Sub-Zero Synthetic 2T is a 2-stroke snowmobile oil that we formulate with select synthetic base oils and advanced additive technology. We recommend it as an Arctic Cat, Ski-Doo, Polaris and Yamaha snowmobile oil. Sub-Zero is specifically designed for the demands of hard-running 2-cycle snowmobile engines. As a result, our premium, smokeless, low-odor, oil delivers optimum engine performance and maximum protection. Furthermore, its unique low-ash additive system minimizes harmful carbon deposits and spark plug fouling. It prevents both piston ring and exhaust power valve sticking while providing ultimate high-temperature protection to air-cooled 2-cycle snowmobile engines.
