Rick, and anyone else with similar qualifications:

My 2004 GMC 1500 has an oil change light and a computer that tells me  
what percentage I have left on my oil life.  At 4300 miles since my  
last oil change, it still says 47% oil life remaining.

We are using regular oil, not synthetic.  This is my tow vehicle but  
it only tows about once a month (to keep this endurance related, this  
is because I have local trails for training and can only afford to  
compete once a month).  It is also my commuting vehicle so it travels  
80 mi per day, 4-5 days a week.

Should I believe the truck's computer, or should I believe my very  
trustworthy mechanic who swears by changing the oil every 3000-3500  
miles?  If I sided with the mechanic, I'd be changing the oil every  
month and a half or so.

Thanks,
Sharon L. in Maine
