what is the best oil for chaincases??

I was using Amsoil in my Arctic Cats but found it made them far more prone to leaking, I've since switched over the Amsoil synthetic 75wt gear oil which is working great and cuts down on the leaks. Also very cheap to use.

I use polaris synthetic in both sleds and it works very,verywell.

I use fully synthetic chain case oil.Dont think the brand is of so much an

importance,the quality is much more important.

Klotz. It's got graphite impregnated into it. Very sticky. Doesn't leak like standard cat oil. Good stuff.
