I'm doing my first one at 1700, only because I plan on taking it to the track and I'm kind of in old school mentality on the first oil change. After that I'll follow the computer, although with my limited driving it will probably hit the one year before the computer says it's time.
Trying to decide which oil. I'm pretty sure I'll stick with the regular Mobil 1. There are so many oils anymore. I don't mean brands, but extended life, +, ultra, etc. They all have the Dexos rating. Can anyone tell me if it's worth it to go with their "premium" product? The money is no big deal, it's only a few bucks. It seems to me that most of the few extra bucks you pay is more profit for them from marketing than a much better motor oil...
