Race-Proven 2-Stroke Protection
Racers can't win what they don't finish. That's why AMSOIL formulators built DOMINATOR 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.

Excellent Film Strength and Clean Burning
DOMINATOR is purpose-built for outstanding film strength and lubricity. It is engineered with carefully selected higher-viscosity synthetic base oils to withstand the high heat and pressure common to high-performance and racing applications. Its anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
Formulated with clean-burning synthetic base oils and powerful high-temperature detergent additives for exceptional deposit control. It helps prevent the power-robbing carbon deposits that cause ring sticking, exhaust port blocking and pre-ignition.
