It's not a freaking Tercel !



BMWs have a computer that calculates your oil service and inspection (minor and major service, respectively) intervals based your driving habits. Porsches may too, I don't know. It cuts down on unnecessary oil changes. Disregarding it and using a "one interval fits all" schedule is just throwing money away.

If you're using expensive synthetic and a good filter, there's nothing wrong with extended intervals; why throw away perfectly good oil. I had my oil analyzed with 5k intervals and they suggested extending it. I use mobil 1 synthetic and filter and now change it every 7.5k miles.
