Synthetic Chaincase Oil

Long-Lasting Performance for ATVs and Snowmobiles – A major seller in Sioux Falls because it matches a hard to find combination product which has properties beyond standard gear oils. 

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.

Other brands sell an 8 ounce version for twice the price! That equates to 4X the price of our bottle! And you don’t get any rust and corrosion protection.

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.

Snowmobile Chaincase
By  DALE,  a  Verified Buyer  from  Picton, Ontario, Canada   on  June 28, 2021

I have used amsoil chaincase oil in the last 5 snowmobiles that I have owned! Never had an issue with the chain or sprockets with 10,000 to over 26,000 km put on my sleds!

Noticeable change
By  CHRIS,  a  Verified Buyer  on  February 10, 2021

Put into my 07 arctic cat F1000. I always used the cat oil and would constantly grind when is shifted in reverse because gears would not engage. And I would never believe a oil would make a difference but now with amsoil it no longer grinds at all. Approximately 400 miles so far no grind at all. I am switching to amsoil for all my machines

This chaincase/ gear oil is 2nd to none. Has a good cling performance and remains where it belongs…on the gears and chain

I’ve use Amsoil chain case lube for years and never had a chain break or gears fail. Excellent product!



Recommended for the drain intervals established by the OEM.


AMSOIL Synthetic Chaincase & Gear Oil is compatible with conventional and synthetic chaincase oils. Mixing AMSOIL Synthetic Chaincase & Gear Oil with other oils, however, will reduce its performance benefits.
