OLM: Got one but is it right

No one has shown a GM UOA where the OLM has been "wrong"; I'm sure they put a lot of development into it and also a good safety margin....
Do you trust all the other computer systems on your vehicle?
They puts lots of research into them and if they were not any good they wouldn't have decided to put them in the vehicles.
Most modern vehicles have OCI's higher than 5,000 miles anyway.

Hi,
Petrou - IME if you use the correct viscosity lubricant that is Approved for your vehicle - you can "trust" the OLM

If you use cheap oil then it's probably very accurate
A consensus on BITOG!!!
Do new GM/Chevy vehicles with OLM on them actually have oil change intervals or is it okay for warranty purposes to just change the oil when the OLM says too?
If for warranty purposes you still have to adhere to some strict schedule what is the purpose of having a OLM?

The owners manual of my 04 Silverado and 01 Grand Prix do dot list a OCI they only say to follow the OLM.

Bingo!
IMHO OLM's are proving to be pretty darn trustable.

There might be a limit of 12 months or something but typically the manual says to go by the OLM if you don't exceed the time limit.
That's good advice. 12 months or OLM.
I'm sure they check the OLM to see mileages and resets if a warranty claim ever did arise that was oil-related.

Sure they can, but don't take anyone's word for it. Prove it to yourself. Just do a UOA with taking it ONCE to zero (or below 10%). Then adjust your pucker factor accordingly. We've seen, iirc, everything from 3k-13k puked out of the things depending on the type of service they see.

OLM doesn't keep a history. Once reset it will clear out the data previously stored.

That's a surprise. I would think that it would be very simple (and not require too many resources) to keep a permanent record of OLM reset state readings.
For warranty keep the oil change receipts. Mr Goodwrench could come back with "Just because the OLM was reset doesn't mean the oil was changed".
GM dictates OCIs through the OLM or once every 12 months, which ever comes first.
One of the last studies I've read had one of the engineers quoting an average drain interval of 7500-8500 across the GM fleet. I've seen as low a 3300 and as high as 12800. All depends on the vehicle, engine, and its operating environment.
While I am still on the fence about following mine, I can say that I have NOT seen a UOA to support any of my concerns.
