Mobil 1 LS 75W140 with friction modifier
Tried a search and no luck. Just bought a 2006 F-150 4X4 with 98K. Going to have both diffs serviced. I already ordered Mobil 1 LS 75W140 for the fills. What kind of luck have y'awl had with running this gear oil in a limited slip rear without having to add more friction modifier?
