Synthetic Chaincase & Gear Oil

Long-Lasting Performance for ATVs and Snowmobiles

Synthetic Chaincase & Gear OilDesigned Specifically for Chaincases & Gearcases

To reduce initial costs, some enthusiasts use automatic transmission fluid or gear lube in their snowmobile and ATV chaincases and gearcases. Neither fluid, however, is engineered for these applications. Automatic transmission fluid is a hydraulic fluid formulated without the extreme-pressure additives needed to provide enhanced wear protection, leaving gears and chains vulnerable to premature failure. Automotive gear lube is designed to lubricate hypoid gears and is too thick for proper chain and gear lubrication in powersports applications, impairing circulation and leading to wear and decreased energy efficiency.

AMSOIL Synthetic Chaincase & Gear Oil is specifically engineered to meet the demands of enclosed chaincases and gearcases, providing extreme-pressure protection and low-temperature fluidity for superior performance and protection.

I’ve been using this gear oil in my snowmobiles for the last 10 years with never a failure and little to no wear very little to no metal on the magnet when I change the oil on regular intervals. Cost less than Arctic Cat stuff
