AMSOIL for Racing


Professional racers across North America recognize AMSOIL products as the best and mosteffective available. The number of championships and checkered flags claimed by AMSOILsponsored racers is testament to the extraordinary performance AMSOIL products provide.

Many other oil companies formulate advancedlubricants available only to the professional racersthey sponsor. By their standards, all AMSOIL formulations are advanced. The same products used by AMSOIL-sponsored professional racers across all disciplines are the same products available to you. 

Here’s what some have to say about AMSOIL synthetic lubricants.“It’s not uncommon for us to see engine temps over300º. There’s no other oil I’d trust on race day.”Scott Douglas11 World Championships 

“We never touch our engines all race weekend.The other guys are swapping engines Saturday night for a new engine for the race on Sunday. We are just running the same stuff, and everybody is really impressed by it.”
- Erik Buell, EBR Racing 

“There’s only one oil I trust to protect my Rotax® engines.”

- Steve Schuering Owner, Scheuring Speed Sports Briggs & Stratton is the world’s largest small-engine manufacturer, and karting is the fastest-growing motorsport in the U.S. Tens of thousands of racers rely on Briggs & Stratton engines at the track every weekend. While using competing oils in the extreme operating conditions of its racing motors, Briggs & Stratton experienced myriad failures and issues, including accelerated wear, foul odor, oil vaporization and very short change intervals. Looking to resolve the problems, Briggs & Stratton chose AMSOIL to formulate Synthetic 4T Racing Oil. AMSOIL entered the partnership enthusiastically, formulating an oil that provides outstanding protection and performance in extreme operating conditions. Providing an oil exclusively for Briggs & Stratton’s highest-performing racing engines strengthens the AMSOIL reputation for quality and increases brand recognition.

Premium Oil for Severe Racing ApplicationsSynthetic 4T Racing Oil is formulated specifically to handle the severity of Briggs & Stratton modified competition engines used in kart, junior drag, quarter midget and other racing applications and is recommended for any four-stroke air-cooled competition engine, whether single- or multi-cylinder, splash- or pressure-lubricated.

Combining the protection qualities of a heavy oil with the performance benefits of a light oil, Synthetic 4T Racing Oil helps racers elicit the most horsepower and longest life from their engines. It provides outstanding protection in both stock karts and limited-mod kart applications running over 10,000 rpm, with no sacrifice in horsepower. Racers using competing oils need both a light and a medium oil to achieve a similar combination of protection and horsepower. Synthetic 4T Racing Oil was dyno-tested using the Briggs & Stratton Animal engine, and proven to provide outstanding performance in the most-extreme conditions possible. It effectively resists the elevated heat common to high performance racing engines, and it protects against the formation of corrosion between races and during longer storage periods. 

“We are really excited about this relationship with AMSOIL,” said Director of Briggs & Stratton Racing David Klaus. “After a year in development and our first race season under our belt, racers are seeing the benefits of an oil engineered specifically for the environment in which it operates.”

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.


Help 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. 

Shear Stability

Many gear lubes are formulated with viscosity index (VI) improvers in order to ensure multi-grade viscosity protection in both hot and cold temperatures. VI improver additives keep lubricants from becoming too thick to flow in cold temperatures and too thin to protect in high temperatures. However, shearing forces within equipment can cause these additives to break down and lose viscosity. 

AMSOIL Severe Gear effectively protects against thermal runaway by maintaining its protection qualities, even in severe, high-shear operating conditions.

The superior viscosity protection, viscosity index and shear-stability properties of AMSOIL Severe Gear Synthetic Gear Lube effectively protect equipment from the devastating effects of thermal runaway. Severe Gear Synthetic Gear Lube is ideal for severe-duty applications, including towing, hauling, steep hill driving, commercial use, plowing, racing, off-road use, rapid acceleration, frequent stop-and-go operation and high ambient temperatures.
