DOMINATOR Synthetic 2-Cycle Racing Oil

Race-proven, anti-friction chemistry provides an extra measure of protection against piston scuffing and bearing wear. Superior film strength provides protection in engines that can exceed 10,000 rpm. Burns clean; helps prevent ring sticking and plug fouling. Suitable for use with exhaust power valves.

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 RPM 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.

AMSOIL DOMINATOR Synthetic 2-Cycle Racing Oil is a robust formulation specially engineered for on edge performance two-cycle motors, both on and off the track. It contains heavier synthetic base oils for pressure and friction of race-engineered engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed beyond these limits.

• Excellent film strength for high heat, high RPM motors
• Anti-friction formula for maximum power in all temperature extremes.
• Protects coated and non-coated racing pistons
• Reduces friction for maximum power
• Recommended for use with high octane racing gas
• Provides excellent protection at 50:1 pre-mix or in injection system

All major two-cycle racing turns to DOMINATOR, an AMSOIL exclusive formulation.

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.

OUTSTANDING CLEANLINESS

• • Formulated with clean-burning synthetic base oils and powerful high-temperature detergent additives for exceptional deposit control.
  • Helps prevent power-robbing carbon that causes ring sticking, exhaust port blocking and pre-ignition.
  • Optimized for maximum performance despite severe service.

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 are avoided reducing common catastrophic engine problems, including ring sticking, exhaust port blocking and pre-ignition. So many believe these issues are inherent with 2-cycle ownership – no so with Dominator injector oil.

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.

RACING IS RESEARCH™ – Testimonial

During the opening weekend of the 2015/16 AMSOIL Championship Snocross season, professional rider Lincoln Lemieux’s Ski-Doo* RS600 suffered a broken hose clamp, allowing the coolant to pump from the system. The intense heat that resulted melted the exhaust power valve covers, O-rings and engine gaskets. DOMINATOR Synthetic 2-Stroke Racing Oil, however, delivered exceptional protection despite the severe conditions. The rings and pistons were still free and the crankshaft turned freely. Scheuring Speed Sports is able to reuse the engine after repairing the melted parts, providing concrete testimony of DOMINATOR’s superior performance.

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

 

Reviews

Great protection

#1 the Amsoil Quickshot for the fuel – prevents water separation and ethanol problems throughout the entire fuel system – Product of the year a SEMA 2010 by the way!

#2 Amsoil Power Foam for instant clean-up of intake and valve carbon issues as well as an overall degreaser and parts cleaner.
