Sub-Zero Synthetic 2 stroke snowmobile oil is formulated with select synthetic base oils and advanced additive technology. We design it specifically for the demands of snowmobile engines. As a result, our premium, smokeless, low-odor, 2T snowmobile oil delivers optimum engine performance and maximum sled protection. Furthermore, its special low-ash additive system minimizes harmful carbon deposits and spark plug fouling. Finally, it prevents both piston ring and exhaust power valve sticking and provides ultimate high-temperature protection to air-cooled 2-stroke engines. We recommend our snowmobile oil for recreational and racing applications, including Arctic Cat, Polaris, Ski-Doo & Yamaha Snow Machines.
