Like I said the BMW oil is a higher quality. Rated in there cars for 1year 15k mile oil changes. It's around $7 a qt here. Compared to the Mobil 1 at 9.84 a qt. did you pay the difference on the oil changes or were they free? - Never mind I reread your original post and see I misunderstood what you said, you have had 7-10 oil changes performed at the dealer, I thought they were complimentary. Anyway, there is a TSB for oil consumption on early Z's. Send me your VIN and I will check it Monday.
