. ZDDP also exhibits mild extreme-pressure protection. As temperatures in an engine rise, ZDDP decomposes, and the resulting chemistry protects critical metal surfaces. 

Without the protective film barrier provided by ZDDP, the cams and lifters wear from the force of operation, negatively affecting cam and valve operation. Because most V-8 engines of the muscle car era came standard with flat-tappet cams, the problem is prevalent to classic-car and hot rod owners.

In these applications, modern oils, such as AMSOIL synthetic motor oils, are capable of providing adequate wear protection after the engine has been broken in. But due to variables like severity of service and level of modification, AMSOIL primarily recommends high-ZDDP oils in these applications, such as Z-ROD® Synthetic Motor Oil. When breaking in a rebuilt or high-performance engine, AMSOIL recommends AMSOIL Break-In Oil, which contains high levels of ZDDP for added protection. 

Rust and Corrosion

Moisture can be as devastating an engine contaminant as dirt or sludge. Vehicles subjected to long-term storage are especially vulnerable to humidity-driven rust and corrosion. AMSOIL Z-ROD® Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors to ensure maximum protection during storage.

AMSOIL Dirt Bike Products Maximize Performance of Bike and Rider

AMSOIL Dirt Bike Products Maximize Performance of Bike and Rider

Whether you ride to take the checkered flag or conquer the trails near home, AMSOIL has you covered.

Most dirt bike riders have one goal in mind when they hit the track or trail: ride faster and more effectively. Clutch performance goes a long toward ensuring you get out front and stay out front. Clutch slippage or inconsistent clutch feel can lead to poor starts out of the gate, while maneuvering around obstacles on the trail increases the opportunity for clutch slippage if low-quality lubricants are used.

Consistent clutch feel important

AMSOIL Synthetic Dirt Bike Oil’s superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when navigating the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading manufacturer’s oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. AMSOIL Synthetic Dirt Bike Oil’s superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions. It also delivers superior wear protection for engine and clutch components.

Some riders, however, prefer a dedicated transmission fluid instead of a multi-purpose motor oil. For them, AMSOIL Synthetic Dirt Bike Transmission Fluid features a wet-clutch-compatible formulation designed to prevent clutch slippage and deliver consistent, confident clutch feel. It helps you ride smoother and faster for maximum performance. It also provides excellent wear protection for gears and clutch plates, reducing time and money spent on maintenance.

Clutch Plates

Don’t overlook chain and fuel maintenance

Although easy to overlook, the chain is another important area to maintain. In order to ensure optimum performance and life, dirt bike chains require premium lubrication and protection against dirt, mud, water and constant stress. AMSOIL Chain Lube doesn’t fling off, helping you avoid the hassles of frequent reapplication and the stresses of worrying about chain durability.

Degraded fuel presents major problems for dirt bike engines. It can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons, causing pre-ignition, rough idling and poor throttle response. AMSOIL Quickshot® is formulated to thoroughly clean and restore peak performance in dirt-bike fuel systems. Its revolutionary technology addresses problems associated with ethanol, water and dirty pump gas.

Shift to AMSOIL Protection

Shift to AMSOIL Protection

AMSOIL Signature Series Synthetic Automatic Transmission Fluid has been proven in the field to deliver reserve protection against heat and wear.

The demands on today’s automatic transmissions have multiplied. Excessive idling, extreme temperatures and hauling heavy loads all pose threats to a transmission’s longevity. Work vehicles are consistently used in these severe-service conditions but operators are often unaware of the toll it’s taking on their transmissions.

Automatic transmissions have evolved into an intricate mix of gears, clutch packs and narrow oil passageways that require a steady supply of lubrication. They have become smaller yet must withstand higher horsepower and torque. Transmission fluid must act as a lubricant protecting against intense heat and shearing, and also as a hydraulic fluid to enable shifting. Neglecting this vital fluid leads to extreme heat stress, erratic shifts and catastrophic wear. Ultimately, a time-consuming and costly repair or a complete transmission replacement become the only options.

The AMSOIL Advantage

AMSOIL Signature Series Synthetic Automatic Transmission Fluid is specifically formulated to withstand the rigors of daily towing, elevated temperatures and challenging terrain. Its wax-free formulation remains fluid in sub-zero temperatures and ensures excellent shift response, energy efficiency and warm-up times. It provides reserve protection during heavy use and even abuse.

The Proof

F-150 Towing Field Study

The consistent hauling of boats, campers, equipment or supplies can tax a transmission to the point of failure. We submitted Signature Series Synthetic Fuel-Efficient ATF for a field trial at an independent test facility to prove its ability to protect transmissions in the severe, high-heat environment generated in real-world towing scenarios.

A loaded trailer was towed on real highways and streets throughout the trial. Signature Series Synthetic ATF handled the punishment with ease. Throughout 115,000 miles in severe-service it delivered outstanding protection for gears and clutches and maintained smooth shifts.

Oil Filtration Basics

Oil Filtration Basics

Oil filters play a major role in the performance and longevity of an engine by removing contaminants and promoting proper oil flow.

Modern engines introduce more contaminants into oil than their predecessors. To compound the issue, oil sumps are shrinking, leaving fewer detergents and dispersants to help fight the by-products of the internal combustion process. An oil filter’s capacity must improve to contend with the additional contaminants. Capacity refers to the amount of contaminants a filter can hold while still remaining effective.

To understand the significance of capacity, it’s helpful to know the basics of oil filtration. Clean oil is vital to keeping engines running properly. The oil filter must remove contaminants introduced into the oil and prevent them from reaching sensitive engine parts without restricting normal oil flow. Internal sources of contamination include wear products from the rubbing surfaces of the engine, and degradation of the oil itself. To provide top-notch performance, a filter must be constructed with the optimum balance of capacity, efficiency, flow and  durability.

Advanced Media Technology

AMSOIL Ea Oil Filters are engineered using full-synthetic media that features smaller fibers compared to the cellulose and blended media found in other filters. The smaller fibers have a controlled size and shape, providing greater efficiency, capacity and durability. The media in Ea Oil Filters provides up to two times greater capacity than competing filter brands.

Absolute Efficiency

Efficiency describes the filter’s ability to capture contaminants. The more efficient a filter, the more contaminants it re-moves from the oil. Manufacturers typically report their filters’ efficiencies as the percentage of contaminants 20 microns and larger removed from oil. Filters using traditional media are often only 40 to 80 percent efficient at 20 microns.

In extensive testing, the full line of AMSOIL Ea Oil Filters achieves a near- perfect absolute efficiency rating of 98.7 per-cent at 20 microns, making each filter among the most efficient available for autos/light trucks.

Improved Flow

Flow is restricted as the spacing in the filter media is made smaller to provide greater efficiency. The unique design and full-synthetic media in AMSOIL Ea Oil Filters allow decreased space between fibers without restricting  flow. This provides exceptional cold-start performance and ensures proper levels of lubrication throughout the engine.

Durable Construction

Over the service life of a cellulose filter, hot oil degrades the resins that bind the media. Ea Oil Filters’ full-synthetic media is backed with a wire screen that is pleated with the media for superior strength. Ea Oil Filters are constructed with HNBR nitrite gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting premium-grade silicone anti- drain valve.

AMSOIL DOMINATOR® COOLANT BOOST REFORMULATED WITH LATEST TECHNOLOGY

AMSOIL DOMINATOR® COOLANT BOOST REFORMULATED WITH LATEST TECHNOLOGY


Improved compatibility, faster engine warm-up times and reduced engine temperatures highlight the new formulation.

Dominator Coolant Boost has been reformulated with the latest organic-acid technology. The new technology adds to the benefits provided by the previous formulation, including reduced engine temperatures by up to 25ºF (previously 19ºF) in straight-water applications and up to 54 percent faster engine warm-up times (previously 45 percent). Organic acids are more robust and longer-lasting than inorganic acids, offering excellent resistance to scaling, drop-out and corrosion. They also contribute to improved compatibility; the new Dominator Coolant Boost formulation can be mixed with soft, tap and distilled water, in addition to any brand of antifreeze. Users will also notice the product is now orange in color.

While racers derive the most value from Dominator Coolant Boost, it provides benefits for everyday motorists, too. 

Helps Racers Win

Racers value reduced engine temperatures the most since excessive heat robs engines of efficiency and power. Racers look for any way to reduce engine temperatures to gain an advantage over their competitors. Dominator Coolant Boost is perfect for racing applications; it reduces engine temperatures up to 25ºF in straight-water applications.

Straight water, however, invites damaging radiator and water-pump corrosion. Dominator Coolant Boost delivers outstanding corrosion protection. In industry standard testing (ASTM D1384 and ASTM D2570), Dominator Coolant Boost limited corrosion to the six metals most commonly found in cooling systems (copper, solder, brass, steel, cast iron and cast aluminum), easily passing both tests. 

Helps Motorists Warm Car Faster

Motorists who live in cold climates value faster engine warm-up times the most. Dominator Coolant Boost features proprietary tiered-surfactant technology that results in up to 54 percent faster engine warm-up times, resulting in a more comfortable vehicle on cold winter mornings.


A surfactant reduces the surface tension of water and antifreeze, allowing closer contact with metal parts. This closer contact increases the coolant’s efficiency in transferring heat away from hot engine parts and out through the radiator and fan. Many leading coolant additives contain only one surfactant, limiting their temperature ranges and effectiveness. Dominator Coolant Boost uses three surfactants, each designed to operate in a different temperature range to increase liquid-to-metal contact from the time the vehicle starts to the time it reaches operating temperature.

Rust & Corrosion Attack Vehicles

Rust & Corrosion Attack Vehicles

Most motor oils only provide minimal protection against damaging engine rust and corrosion.

The effects of rust and corrosion are easy to see on the exterior of vehicles and equipment. However, they can also form on the inside of your engine if you’re not using a properly formulated motor oil.

The problem is especially problematic in engines used in applications that sit idle for extended periods, including the following.

Boats

Motorcycles

Lawnmowers

Classic cars

Snowblowers

Despite what most people assume, motor oils have no natural ability to protect against rust or corrosion. Instead, special rust and corrosion inhibitors must be added to the formulation to provide the required protection, and some oils simply don’t contain the correct additives in the correct concentration.

Idleness equals no protection

During engine operation, a layer of oil coats engine parts and the crankcase walls. The lubricant film protects against rust and corrosion as long as it remains in place. However, after you shut down the motor for the day, gravity draws the oil back down into the oil sump, leaving components unprotected. The longer the engine sits, the more rust and corrosion can form.

Once rust begins to form, it doesn’t stop. It can slowly spread to the crankshaft journals, cylinder wall, piston rings and other areas. It acts like sandpaper and scours metal surfaces until engine failure eventually results. It can also prevent the piston rings from forming a good seal against the cylinder wall, which reduces compression and leads to power loss.

Aluminum parts may not rust, but they can corrode, especially in marine motors constantly exposed to humid air. If the valves aren’t completely sealed when the engine shuts down, damp air infiltrates the combustion chamber and causes aluminum pistons to corrode. Corrosion on the piston crown invites conditions that can lead to pre-ignition, a phenomenon where the fuel/air mixture ignites sporadically and potentially causes catastrophic engine failure.  

Passenger car motor oils don’t cut it

It’s vital to use a motor oil formulated with anti-rust/anti-corrosion additives in vehicles and equipment that sit idle for long periods. These additives form a resilient protective layer that clings to engine parts for maximum protection. Since passenger cars/trucks are typically driven daily, rust and corrosion largely isn’t a concern. As such, most passenger car motor oils don’t contain sufficient rust and corrosion inhibitors for engines used periodically. Instead, use a motor oil specifically formulated for your application.

AMSOIL Synthetic Motorcycle Oil, AMSOIL marine engine oils, AMSOIL Z-ROD® Synthetic Motor Oil and AMSOIL Formula 4-Stroke® Synthetic Small Engine Oil contain robust rust and corrosion inhibitors. They deliver outstanding performance for your engines when you’re driving, and superior rust and corrosion protection when they sit idle.

AMSOIL Grease Saves Commercial Account Big Money

AMSOIL Grease Saves Commercial Account Big Money

A manufacturing company in Illinois is saving big money using AMSOIL grease.

St. Louis Prestress in Glen Carbon, Ill. is a prestress/precast manufacturer of concrete pieces used to build various buildings such as parking garages, warehouses and schools.

The manufacturing process includes the use of extruder machines for making hollow core panels used for building roofs and floors.

Bryan Ebersohl, the maintenance supervisor and batch plant foreman at St. Louis Prestress, was looking for a way to save money when he decided to try AMSOIL Synthetic Multi-Purpose Grease NLGI #2 on the expensive bearings of the huge machines.

“These machines have vibrating augers that run about 16,500 rpms,” Ebersohl said. “I have tried lots of different grease trying to get a little longer life out of these bearings because they are very expensive. I used to change bearings about every 100 hours, because the grease would not hold up.”

The machines have 64 bearings each, and the company has three of the extruders. The bearings cost between $75 and $180 each, Ebersohl said.

The company is a commercial account for Dealer Larry Goss.

About four years ago, Ebersohl started using AMSOIL Synthetic Multi-Purpose Grease NLGI #2 on the bearings.

“Since I started using the AMSOIL grease I checked the bearings at 100 hours, 200 hours, 300 hours, all the way to 600 hours,” Ebersohl said. “This grease has saved our company thousands of dollars on bearings.

“Using this grease I haven’t had to change any bearings. I just clean them and reuse them. I used to take these machines apart at least every 100 hours to clean and usually replace bearings, now I run these machines up to 500 hours before cleaning the bearings and regreasing them.”

Spring Maintenance Should Include More than an Oil Change

Spring Maintenance Should Include More than an Oil Change

Neglecting maintenance creates problems down the road

Spring Maintenance Should Include More than an Oil Change

Paying attention to your vehicle’s recommended maintenance schedule extends engine life and prevents costly repairs. As warmer weather approaches, many people get under the hood for an oil change.

While motor oil is often the only regular vehicle maintenance performed, multiple other fluids and components require attention for vehicles to perform at a high-level.

Transmission Fluid

Transmission fluid must act as a lubricant protecting against intense heat and shearing, and also as a hydraulic fluid to enable shifting. Neglecting this vital fluid leads to heat stress, erratic shifts and catastrophic wear. AMSOIL Signature Series Synthetic Automatic Transmission Fluid delivers superior friction durability and reserve protection against extreme heat and wear.

Gear Lube

Gear lube helps prevent “thermal runaway” — a phenomenon caused by a lubricant's inability to control friction and increased heat under high-stress conditions. AMSOIL synthetic gear lube inhibits rapid lubricant degradation and component damage. It offers superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.

Coolant 

Antifreeze/coolant protects cylinder heads and water pumps from metallic corrosion and prevents engines from over-heating and freezing. AMSOIL Antifreeze & Coolant inhibits the scaling issues common in cooling systems and effectively shields cylinder liners from cavitation erosion and corrosion pitting.

Power Steering Fluid

This often over-looked fluid helps transmit the power in the power steering system while protecting components from wear and heat stress. Like all lubricants, it accumulates wear material and debris. Replenishing your power steering system with a quality power steering fluid can save you from the hassle of an expensive and labor intensive power steering pump replacement. AMSOIL Synthetic Power Steering Fluid synthetic chemistry delivers excellent lubricity and friction-reduction properties. It resists the effects of contaminants and temperature extremes to provide long, trouble-free service. 

Brake Fluid

Transferring force into pressure, this fluid literally helps you put the brakes on.   Over time, water can work its way into brake lines and corrode brake parts, lines and seals. Maintaining your brake fluid helps contain water contamination and prevent system failure. AMSOIL Synthetic Brake Fluid keeps water in suspension, slowing its corroding effects. It lubricates braking components and maintains a stable viscosity over a wide temperature range to deliver safe, consistent braking.

Review the maintenance schedule in your owner’s manual to ensure all the components of your vehicle that need fresh fluid are up to date. 

Use High-Quality Antifreeze to Guard Against Cooling-System Problems

Use High-Quality Antifreeze to Guard Against Cooling-System Problems

Antifreeze/coolant is critical to proper engine operation, but it’s often overlooked when performing preventative maintenance. One reason is many motorists simply don’t understand the importance of a properly functioning cooling system to maximum engine performance. Another reason is the confusion surrounding the different “colors” of coolants on the market and the problems that result from mixing incompatible coolants. 

What is Antifreeze/Coolant?

Like motor oil, antifreeze/coolant consists of a base component mixed with additives. The base, either ethylene glycol (EG) or propylene glycol (PG), helps lower the freeze point of water to protect the engine during winter while raising the boiling point of water to help prevent engine overheating in the summer.

Ethylene Glycol is the more common of the two. Compared to PG at a similar mix ratio, it offers a slightly better freeze point and heat-transfer ability. Plus, it’s less expensive.

Propylene Glycol is biodegradable and features low toxicity, making it safer for use around children, pets and wildlife. Some racetracks and off-road parks require PG formulations.

Of course, antifreeze/coolant must provide more than just freeze and boil protection. It also must guard against corrosion, cavitation, scaling and additive drop-out, and it’s up to the additives to achieve these tasks. There are basically three categories of additives, and any of them can be blended with the two glycols mentioned above.

Antifreeze/Coolant Additive Types

Inorganic salts, such as nitrites, phosphates and silicates, are used in the “green” conventional coolants traditionally found at most retailers due to their low price. Conventional additives work by forming a protective layer on metal cooling-system components, helping prevent corrosion. Because these additives are depleted by forming a protective layer, conventional green coolants require regular changes, typically every two years. They are on the environmental watch list (just like nitrates) and, once depleted, are the source of common cooling-system problems, like scale deposits. They can also be incompatible with each other, sometimes leading to drop-out in the form of an abrasive or slime. For these reasons, most vehicle manufacturers have moved away from inorganic salts for newer vehicles.

Organic acids, often referred to as OATs (organic-acid technology) or POATs (poly-organic-acid technology), are much more robust and longer-lasting. Unlike organic acids that coat metal surfaces, organic acids provide corrosion protection by chemically interacting at the metallic corrosion sites. They’re only used when needed, meaning they last much longer. They virtually eliminate drop-out, scaling and compatibility issues inherent to inorganic salts. This type of coolant can be used in a wide variety of applications, even mixing with other coolants as a top-off.

Hybrid-organic-acid technology, often called HOATs, is a combination of inorganic salts and organic acids. They work in tandem to minimize some of the issues with inorganic salts while relying on the organic acids to boost performance.

 

Incompatibility of Inorganic Salts Causes Problems

As mentioned, mixing coolant types that contain inorganic salts can alter the formulation enough to reduce protection. This can reduce the service life of both the coolant and the cooling-system components, leading to the following maintenance issues:

Corrosion of metals in the cooling system, which can lead to failure of the water pump, heater core, radiator and other components.

Scale deposits can form on metal parts, which reduces heat-transfer ability and contributes to overheating.

Additive drop-out, which can occur when incompatible inorganic salts are mixed. An abrasive or slime forms and is deposited throughout the cooling system, leading to poor performance and eventual failure.

Cavitation, or the erosion/corrosion of the cylinder liner, can occur if the coolant provides insufficient protection. Cavitation often results in internal coolant leaks, which can lead to engine failure.

Many of the issues outlined here can be resisted or prevented completely by using antifreeze/coolants with organic-acid technology. While all coolants that pass relevant industry-standard testing provide a minimum level of protection, a properly formulated coolant using organic-acid technology provides the longest-lasting and best protection without the incompatibility issues that come with the inorganic salts found in “green” and hybrid coolants.

Water Quality Critical to Performance

Low-quality or hard water is a leading cause of cooling-system problems. Minerals found in hard water, including magnesium and calcium, react with inorganic salts, like phosphates, found in conventional and hybrid coolants. The byproducts form scale deposits on engine surfaces, reducing heat-transfer ability and contributing to damaging corrosion. For best performance, use only high-quality distilled water when mixing coolant. For maximum convenience, use a coolant pre-mixed with high-purity water.

AMSOIL Antifreeze/Coolants

AMSOIL offers three coolants, all of which offer a unique blend of organic acids. AMSOIL uses di-acid technology, which means both ends of the organic acid are active. This makes them work faster and form stronger bonds for enhanced protection.

AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is formulated for all passenger cars and light trucks. It is premixed 50/50 with high-quality water and EG.

AMSOIL Heavy-Duty Antifreeze & Coolant is dialed in for the unique needs of on- and off-road heavy-duty applications. It is also premixed 50/50 with high-quality water and EG.

AMSOIL Low Toxicity Antifreeze and Engine Coolant is a 100-percent concentrate PG formulation for situations that call for a low-toxicity solution.

AMSOIL Products Help LandCare Innovations Minimize Expenses

AMSOIL Products Help LandCare Innovations Minimize Expenses

LandCare Innovations of Charlotte, N.C. prides itself on providing quality work at a reasonable price, offering its residential and commercial customers a full range of landscaping services that includes lawn care, irrigation systems, outdoor living areas, pools and ponds. Maintenance Manager Tim Wilson relies on AMSOIL products to minimize vehicle and equipment repairs and operating expenses.

Prior to joining the LandCare Innovations team, Wilson worked for an auto dealership, where he acquired a strong background in truck and equipment maintenance. He saw firsthand the value of using AMSOIL products, and it’s something he carried forward to his position in the landscape business.

“One of the major challenges in the landscape profession is keeping the equipment running,” said Wilson. “If there’s a failure, the job doesn’t get done. Then we have to rent equipment, which comes out of our profits. We have 90 employees using the machines and equipment, which includes everything from trimmers to dump trucks, and it’s essential to keep everything running.”

Zero-Turn Mowers

“Our zero-turn mowers are running day in and day out,” said Wilson. “They’re faced with severe-duty service five to six days a week for seven to eight hours nonstop. The premium lubrication qualities provided by AMSOIL products are essential, and we perform oil changes and grease points every 200 to 250 hours.”

Backpack Blowers

Wilson uses AMSOIL SABER® Professional and P.i.® in the company’s BR 600 Stihl* backpack blowers. “The blowers must run constantly at full power to maximize job efficiency,” said Wilson. “I’ve heard other landscape professionals complain about the operation of their two-stroke equipment. We use SABER Professional at 80:1, and our equipment runs clean, with no carbon and no problems.”

Truck Fleet

As for the company’s fleet of gasoline- and diesel-powered trucks, Wilson uses AMSOIL Premium Synthetic Diesel Oil, Signature Series Synthetic Automatic Transmission Fluid (ATF) and Ea® Oil Filters. “We put these trucks through severe-duty service; they’re idling, they’re towing and hauling our equipment in dusty, dirty, hot conditions,” said Wilson. “Although we keep track of mileage, we always end up going past the service interval, and we have no mechanical problems. Extending the oil drain intervals to 10,000 miles, and beyond, saves valuable time. With conventional intervals, I’d be servicing trucks every day, and I don’t have time for that. We know AMSOIL Premium Synthetic Diesel Oil can go past 10,000 miles, and the oil analysis proves it. With AMSOIL products, we just don’t worry about our vehicles and equipment.”

“AMSOIL products have saved our company lots of money. We’ve extended our oil drains from 5,000 to 10,000 miles, the Ea Oil Filters hold up longer and the Signature Series ATF has cleared up our problems with overheating transmissions. Needless to say, our company is sold on AMSOIL products.”

Timberline Landscaping Relies on AMSOIL Products for Reduced Downtime

Timberline Landscaping Relies on AMSOIL Products for Reduced Downtime

Timberline Landscaping Relies on AMSOIL Products for Increased Equipment Life, Reduced Downtime

Timberline Landscaping of Colorado Springs, Colo. has offered residential and commercial customers a full range of landscaping services since 1982, including landscape design, construction and maintenance. As any business owner can attest, reliable equipment is key to success. Timberline owner Tim Emick counts on AMSOIL products to keep his company’s vehicles and equipment in top working order.

Extended Equipment Life

Extending equipment life is essential to any landscaping company’s bottom line. Emick has accomplished this by using a multistage approach that focuses on purchasing high-quality equipment, using premium AMSOIL synthetic lubricants and following sound maintenance practices. The approach has allowed Timberline Landscaping to double the life of its zero-turn mowers, “going from a three- to four-year life span to a six- to seven-year life span,” said Emick. The company has had similar success with its work trucks, “keeping them eight to 13 years” rather than trading them in every four years. With respect to his skid-steers, Emick keeps them “until they reach the 5,000-hour mark, and due to our good maintenance practices and use of AMSOIL products, they’re in such good condition that we’re able to sell them for 2/3 of the original purchase price.”

Increased Reliability and Performance

“We don’t tolerate poor-performing equipment in this business,” said Emick. “It eats into our money-making ability and impacts the crew both physically and mentally. Downtime is not tolerated. If you’re not being productive, you’re not making money. If equipment doesn’t perform well, we simply boot it from the inventory. AMSOIL products have made a noticeable difference to the reliability and performance of our equipment.”

Severe-Service Protection

Among the many jobs Timberline performs for its customers is snow removal, often a daunting task following a heavy Colorado snowfall. In these instances, Emick and his employees push their equipment to the limit.

“The wet, heavy snow overloads the equipment and the equipment is used 24/7 until the snow is cleared,” said Emick. “AMSOIL products provide that extra peace of mind when we’re pushing our equipment to the edge. We’ve never had an engine fail in these instances.”

Reduced Maintenance and Repairs

“I was tired of crawling under trucks late at night to work on or replace an engine or tranny after everyone else went home,” said Emick. “AMSOIL synthetics helped me stop doing that.”
