Hi guys, I just bought my first BMW...Anyway I bought it from this 70 year old woman. The car is mint like an old grandma just drove it off the lot. So anyway I go to change the oil and I have never seen oil so thick before! On the odometer it says oil change -3100??? Does that mean she went 18k miles with no oil change? The car only has 55k miles. Should I be nervous or do you think things will be ok?
