Well, I ran Mobil 1 in my wife's old 86 528e from 40k to 180k. I used 0W30, 5W30 and 10W30. I used more of the 0W30 than anything else. I never did a UOA, but I has no measurable consumption with the 0W30. Many old BMWs report using xW40 and xW50 in order to slow oil consumption. I never had to do that. My gut feel was that the 0W30 was Mobil 1's best xW30. Just one guy's humble (very humble) opinion.quote:
