I have searched, but could not find much info on it? I know about the lawsuit a while back. How is it now? I won't be changing it again for 4 years/25K miles (yes your read that right). Last differential service was 4 years ago and I put only 25K miles on that oil. It was done by Isuzu dealer, so I am sure they used Castrol something.
Oil will go into Rear LSD (with a tube of LSD Additive), front and shift-on-the fly. Transfer case is getting M1 Mercon V/Dex 3--already had it on hand.
