What is the advantage of using an expensive synthetic rear end lubricant over standard petroleum based gear oil + posi additive as Corvettes came from the factory with?
I'm doing some service work on mine and drained out all the old stuff the previous owner put in (Red Line, heavywieght! stuff is "blue" colored) and was considering just going back to G.M. stuff the factory put in the first place!
I just don't buy into all the advertising hype!
Looking for opinions on synthetic vs. petroleum based for the rear diff.
