Can somebody give me advice on which oil to use in the diff of my 94 Z28?
many thanks

i've used the redline diff oil. the same weight as the hand book states (think its 75w-90) off top of my head. But get one that has additive added already and one that doesn't. The diff should take both so its still got additive in overall. Assuming you have clutch type posi rear if it chatters too much or locks out not to your aste you can put more additive in to make it 'slip' a little more.
