Hi, just discovered the site and have been having a blast reading the old posts (when I should be studying for midterms).
Anyway, question is whether there's any benefit to using the expensive fuel injector cleaners vs. the cheap bulk stuff I can pick up at Wal-Mart (a 3 pack of STP is just $6) on my 2003 Alero, 3400 V6?
My second question is, how much faith do you guys put in the on-board computer in telling you when it's the right time to change your oil, for those that have that feature. I'm 8500km past my last oil change but the oil still looks fairly clean.
Thanks
