Funny because I have only had one problem with my E 83 x3 with 140,000 miles and that is when the radiator overflow cracked Other than that I have had zero problems and now that I use heavy duty mobile one oil in it it does not burn any oil does not even leak

Also my 2004 has a factory oil change interval of 11000 miles. But I change every 5 or 6 thousand it’s cheap insurance
