What gear oil?

meknized · 08-10-2007, 04:53 PM

It's time for me to change my rearend oil and am wanting to know what gear oil all of you use and recommend. The car is street/strip and has the Auburn pro diff. Is any friction modifier recommended? I haven't changed the lube in about 6 yrs and have forgotten what was even in there?

If you get some 90 weight Royal purple, it comes with a limited slip additive already so no need for friction modifier...

Ok, I have the Royal Purple in the engine and tranny. How many quarts for the rearend?

I think it's two, maybe little more or little less, just fill until the fluid spits back at ya!
