Cold Flow

Two- and four-stroke snowmobiles use different oiling systems, but both require oils with excellent cold-flow properties for maximum protection. Today’s two-stroke snowmobiles direct less oil to critical components, through narrower passages, for longer distances. Oils that thicken at cold temperatures are difficult to pump and can fail to reach components at startup. Four-stroke engines, meanwhile, are splash lubricated. Thick oil can cause difficult starts while failing to properly lubricate at startup, increasing engine wear. AMSOIL synthetic two- and four-stroke snowmobile oils feature outstanding cold-flow properties for maximum engine protection in the coldest weather.

Warranty Secure™

Original equipment manufacturers (OEMs) want you to think you have to use the OEM-branded oil – which is typically more expensive – to provide your sled adequate protection. They also want you to think that you have to use the OEM oil to comply with new-equipment warranty requirements. It is illegal for a vehicle manufacturer to tie the warranty of its product to the use of the manufacturer’s own lubricant. In short, you have the freedom to choose whichever oil you think is best for your sled. While snowmobile manufacturers may be experts at building sleds, none of them can match AMSOIL expertise when it comes to formulating synthetic two-stroke oils. AMSOIL synthetic snowmobile oils are Warranty Secure™, keeping your factory warranty intact. They’re outstanding choices for Polaris®, Ski-Doo®, Arctic Cat®, Yamaha® or other brands of sleds.

Exhaust Power Valve Cleanliness

Today’s two-stroke snowmobiles produce more power and run hotter than previous models. This can cause exhaust power valve deposits to form, which can cause sticking and reduced performance. AMSOIL synthetic two-stroke snowmobile oils are formulated with added detergency to keep power valves clean and moving freely for maximum performance.

Piston Protection

Snowmobile engines are more advanced than ever. They deliver increased power than their predecessors while producing fewer emissions and, in the case of two-strokes, using less oil. To guard against piston scuffing and wear, today’s powerful sleds require robust oils capable of withstanding increased heat and friction. AMSOIL synthetic snowmobile oils feature naturally tough film strength for outstanding piston protection.
