Just did the Weir Performance Max Grip plates in the rear diff of my 8 and was wondering what oil you guys are using. I had Redline heavy duty shockproof in mine before.

They recommend petroleum based gear oil.

I'm not sure how different your diff is but TRE recommends Redline 80w140 or 75w140NS(if you want to really increase the lock up)
