I should be about ready to fill my 9" up with oil here real soon. I have a Ford Motorsports Trac Lock billet posi unit with clutches in it. What oil are you guys running or additives. I have 2 new quarts of Mobil 1 LS 75w90 and was going to get 2 more to fill it up. Wanted to see what everyone else likes.
