Synthetic Snowmobile Oil FAQs

Can I register my snowmobile for the AMSOIL Runs on Freedom warranty?

YES. Visit The Runs On Freedom page for limited-warranty terms & conditions and to register your sled.
It covers engine repairs for two years or 5,000 miles (8,000 km), whichever comes first, on current-model year or newer sleds that use AMSOIL INTERCEPTOR Synthetic 2-Stroke Oil exclusively.

Can I use AMSOIL synthetic snowmobile oils without voiding my snowmobile’s warranty?

YES. Using AMSOIL synthetic snowmobile oils has no effect on snowmobile warranties. A federal law called the Magnuson-Moss Act (1975) prevents original equipment manufacturers from putting conditions on warranties attached to any product or service identified by brand, trade or corporate name, unless the manufacturer provides that product or service free of charge. This means consumers have the freedom to use aftermarket products of their choice without fear of losing the original limited or implied warranty. For additional information, visit, or contact the AMSOIL Technical Department at (715) 399-TECH (8324) or

Is it okay to switch to a synthetic oil after using conventional (mineral) oil? How do I make the switch?

YES. Contrary to popular myth, no break-in period is required before making a switch and any engine can safely change at any time. Most performance engines are filled at the factory with the synthetic oil specified by manufacturer engineers. In 4-stroke engines, we recommend using AMSOIL Engine and Transmission Flush if your engine has a questionable history or is known to have deposits. It’s also great insurance if you simply want to give your vehicle a fresh start.

Can AMSOIL Formula 4-Stroke® 0W-40 Power Sports Synthetic Motor Oil be used in new four-stroke snowmobiles?

Yes. AMSOIL Formula 4-Stroke Power Sports Synthetic Motor Oil is specifically formulated for use in small, hard-working four-stroke engines and is ideal for four-stroke snowmobiles and ATVs.

Does AMSOIL have a two-stroke oil recommended for power valves?

Yes. AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil is recommended for power-valve applications. It provides optimal detergency to keep power valves clean in addition to superior anti-wear protection. AMSOIL INTERCEPTOR is suitable for use in sleds with or without power valves.

What grease should I use? How often should I grease the fittings on my powersports vehicle?

Follow the manufacturer’s recommendation. In addition to grease rating, it is important to use the recommended thickener type (Calcium, Lithium, Aluminum, etc.). Grease compounds are not universally compatible with each other. In addition to following your vehicle’s periodic maintenance chart for grease service, it is good practice to refill fittings after using in extreme conditions such as mud and water. AMSOIL Synthetic Water Resistant Grease is recommended for ATVs, UTVs, snowmobiles and boat trailers.

Do I need to clean my EFI system?

Most gasoline sold today includes some mild detergents for cleaning fuel systems. Because powersports vehicles are used in extreme terrain, conditions and weather, it is good practice to use a fuel system cleaner such as Quickshot SE Additive & Stabilizer periodically. In addition to the removal of accumulated deposits, Quickshot SE Additive & Stabilizer will stabilize fuel during storage and combat the corrosive tendencies of today’s ethanol fuels. AMSOIL Quickshot SE Additive & Stabilizer is recommended for small engines and powersports equipment.
