Thanks Loren. The mechanic at the dealer said any API GL-5 rated hypoid gear oil in 75W-90 weight would be fine in the front differential. I am planning on using Red Line 75W-90 API GL-5 + Hypoid Gear Oil. I'm guessing this is a good gear oil...any comments?
I checked the DIY section but want to make sure about this - The same transmission oil can be used in both the front and main differentials on the 996 Turbo? I'm planning on using Red Line 75W-90 gear oil (GL-5 rated) for both.
