TIP: GM Oil Life System - How to reset Change Oil Message

GM Oil Life Systemâ„¢

Press the reset stem until OIL LIFE appears (flashing) on the display. The GM Oil Life System™ shows an estimate of the oil’s remaining useful life. It will show 100% when the system is reset after an oil change. It will alert you to change your oil on a schedule consistent with your driving conditions.

Always reset the engine oil life after an oil change. To reset the oil life system press and hold the reset stem while OIL LIFE is displayed. The system will reset and a beep will sound.

The DIC does not replace the need to maintain your vehicle as recommended in the Maintenance Schedule in this manual. The oil change reminder will not detect dusty conditions or engine malfunctions that may affect the oil. Also, the oil change reminder does not measure how much oil you have in your engine. So, be sure to check your oil level often. See Engine Oil on page 5-13 for more information.

Owners Manual Page 5-17
How to Reset the CHANGE 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 CHANGE OIL message being turned on, reset the system.

Always reset the engine oil life to 100% after every oil change. It will not reset itself. To reset the CHANGE OIL message, do the following:
1. Display OIL LIFE on the DIC.
2. Press and hold the reset stem. The oil life will change to 100% and a beep will sound.
3. Turn the key to LOCK.

If the CHANGE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure.
This is from eSI and is more accurate and detailed than the Owners Manual.

For the oil life system to work properly, the system must be reset every time the oil is changed.

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. The change engine oil light will come on. The oil must be changed as soon as possible. It is possible that, if the vehicle is driven under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. If the system is ever reset accidentally, the oil must be changed at 3,000 miles (5 000 km) since the last oil change. Remember to reset the oil life system whenever the oil and filter is changed.

1. Turn the ignition to RUN with the engine OFF.
2. Press and release the reset button in the driver information center (DIC) until the OIL LIFE message is displayed.
3. Once the alternating OIL LIFE and RESET messages appear on the DIC display, press and hold the reset stem until several beeps sound. This confirms the OIL LIFE system has been reset.
4. Turn the key to lock. If the CHANGE OIL message comes back on when you start the engine, the ENGINE OIL LIFE system has not reset. Repeat the procedure
Alternate Method
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal 3 times within 5 seconds. Several beeps sound. This confirms the oil life system has been reset.
3. If the CHANGE/OIL message comes back on when you start the engine, the engine oil life system has not reset. Repeat the procedure

Hmm I have been trying to just check my oil status.....I turn the key to the "on" position and press the button until "oil life" appears and is flashing. But I can't see what percentage of my oil is used up? Where does it show you? all I can see is the mileage. Any suggestions?

It won't tell you a percentage except when you reset it. It will only tell you when it needs changed.

A little arrogant of them!

I am told that the on-board computer can calculate and store the percentage of oil life, but for some reason we got shorted on the display.

the dealer can probably tell with the diagnostic tool, they just don't show the consumer.

I can press my stem until I'm blue in the face. All it will do is toggle back and forth from my odometer to my trip odometer. What am I doing wrong?

Something that tripped me up for a while is that you need to have the parking brake off, as well as all the doors shut to be able to access the oil life reset. Any messages displayed on the DIC will prevent you from getting to the oil life portion.

Oil Life display

I also can't get my oil life display to show the percentage of oil life left. The owners manual leads you to believe that you can check the remaining life left. I've got almost 10.000 mi on mine and the change oil message never came on. I did however change the oil at 6000 mi and I'm getting ready to do it again in a couple of thou mi because I've always been a advocate of frequent oil changes and I'm not going to wait for a computer I dont trust to tell me too. I didnt re-set the oil life when I changed it because I want to see if it ever comes on. I've been using Mobil 1 for the past 7 years or so in my past vehicles and I know you can go longer intervels but 10,000 (mostly highway miles) is still my limit.

Nowhere that I could find mentioned doing a first oil change withen the first couple thousand miles like I've always done in my past new vehicles. Whatever happened to "getting rid of the break-in oil"?

They don't recommend removing the breakin oil that early. They haven't for a few years.

Also the DIC will not show the percentage left on our trucks. The manual for the 2004 models had a mis-print.

Owners Manual Error - Oil Life Percentage Displayed on DIC - kw GMT355 display cluster indicator #PI01834 - (03/04/2004)

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
Owners manual states the DIC will show oil life percentage. This is incorrect. The DIC will display oil life when the oil needs to be changed. It will never show oil life percentage.

Recommendation/Instructions:
The oil life can be reset per the owners manual with the DIC. Or it may be set with the Tech 2. To use the Tech 2, go to PCM, special functions, engine output controls, oil life reset. You can see oil life percentage and reset the oil life at that screen.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.

Models:
(2004 Colorado Canyon S1 T1 GMT355)

Oh wow- so the dealer can retreive the oil life percentage before clearing it !?!?! I wish i would have known that on my first oil change. I had it changed before the change oil light came on.

exactly my thought. I'm going to have it checked when I get 7000 miles on the oil this time. That is when I changed the mobil 1.

I've been trying to get the CHANGE OIL to stop flashing for two days now after reading all the posts on this site. Still will not stop. Is a trip to the dealer needed to correct this ? What about disconnecting the battery ? Will that reset everything ?

OK OK I finally figured it out
I was just pressing and releasing the reset
switch once and you need to do it three
times to get OIL LIFE to appear then you
can hold switch in until the beeps are heard.

You will not hear the beeps if you changed your headunit and are not using the Metra VT-GMRC-01 harness.

I tend to ignore the oil life crap thing. I just change my oil at regual intervals. You drive your truck and know when to change the freakin oil. I think GM put it there for the women who dont understand the concept of an oil change or even know if thier particular vehichle requires oil.

There are plenty of males out there that don't know squat about engines and the care and feeding of them.

Women for the most part would rather charm a man into getting oil and dirt under their fingernails than grub up their own. Who is smarter here?

I've been getting outsmarted by women for many years.

Any motor-heads correct me if im wrong, but I believe the GM oil life system measures engine revolutions and precise temeratures as well as miles and calculates the percentages from that, so if someone is a grandpa-driver, then at 7000 miles, the revs will be lower and oil use may not be that low compared to someone who has their foot in the tank may burn through the black stuff in 4k miles.

Personally, unless you are running synthetic, 3000 miles is solid rule of thumb for city folk like me and 4000 for less severe conditions. My resoning for that is that why would you want your engine oil to be 100% spent for any length of time before changing it? The real reason people push their oil changes back is that they dont want to spend the money and time on something you cant immediatley see a benefit of doing. I dont care who you are or what you drive or what oil you use, 7000 miles is a stretch.

back to the gm oil system: when i ran jiffy lube, i saw these systems 2-4 times a day and if the change oil message was on, the old oil came out dark, *not black* mind you, but good and spent, about when my cadillac showed 20% oil life left (for example), or about 2800-3200 miles, or 3200 to 3500 miles in winter. Ive run it to 4500 miles and it ran fine, just about a 5% loss of mileage after 3000 miles, roughly, but again, why ever run on spent oil? doing it yourself, an oil change shouls cost less than 15 bones, or about 20ish at a reputable garage. Damn, just change it.

The mechanic told me the computer calculates things such as miles, number of times the truck is started and such. He said it is not a very accurate way to tell if your oil needs changeing, he still recommends every 3000 miles.

There is no such thing as stupid questions, just stupid people asking questions!
