'71 Barracuda Rear End
« on: August 26, 2015 - 04:44:33 PM »
Looking for some advice: I currently have an 8 3/4 rear end that I just put in a new 3.23 posi center section gear set-up.  What is the best gear oil to put in it?  I have heard to not use synthetic, to only use synthetic, to use any cheap gear oil with a separate additive . . . just trying to get some opinions!

When i put in my Dana I asked Dr Diff this same question, he told me to use the standard gear oil (Walmart) and add GM or Ford additive.

Non synthetic with additive for sure grip , 80-90 is fine
