AMSOIL Snowmobile Oil is Engineered for Extremes

Snowmobiles are exposed to extremely cold and wet conditions that can quickly destroy both lubricants and the components they protect. AMSOIL snowmobile products are engineered to deliver superior protection and maximum performance that unleashes the full potential of your snowmobile, even in the most extreme winter conditions.

AMSOIL Formula 4-Stroke® Powersports Synthetic Motor Oil

Conventional oils thicken in freezing temperatures, limiting their ability to lubricate and protect until the engine warms up.

Formula 4-Stroke flows smoothly at subzero temperatures to ease cold starts, inhibit engine wear and help extend four-stroke engine life.

• Easy cold-weather starts.

• Fast startup protection.

• Inhibits corrosion and wear.

• Maximizes power and performance.

We pushed the limits of a Yamaha Sidewinder LTX.* Watch the video below to see how AMSOIL Formula 4-Stroke performed.

AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil

Modern two-stroke snowmobiles are designed to burn less oil, which generates extreme heat that conventional oils simply can’t handle. The deposits left by burned oil reduce performance and cause accelerated wear.

INTERCEPTOR burns cleanly, preventing piston-ring sticking, piston scuffing and exhaust-power-valve sticking to maximize the performance and life of your two-stroke snowmobile.

• Prevents fouling and sticking.

• Minimizes smoke and emissions.

• Maximizes power and performance.

• Inhibits wear and corrosion.

AMSOIL DOMINATOR® Synthetic 2-Stroke Racing Oil

Racing sleds generate intense heat and extreme pressure that can exceed the protective ability of standard oils.

DOMINATOR is formulated with heavier base oils to protect boosted race engines facing the extreme demands of podium chasing. The unmatched level of engine protection has been race-proven in championship-level competition.

• Protects pistons and rings.

• Boosts torque and power.

• Extends engine life.

• Podium proven. 

A pro racing sled lost all its engine coolant and melted the exhaust power valve covers, O-rings and gaskets. DOMINATOR protected the engine internals and the team was able to reuse the engine after replacing the melted parts. Watch the video below to see how AMSOIL DOMINATOR performed.
