I use Royal Purple. It has the friction modifier for the limited slip added to it. I think I used 74/145 but check your manual to see what weight you need. There should be a tag on the rear end cover that tells your gear ratio and weight of oil to use. That's what my 02 GT has on it. Pearl02.

75w90 oil. Valvoline I think... Can't remember now. But use the FORD friction modifier regardless.
