AMSOIL now offers three new premium synthetic racing oils specially formulated to withstand the rigors of highperformance and racing applications. AMSOIL Dominator® Synthetic 5W-20, 10W-30 and 15W-50 Racing Oils provide superior performance and maximum protection in extreme environments.
Dominator
Ask any snowmobile or two-stroke motocross racer about AMSOIL and he or she knows the name Dominator. AMSOIL Dominator Synthetic 2-Cycle Racing Oil has earned a reputation for providing
maximum power output while maintaining maximum protection in two-stroke racing and high-performance applications. The name recognition, reputation and superior performance of Dominator Synthetic 2-Cycle Racing Oil is so widespread, AMSOIL has adopted the Dominator name for its new line of racing oils.
Three Viscosities, One Additive Package
Racing and high-performance engines subject motor oil to elevated RPM, high temperatures and shock-loading. AMSOIL Dominator Synthetic Racing Oils were developed to address these extreme conditions and provide high-quality AMSOIL performance and protection for a variety of racing and high-performance applications. All three Dominator Racing Oils feature the same additive package, providing maximum durability in multiple viscosities. Their shear-stable formulation was engineered to provide maximum horsepower without sacrificing engine protection. Dominator Racing Oils provide
straight-grade protection in a multi-grade formulation.
Maximum Durability, Maximum Wear Protection
AMSOIL Dominator Synthetic Racing Oils feature an additive package heavily fortified with zinc and phosphorus for superior long-term wear protection (see Four-Ball wear graphs). Designed for maximum durability, their shear-stable formulation ensures critical engine components are protected from the start of the race to the checkered flag. The superior additive technology of Dominator Synthetic Racing Oils provides unmatched durability in extreme conditions.
Superior Performance
The proprietary friction modifier of Dominator Synthetic Racing Oils provides reduced friction for maximum power and cooler engine temperatures, resulting in improved lap times and longer-lasting equipment.
Protection from Startup to the Checkered Flag
The multi-viscosity designs of Dominator Synthetic Racing Oils deliver maximum protection in temperature extremes. Dominator Racing Oils offer excellent coldstart protection and maintain superior film strength during high-temperature operation on the track.

Superior-Quality Oils, No Discrimination
Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. For instance, several popular oil manufacturers produce racing oils offered only to high profile racers. AMSOIL receives inquiries as to why the company does not offer “special” or higher-quality oils. The answer is all AMSOIL synthetic motor oils are already formulated to a higher level than competitors’
oils, and AMSOIL Dominator Synthetic Racing Oils are no exception. They provide maximum performance and superior protection for all high-performance racing and street applications. The same AMSOIL Dominator Synthetic Racing Oils that are used in the engines of
AMSOIL corporately-sponsored racers, including Scott Douglas and Mike Oberg, are available to everyone.
