AMSOIL AMSOIL DOMINATOR® 100% Synthetic 2-Stroke Racing Oil Description

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.

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 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.

Kinematic Viscosity @ 100°C, cSt (ASTM D445) 7.0
Kinematic Viscosity @ 40°C, cSt (ASTM D445) 35.2
Viscosity Index (ASTM D2270) 166

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.

Great protection

I use dominator in my ATC 250 R and CR 250 in the sand dunes and have never had an overheating problem or excessive smoke. I have used all the two-stroke oils over the last 40 years and by far dominator is the best.

Great

I did not expect much when I added this to my trimmer that was in storage for about a year but wow fired right up and ran great. I fully expected to have issues starting and keeping it started. Very impressed.
