Sorry if this is repetitious, but my new 530i calls for oil changes at 15000 miles or at least every 12 months. As I've always changed oil and filter at 3500, this sounds like a longer period than prudent.
I know the synthetics have changed things, and BMW says they have improved their engines to the point that additional changes are unnecessary.
What are your thoughts?
