JIM165 asked about my oil history: I typically only changed the oil during the standard intervals, but the car burned about 2 quarts every 5k miles so I was always putting oil in. In the end the oil usage was going up and up and up.
But from reading a few posts on here it sounds like BMW's best practice of an oil change every 10k miles is risky and can hurt engine and parts. I can see how this would be true especially with BMW owners. I imagine most of us are more lead-foot then other kinds of drivers.
