Re: Has Mobil 1 changed???

Ok this is what I have found out so far

The new M1 EP 5W-30 SM dated Oct 2006 just came out of the G.C. and it is MOSTLY mineral oil, presumably Group III. It also contains a good slug of AN and some PAO, but little or no ester

I have the Valvoline in my wifes Jeep
I am also going to try Royal purple in mine and see what does better Also looking to use a Wix oil filter
