Just picked up a 2003 Trailblazer 400. I didn't get the owners manual with it and was wondering what transmission oil to use. I'm assuming that it probably takes Polaris AGL, but I thought I'd better check.

 

AGL is the best to use or equivalent oil for chain driven gear cases. OPT

 

Thanks!

 

ive got a 2003 polaris trail blazer 250 also and i was wondering is the polaris AGL plus gear oil the stuff to use or could i use something like lucas synthetic gear oil 75wt/90 stuff ?? im asking because i just bought it and rode it a few times.some one said that 10w30 motor oil will work ? i just dont want to blow it up.thanks for any positive input.

 

If you're not sure then it's best to use what's called for then you won't have to worry. 75/90 is way too thick and wont thin down enough to lube the bearings and chain well enough. Motor oil is better than nothing at all,but if you find any oil approved for chain driven gear cases,then it's probably equivalent to AGL. AGL is pretty thin oil. OPT
