Going to change gear lube in chaincase and tighten chain and wondering what weight oil I can use? Looked in the manual and race handbook and all they say is to use Ski-doo chaincase oil, which is fine, but I have some Amsoil 75W-90 left from previous sled and would like to use it up since they recommend to change/tighten after each first few rides. And lets be honest Ski-doo oil isn't cheap, so want to use up what I have before buying Ski-doo. Any info appreciated..
