2002 Magnum 325 4X4
What kind of oil is supposed to go into the rear differential of this machine? The manual says 80-90w GL-5 and the dealer says to run Polaris AGL which I have a gallon of but it seems to me to be pretty thin to be using in the rear gear housing. Come to think about it all of the Polaris oils seem pretty thin for their intented use. Any help would be greatly appreciated.
