My friend has an envoy with all these computer motor monitoring systems.....and he ended up having a lot of problems with it because the computer let him drive more than 20 k miles. Some was under warranty, other repairs were not.

My advice is spend the $ 30-40 dollars and save your engine plus all the hassles of the dealer refusing the warranty....my opinion.

How do you access the remote diagnostics?

New 2008 H3 with 1260 miles on it and the OnStar report just said oil was at 82% with a predicted oil dump at 7400 miles.

Working for a Major Transit System, we do oil samples at 4500 miles to see what the oil condition is. Many gasoline engines start seeing more metal in the oil after 5000 miles. The new semi-synthetics have better lubricity through the 7500 mile mark as long as the conditions are not too severe (AKA extreme cold / short trips, extreme heat / long trips, dirtry dusty environment, Marine salty environment)

My higher compression engines really carbon up the oil early so they get changed @3,000-4,000 miles.

I get the onstar reports and look at the status. However I use synthetics and still change regularly about 5K miles...

Has any one discovered the remote diagnostics yet. I found it. Then I accidentally reset the oil life monitor. I instantly got an e-mail notifiying me that my oil was changed and was at 100%????

I'm going by the GM Oil Life System.
I had the same thing on a BMW. Average oil change was around 15,000 miles.
I figure that the manufacturers, who have to fix problems for free, under warranty, know best.

Default Re: Anybody going by the GM Oil Life System?

I use Castrol Synthetic and change every 3000 miles. Old school I was brought up that this is the thing to do so I do it. I've never had bearing or ring or seal problems in any vehicles I owned so I think it's a cheap investment.I kept one car 16 years and the motor was still great when I got rid of it.
