Ignore the dealer on this topic. Why the frequent oil changes at 4.5K?

Well if the owner?s manual states to change the oil every 3,000 miles and you don't... GM will void your warranty. At least that's what I've heard.

Not what the Hummer H3 owners manual states. Please read again.

My owners manual says to change the oil and filter when the DIC says to, or at least once a year. 3000 miles only if you accidentally reset the monitor. Next time, I'll probably change my oil with 25% life left, but that's just me.

If GM says you can trust the oil monitor, the dealer can't say different. They have to honor the GM written warranty, not the dealer's opinion.

If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.

There is no specific line in the manual that I can find, but I do see that they indicate 3K and my dealer always adds 3K to my current mileage for my next oil change. So what have you got that is different?

Yep, I read the same.. What if you're on a 700 mile road trip and your DIC goes off at mile 200 and it's 1am in the morning?

So you read that as needing to do your oil changes at 3K miles, right?

Wrong, what the dealer is doing is allowing any suckers that believe their BS to help them to increase their revenue and profits.

If you haven't changed the oil for 7000+ miles and the DIC hasn't gone off yet, and you are about to go on a long road trip, get the oil changed before the trip. Plan ahead, it helps.

Yeah, it's tough being programmed all your driving life to do an oil change at 3,000 and then now 7,000. I guess that's my problem.

I'll stick w/ the OnStar recommendation and begin to use one of the Trip odometers to regulate.

Here's another question... do you tend to go through oil faster on long road trips or on 30-40 minute stop and go commutes?

Stop and go wears out the oil much faster than highway driving.
