DOMINATOR, an AMSOIL exclusive formulation, lubricates
and protects high performance two-cycle motors, both on and off
the track. High performance motors, particularly those that are
modified, operate hotter and at higher RPMs than recreational
motors, and they need good oil for peak performance. DOMINATOR
is engineered for racing. It has the right film strength and clean
burning properties for "on the edge" operation.
Super Film Strength
High performance two-cycle motors have high compression ratios,
which significantly increase combustion chamber heat and crankshaft
bearing pressures. Hot combustion processes quickly burn off
and evaporate light oils and cause rapid piston expansion, decreasing
piston-to-cylinder wall clearances. This promotes piston scuffing
and possible seizure. And increased pressure on crankshaft bearings
promotes metal-to-metal contact, wear and pitting.
High heat and pressures require tough oil with
better film strength and more lubricity. DOMINATOR, constructed
with AMSOIL heavy synthetic oil, handles high heat better than
mineral oils and provides improved film strength and lubricity.
DOMINATOR reduces friction and provides an extra measure of
protection against piston scuffing and crankshaft bearing wear.
High combustion processes require the proper additives and oils
to control deposits. DOMINATOR contains strong, high temperature
detergent additives and highly pure AMSOIL synthetic oil. It
prevents deposits that cause ring sticking, plug fouling and
exhaust port blocking. DOMINATOR is an optimized product for
DOMINATOR is recommended for use in high performance stock or
modified two-cycle motors, 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-cycle oils, however, mixing oils should
Use at 50:1 pre-mix ratios (2.6 oz. oil per
U.S. gallon of gas) or as injection oil where JASO FC or API
TC oils are specified. 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 periodically inspected.
