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 engine 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.

Two-Cycle Engine Applications and Lubrication Needs
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. See
teardown photos below.
The oil and fuel burned in the two-cycle 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
RACING IS RESEARCH™
AMSOIL disassembled the Rotax® motor from Scheuring Speed Sports’ Ski-Doo®
race snowmobile ridden by Robbie Malinoski during the 2010/2011 professional
snocross tour. Both pistons revealed minimal wear and were suitable for
continued use. AMSOIL DOMINATOR delivered outstanding protection for
Malinoski’s Ski-Doo in the most severe environment.
DOMINATOR® is recommended for use in high-performance stock or modified
two-cycle engines, including air- or liquid cooled snowmobiles, personal
watercraft, motorcycles (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 where API TC oils are
specified. 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
* 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
