Schmism were you suprised when you found out that it took 8 quarts of oil to fill you BMW. I bought a porsche boxster last year and the first time I took it to get its oil changed they handed me a bill for $115.00 I kind of gulped and said oh well you buy this kind of car you pay for the servicing. When I looked at the bill it showed they had put 10 quarts of oil in it. I complained to the person that I had paid and had them call the service manager out. The service manager listened to me complain that they had made a mistake and there was no way my car could have held 10 quarts of oil. He was very nice and asked me if that was my first Porsche I said yes and he took me into his office and showed me the service manual, it actually takes 10 quarts. When I apologized he said he gets to have this talk with almost every new owner. It is amazing that they use way more oil than my duramax diesel does
