AMSOIL DOMINATOR® 100% Synthetic 2-Stroke Racing Oil
AMSOIL DOMINATOR® 100% Synthetic 2-Stroke Racing Oil is engineered for competitive and high-performance two-stroke engines. It’s designed to provide exceptional film strength, even under the high temperatures and pressures common in racing scenarios. This oil helps reduce friction for maximum power output and protects against wear, ensuring that critical engine components like pistons and bearings remain in peak condition. It also burns cleanly, reducing the risk of spark plug fouling and exhaust port blocking. Its anti-friction formulation makes it ideal for racing applications where optimal engine performance and reliability are crucial.

DOMINATOR® Synthetic 2-Stroke Racing Oil
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. These engines operate on the edge, yet reliability is critical. 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.
AMSOIL DOMINATOR®️ 100% Synthetic 2-Stroke Racing Oil
Excellent Lubricity and Film Strength
Excellent film strength for high-heat, high-rpm motors Anti-friction formula for maximum power
Burns clean; helps prevent ring sticking and plug fouling Protects coated and noncoated racing pistons
Excellent Lubricity and Film Strength
High-performance and race-designed two-stroke engines operate under severe conditions. They are modified for higher compression ratios, higher rpm and leaner combustion, all of which increase heat and pressure. High heat can quickly burn off light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances and increasing the likelihood of piston scuffing and seizure. High pressure can exceed the film strength of low-viscosity oils, which promotes crankshaft bearing wear and pitting.
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. DOMINATOR’s anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
Outstanding Cleanliness
The oil and fuel burned in the two-stroke combustion process leave destructive deposits on the 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 exceptional deposit control. It helps prevent the power-robbing carbon deposits that cause ring sticking, exhaust port blocking and pre-ignition. AMSOIL DOMINATOR is optimized for severe service.

APPLICATIONS
Use in high-performance stock or modified two-stroke engines, including air- or liquid-cooled snowmobiles, personal watercraft, motorstrokes (moto X), ATVs, go-carts and outboard motors. Good for use with coated or non-coated pistons, high-octane racing fuels and exhaust power valves. Compatible with most other two-stroke oils; however, mixing oils should be minimized.
Use in oil-injected and pre-mix applications that require API TC oils. In pre-mix applications, DOMINATOR delivers outstanding protection at 50:1 (2.6 oz. oil per U.S. gallon of gas), although many racers modify the mix ratio to suit their setup. Not suitable for use with alcohol or nitro-methane fuels.
Not suitable for long-term use in outboard motors as a TC-W3-type oil, although excellent as a race oil for short-term use where motors are periodically inspected.
