Just finished putting together a chrysler 8 3/4 rear axle to put in my 91 half ton short bed four wheel drive truck, I live in idaho where winter is brutal and summers get hot. In the past I have always ran valvolone synpower 75w-90 and in fact I have synpower 75w-90 in the front axle on my truck which is a dana 44.
I was considering running amsoil severe gear in this 8 3/4 and the reason why is because it's a chore to completely drain the oil from this axle, you have to pull the axle shafts out and drop the third member to completely drain it.
I could use a suction method but it wouldn't get all of it out. Anyways I want to run a good synthetic oil in this axle.
Right now my local Napa auto parts has valvoline 75w-90 gear oil on sale for 9.99 a quart. They also sell amsoil severe gear 75w-90 at 15.99 a quart. This axle takes just shy of 3 quarts to fill, so I'll be buying 3 quarts. The amsoil would cost me 48 dollars and the valvoline would cost me 30. Is the amsoil worth the extra 18 dollars? Or would the synpower work just fine. What oil would you reccomend? Chrysler reccomends an 80 to 90 wieg oil for the 8 3/4.
I'm willing to buy the amsoil, but if the valvoline will do just as good then I don't mind saving 20 bucks.
