I was talking to someone who owns a newer...(00-03?) bmw station wagon, and they said that the service interval for oil change is 15,000 miles. That seems incredable to me....anyone know more about um?
i dont know if that is what the manufacter claims, but with 100k tune-up and coolant change intervals it wouldnt surprise me. But, i bet they use synthetic oils, and that oil change interval is only good for what they call ideal conditions :? . which in the real world is nearly impossible to achive.
And after doing thousands of oil changes in my career, most of those oil filters welded on pretty tight. Thats only after 3000 mi. Ever have to air-chisel an oil filter off? I hope your friend never has to.
