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.

HP Injector is a precise synthetic formulation that exceeds the lubrication demands of modern two-cycle motors. Today's two-cycle outboard motors operate at higher temperatures and at leaner oil and fuel ratios than older motors. This difficult operating environment requires proper lubrication technology to keep motors running long and strong. HP Injector is a premium lubricant engineered with AMSOIL synthetic base oils and MAXDOSE advanced additives. It contains up to 30 percent more additives than other TC-W3 two-cycle oils for "super clean" operation. And because AMSOIL synthetic oils are more durable, they are perfect for lean mixture operations. In addition, this AMSOIL exclusive product produces low smoke and odor and has low aquatic toxicity properties, making it ideal for boats.

HP Injector improves engine life. It prevents deposits that cause ring sticking and ring jacking (carbon build-up behind the ring, forcing it outward), a phenomenon that occurs in modern DFI outboard motors. HP Injector prevents wear. It has excellent lubricity properties and provides a good lubricating oil film, protecting pistons and bearings. HP Injector prevents rust, an important feature where motors are subjected to water. HP Injector provides superior performance in direct fuel injected (DFI), electronic fuel injected (EFI) and carbureted outboard motors, as well as other recreational equipment.

Applications
HP Injector is recommended for use in all two-cycle outboard motors including, but not limited to, Mercury® EFI & Optimax®, Johnson® and Evinrude® FICHT® and E-TEC™, Yamaha® HPDI, Nissan® and Tohatsu® TLDI®, Suzuki®, Mariner® and Force®. Also recommended for use in all two-cycle personal watercraft and jet boats, as well as snowmobiles, motorcycles and ATVs.

Use as injection oil or as 50:1 pre-mix (2.6 oz. per U.S. gallon of gas) where NMMA TC-W3 or API TC oils are specified. Compatible with mineral and synthetic TC-W3 type two-cycle oils, however, mixing two-cycle oils should be minimized.
