This question came up on a Silverado FB group I follow.
There are clutches in the G80 that are used for the lockup. My question is, do they need a LS additive? Obviously it won't hurt. The guy wants to know if he can run Delvac 1 75w90 in the front and the rear diffs. Front's a no brainer, but the clutches in the rear have me wondering.
