Application Chart DOMINATOR Synthetic 2-Cycle Racing Oil

New AMSOIL DOMINATOR Synthetic 2-Cycle Racing Oil is a robust formulation specially engineered for unsurpassed protection in high performance two-cycle motors, both on and off the track. It contains heavier synthetic base oils that provide more lubricity for "on the edge" operation. DOMINATOR reduces friction and protects pistons and bearings subjected to the rigors of racing. DOMINATOR contains the right additives for clean motor operation.

Provides excellent film strength for high heat, high RPM motors

Reduces friction for maximum power
Recommended for use with coated or non-coated racing pistons Recommended for use with exhaust power valves
Recommended for use with high octane racing gas Burns clean; Prevents ring sticking and plug fouling
Provides excellent protection at 50:1 pre-mix or in injection system

Product Code: TDR

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.

Clean Burning

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 severe service.

Applications

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 be minimized.

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 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.

Even though AMSOIL 2-Cycle Oils have been optimized for speci.c applications, they are multi-functional and recommended for use in many areas. The chart rates each oil’s performance abilities per application as follows:

Excellent: "The" primary recommendation for the oil. This is the best possible choice for the application. The oil is speci.cally designed for the operating conditions of the motors in these markets. There is only one "Excellent" recommendation per category.

Very Good: A main recommendation for the oil. Identi.es an oil that is very good for the operating conditions of these motors.

Good: A secondary recommendation for an oil. The oil was not speci.cally designed for these applications, however, the chemistry in the oil is suited to the operating conditions of these motors.

Not Recommended: Identifies applications where the product was not intended for use. "Excellent" rated products offer superior performance.

Racing: (1) Not recommended 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.

(2) Excellent for racing or modified motors. Very good for recreational use.

*Recommended for all (DFI) direct fuel injected, (EFI) electronic fuel injected, and carbureted motors. Outboard motors include Mercury® Optimax,® Johnson® & Evinrude® FICHT® & E-TEC,™ Yamaha® HPDI, Nissan® & Tohatsu® TLDI®
