Description
On the track, you can’t win if you don’t finish. That’s why AMSOIL formulators created DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of engines designed for racing. These engines run flat out, yet engine reliability is critical. DOMINATOR does an exceptional job of protecting high-performance engines. It offers the durability professional racing teams depend on and the confidence to push engines to the limit.
Race-proven benefits
Excellent film strength for high-temperature, high-speed/high-rpm engines
Anti-friction formula for maximum power
Burns cleanly. Helps prevent ring sticking
Protects coated and uncoated pistons

Racing Testimonial: AMSOIL Snow Oil Saves Engine
During the Pro Open final at the opening rounds of the AMSOIL Championship Snowcross, Ski-Doo professional rider Lincoln Lemieux lost all his engine coolant after a clamp broke. Despite the intense heat that destroyed the exhaust valve seals, O-rings and head gaskets, AMSOIL DOMINATOR Synthetic 2-Stroke Racing Oil protected Lemieux’s engine so well that the team could reuse the engine after replacing the melted components.
Excellent lubricity and film strength
State-of-the-art two-stroke engines operating in racing conditions run under severe conditions. They are modified for higher compression ratios, higher rpm and easier combustion, all of which increase heat and pressure. High heat can quickly burn off thin lubricants and cause rapid piston expansion, reducing piston-to-cylinder wall clearances and increasing the likelihood of scuffing and piston failure. High pressure can exceed the film strength of low-viscosity lubricants, promoting crankshaft bearing wear.
DOMINATOR is formulated for excellent film strength and lubricity. It is made with carefully selected higher-viscosity synthetic base oils to withstand the high heat and pressure common in high-performance and racing applications. DOMINATOR’s anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
Excellent cleanliness
Oil and fuel burned in the combustion process leave destructive deposits on pistons, rings and in the combustion chamber. Excessive deposits can lead to catastrophic engine problems, including ring sticking, exhaust port blocking and pre-ignition. AMSOIL DOMINATOR is formulated with clean-burning synthetic base oils and powerful high-temperature detergent additives for excellent deposit control. It helps prevent power-robbing carbon deposits that cause ring sticking, exhaust port blocking and pre-ignition. AMSOIL DOMINATOR is built for hard use.
RACING IS RESEARCH ™
During the opening weekend of the 2015/16 AMSOIL Championship Snowcross, Ski-Doo* RS600 professional rider Lincoln Lemieux suffered a broken hose clamp, losing all coolant from the system. The resulting intense heat melted the exhaust valve seals, O-rings and engine gaskets.
DOMINATOR Synthetic 2-Stroke Racing Oil, however, delivered outstanding protection despite the intense conditions. The rings and pistons were still free and the crankshaft rotated freely. Scheuring Speed Sports could reuse the engine after repairing the melted components, providing concrete testimony to DOMINATOR’s superior performance.
Applications
Used in high-performance machines or modified two-stroke engines, including air-cooled or liquid-cooled snowmobiles, personal watercraft, motorcycles (moto X), ATVs, go-karts and outboard motors **. Suitable for use with coated or uncoated pistons, racing fuels and power valves. Compatible with most other two-stroke oils. However, mixing oils should be minimised.
Used in oil-injection and premix applications requiring API TC lubricants. In premix applications, DOMINATOR offers excellent protection at 50:1 (2.6 oz of oil per gallon of fuel), although many racers adjust the mixing ratio according to their setup. Not suitable for use with alcohol or nitromethane fuels.
** Not suitable for long-term use in outboard motors as a TC-W3 type oil, although excellent as a racing oil for short-term use where engines are inspected periodically.
