Re: Has Mobil 1 changed???
Hi Norm:
Funny you bring this up.Like Chris I have run mobil 1 in everything since the early 80's even the snow blower and mower.I used the miles as a guide for changing 5000 max but more the color on the dip stick.It would always be so clear in the car and truck I could not see it on the stick. In the last year I have changed the oil in both vehicles probally three times more than usual for being dark but blamed it on the fact we did a intake gasket on the car and the truck being a 89 just picked up some gunk.The last change I also put valvoline in the car and the same day Mobil one in the truck. The car I just checked is clear on the stick and the truck after 800 miles is dark brown which is not normal.
It has always been a probuct I stood by but I think you are on to something.I am going to take it out of the truck to see what happens.
My last dodge ram went over 450,000 miles with it never apart and is still running.
