Q10116 - INFO: GM Oil Life System Warning

Your GTO has an Oil Life System incorporated into its computer.  While the computer thinks it knows when you should have your oil changed chances are you use the motor as it was intended.  So we recommend that you check your oil often and change it every 3,000 miles depending on driving and racing habits.


This is the reset info for that system, which is located in your owners manual.

How to Reset the Service Engine Oil message

The GM Oil Life System calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
Service Engine Oil message being turned on, reset the

After changing the engine oil, reset the system by
performing the following steps:

1. With the engine off, turn the ignition key to ON.

2. Fully press and release the accelerator pedal slowly
two times within five seconds.

This is an error and really should be press and
release accelerator pedal slowly three times within
five seconds.

3. Turn the key to LOCK.

If the Service Engine Oil message comes back on
when you start your vehicle, the engine oil life
system has not reset. Repeat the procedure.

Thank you! Worked on first try. Approved: 8/5/2008
I read the GM book. I must have tried to reset the computer 100 times or more. I found this site and read how to properly reset the computer. You would think GM could send out a notice that the book was wrong. Approved: 8/4/2007
Im still having trouble getting reset to work after changing oil Approved: 8/4/2007
my service engine oil light was on and i didnt get a manual with my car thank you very much Approved: 7/18/2007
Thanks. I was going nuts trying different combinations of clutch in or out, trans in gear or neutral, varying speed of depressing and releasing the accelerator, etc. I was very glad to find this very direct and simple correction of the manuals procedure. It worked the first time I tried it, eliminating that annoying pinging alert at every startup. My first alert was a couple of days ago at about 9,300 miles. I had already had one change at about 4,500 miles, but changed it again today. With my driving habits of only occasional hard use, Mobil One helped keep my old 97 WS6 Firebird running strong for 10 years with regular changes every 4,000 to 5,000 miles. Approved: 5/21/2007
Told me what I needed to know about resetting the oil monitor. Changing oil every 3K miles is questionable, especially with fully synthetic oil whose rated life is as high as 25K miles. New oil is rough until it is broken in, changing it too often will actually wear the engine more than changing it less frequently. 5K is a good number, but of course that lowers the profits of the dealer selling the services and the oil makers selling the oil. So I do not expect much consensus on my philosophy. Approved: 4/24/2007
Sitting in the car today doing the two times 5 sec push and wondering why, thanks for one less thing to think about :) Approved: 3/30/2007
thanks worked first time i tried it Approved: 11/5/2006
Why useful I dont like the personal opinion. The oil life monitor takes into account "How you use your engine". Also since a lot of us use Synthetic I dont have any worries about following the recommendations of the oil life monitor with synthetic in the pan. You may also wish to mention as stated in the manual that the sysem can not take into account dusty conditions so in that particular case I would agree 3000 mile changes are warranted.
