AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil INTERCEPTOR offers the proven ability to prevent ring sticking, piston scuffing and exhaust-power-valve sticking in modern, high-performance sleds, helping you get the best performance and most years out of your snowmobile.

For instance, most 4-stroke snowmobiles use OW-40 oils. Meanwhile, some other 4-stroke snowmobile engines benefit from OW-30 or 5W-50 oils. 2-stroke engines, on the other hand, use 2T engine oils in most cases. It's very important to look in your snowmobile's owner manual and use the recommended oil you find there.

Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1. It's built to stand up to the devastating effects of high-horsepower, modern engines and provide maximum protection.

AMSOIL synthetic lubricants deliver wear protection, engine cleanliness and fuel efficiency conventional oils simply can't match.

We think AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil is the best all-around snowmobile oil. We also think it's the best snowmobile oil for power valves.

Feed Your Snowmobile Engine Only The Best! The 2- or 4-stroke engine in your sled works hard to ensure you have an enjoyable outing, so make sure you give it the ultimate protection by running AMSOIL engineered synthetic lubricants.

AMSOIL Synthetic Chaincase and Gear Oil. Designed specifically for chaincases and gearcases, AMSOIL Synthetic Chaincase & Gear Oil provides superior protection and performance for enclosed chains and gears found in snowmobiles, ATVs and general equipment.

Better For Older Engines This being said, however, it is still not recommended to use synthetic oil in engines that have experienced significant actions – specifically, those that have reached around 75,000 miles on the odometer.
