    DIFF oil

    SO there is a thread on motor oil but not diff oil. Lets see what you guys are using. And also what brand. Let us know if you are using additive or not.

    I'm using Red Line with the slip additive. I think I'm going to run Mobil 1 75W-140 with limited slip lube next change.

            What are your plans for your car? Redline is in all my cars. I mix half non slip and half limited slip to try and get a little more lockup. But i only recommend this on new clutches in the LSD. Check out http://www.factory3performance.com/s...exd.asp?id=309

                  75w-140 GL-5 Valvoline with friction modifier its more of a 60/40 mix to give a lil more lock up
