I have 9000 miles on my 2000 540 and have yet to have my first oil change. According to the service light, I am schedule for my first at ~15000. Do you follow the BMW computer recommendation or get it done more frequently -- every 7500 miles? The recent concern about the faulty filters has me a bit concerned.
The extended period between the oil changes is very convenient -- but I don't want to sacrifice the life of my car.
