i have looked into it before. i was warded off using lucas, and told that delo is the best. it must not have limited slip additive in it.
the application is a 500hp(450 at the wheels) 2001 mustang bullitt 8.8 rear end with an auburn pro differential. its daily driven during warm months in se michigan, it is beat on and occasionlly goes to the strip.
auburn recommends a non snthetic 80-90 with gm or for ls additive or their proprietary additive. i just add enough of the auburn additive to stop it from chattering which it doesn't take much(1-2 ounces for 2 3/4qts)
