Got a question about oil changes. I have been getting my oil changes done on my 98 318ti every 3000 miles, well I have only got one done and now its getting time for 2nd. I have never had my oil service light come on during my ownership of the car, I have had it since 60K miles and now I am at 67K. The little color bars on the service screen is at a yellow bar now (my inspection light is on, but im not worrying bout that in this post). But today i was reading up on a few websites and they say that the oil service light comes on at about 7500 miles.
My question is: Isnt that bad for the engine? I thought you should always preform an oil change every 3000 miles or 3 months no matter what? Yes, I realize that the oil service computer in the car takes into account driving conditions and such, and not just mileage, but even then, doesnt the oil get old regardless?
