High-quality motor oil is critical for maximum performance in modern two-stroke marine motors. Direct fuel injection (DFI) improves combustion efficiency, delivering the extra power enthusiasts want, while leaner gas-to-oil ratios provide the reduced exhaust emissions the government mandates. The leaner ratio leaves less oil to lubricate and protect these hotter, more powerful motors, which invites deposits and wear that threaten engine performance and life. HP Marine is proven to excel in these harsh conditions. It controls performance-robbing friction, heat and wear, yet produces low smoke and has low aquatic toxicity properties. It's an oil as advanced as the engines it protects.

Anti-Scuff / Anti-Wear
Snowmobile engines have evolved to run on leaner gas-to-oil mixtures, increasing harmful friction and heat. INTERCEPTOR's synthetic formulation incorporates high-molecular-weight components with high flash points that resist burn-off. As a result, a greater amount of oil survives the combustion process to provide lubrication and protection. Its excellent lubricity and film strength inhibit metal-to-metal contact. In extreme dynamometer testing, INTERCEPTOR's anti-scuff/anti-wear formula completely prevented piston skirt scuffing.
Excellent Deposit Control
INTERCEPTOR naturally resists harmful deposits due to its thermally stable synthetic formulation. It is additionally fortified with high-temperature detergency and dispersancy additives that provide excellent engine cleanliness. In extreme dynamometer testing, INTERCEPTOR completely prevented piston ring and exhaust power valve sticking for maximum performance. It also limited piston, combustion chamber and spark plug deposits for reliable operation.

Excellent Lubricity and Film Strength
High-performance and race-designed two-stroke engines operate under severe conditions. They are modified for higher compression ratios, higher rpm and leaner combustion, all of which increase heat and pressure. High heat can quickly burn off light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances and increasing the likelihood of piston scuffing and seizure. High pressure can exceed the film strength of low-viscosity oils, which promotes crankshaft bearing wear and pitting.
DOMINATOR is purpose-built for outstanding film strength and lubricity. It is engineered with carefully selected, higher-viscosity synthetic base oils to withstand the high heat and pressure common to high-performance and racing applications. DOMINATORs anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
Outstanding Cleanliness
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 can lead to catastrophic engine problems, including ring sticking, exhaust port blocking and pre-ignition.
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
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, 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-stroke oils; however, mixing oils should be minimized.

Anyone who’s owned or operated a two-stroke string trimmer, chainsaw, blower or other piece of equipment has been there before. You repeatedly pull the starter cord and adjust the choke, but it’s still hard to start. And, when it finally fires up, it runs rough and threatens to quit. Hard-starting, rough-running equipment is not only frustrating, it lacks the power to work as efficiently as you want.
What causes hard-starting equipment?
Heavy carbon deposits in the exhaust port and on the spark arrestor screen are often to blame. Here’s how it works.
Internal combustion engines require a steady supply of air to run properly and produce maximum power. The engine draws air through the intake and burns it, along with the fuel/oil, in the combustion chamber. The moving piston expels the exhaust gases through the exhaust port and spark arrestor screen on the muffler. In a properly running engine, this happens thousands of times a minute and goes unnoticed by the operator.
Two-stroke oils with poor detergency properties, however, can allow carbon deposits to build-up in the exhaust port and on the spark arrestor screen. Carbon chokes off airflow, which causes the engine to slowly lose power and run poorly. Soon, it becomes hard to start or fails to run altogether unless you clean the exhaust port (which requires removing the muffler) and spark arrestor screen. Most operators don’t want to waste time cleaning deposits, especially busy professional landscapers who need to complete jobs quickly and efficiently.

Two-stroke oils with poor detergency properties, however, can allow carbon deposits to build-up in the exhaust port and on the spark arrestor screen. Carbon chokes off airflow, which causes the engine to slowly lose power and run poorly. Soon, it becomes hard to start or fails to run altogether unless you clean the exhaust port (which requires removing the muffler) and spark arrestor screen. Most operators don’t want to waste time cleaning deposits, especially busy professional landscapers who need to complete jobs quickly and efficiently.
