AMSOIL Dominator Synthetic 2 Cycle Racing Oil

Better Lubricity Means More Horsepower and Less Piston Scuffing

AMSOIL Dominator Synthetic 2 Cycle Racing Oil contains heavier synthetic base oils that provide greater lubricity (or slipperiness). The function of lubricity is to reduce friction, increase horsepower and prevent piston scuffing. Tightening within the cylinder, caused by high temperatures, increases friction and wear, robbing valuable power from the engine. AMSOIL Dominator's high lubricity increases horsepower and torque by reducing friction and provides maximum protection against piston scuffing, resulting in better throttle response and overall two stroke performance.

Cleaner 2 Stroke Engines

Because 2 stroke engines burn oil, it is important for the oil to burn clean to prevent carbon build up. The three primary advantages of using clean-burning 2 cycle oils are:

• reduced spark plug fouling (spark plug fouling causes backfires and prevents the motor from running smoothly)
• no ring sticking (ring sticking decreases performance and can lead to motor seizure)
• reduced deposit formation (deposits can cause pre detonation, burn holes in the piston and clog the exhaust port)

AMSOIL Dominator Synthetic 2 Cycle Racing Oil is specially formulated to burn clean, ensuring optimal engine performance. It contains highly pure AMSOIL synthetic oil and strong, high-temperature detergent additives to prevent spark plug fouling, ring sticking and deposit formation that can clog the exhaust port and limit the action of exhaust power valves found on high-performance 2 stroke engines. AMSOIL Dominator is an optimized product for severe service.

Protects Against Piston Scuffing and Crankshaft Bearing Wear

High performance 2 stroke 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. Increased pressure on crankshaft bearings promotes metal-to-metal contact, wear and pitting.

High heat and pressures require a tough oil. AMSOIL Dominator Synthetic 2 Cycle Racing Oil is formulated to handle high heat better than mineral oils, providing improved film strength and more lubricity for an extra measure of protection against piston scuffing and crankshaft bearing wear.

Applications — Injector Oil or Premix

AMSOIL Dominator Synthetic 2 Cycle Racing Oil is recommended for use in high performance stock or modified 2 stroke motors, including air- or liquid-cooled snowmobiles, PWC (personal watercraft), motorcycles (Moto X), ATVs, go karts and outboard motors*. AMSOIL Dominator is good for use with exhaust power valves, coated or non-coated racing pistons and high octane race fuels.

AMSOIL Dominator 2 Cycle Racing Oil may be used as an injector oil or as a premix at a mix ratio of 50:1 (2.6 ounces per U.S. gallon of gas) where API TC or JASO FC oils are specified. AMSOIL Dominator is 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.
