I'm told it's considered a maintenance diagnostic procedure, buried in the Service Manual somewhere, along with the three buttons to push on your climate control panel to force an immediate outside temperature update.

Ah, the service manual. I have an old version of GM SPO but as I recall it stops at 2005. I'm down to 1 car that I can still use it for and that's my '05 Grand Prix GXP.
Going to need to purchase a CD or something for the C6.
That worked like a charm. Now all I have to do is remember it. And why isn't that in the owner's manual?
It is. It's called the service only mode. It's basically the same as the "on" on a keyed ignition. Don't count on it timing out and turning off like the Acc mode, so a dead battery is possible.
I searched the 2008 owner's manual for service only mode but it was not found so I searched for all instances of oil life until I found the reset procedure. I does not say anything about putting the system into "on but engine not running". It just says to press the trip button until oil life percentage is displayed then press reset for 2 seconds.
At any rate, I now know 2 ways to reset the oil life monitor.
