Many of us tried Mobile 1 5W20 and loved it. I put it in my last car and drove it from 60-some thousand miles to 116,000 on 5W20.

John (BoilerupXfire) is the one who suggested it to me. My car shifted better after putting it in - of course, by the time it had 100,000 miles on it, it shifted way better - what these cars' transmissions need is MILES!!!

Change your differential fluid while you are at it - I would need to go look, but I think it was 75W80 we used - Mobile 1, of course.
