Changing Oil Life Mileage Setting?

[Cesardajr]

Does anyone know if you can reset the oil life system to indicate a oil change is ready at 4K miles instead of the 5k miles?
i think 5k miles is too much based on the look of the oil when i change it out.
im running mobil 1 with the same filter.
Thanks

NO, you do not need to. The OLM is based on a algorithm of things such as average engine speed, running temp, starting temp, average trip time, and so on. These are very accurate and GM actually states the average trigger is 7500-10000 miles.

BTW: There is no way you can judge your oil by the look. Unused oil in an open bottle will darken with time.

I was thinking it was not a true 5000 miles either.
Since it does depend on factors like driving, towing ect,
have you thought of doing an oil analysis to determine
if there is any need to do early changes?

If you want an oil analysis, take a test tube amount to your local general aviation maintenance facility (FBO) at an airport and they can do it for you. Make sure you use some container that has a screw on lid and is air tight so your oil sample does not oxidize or hydrolyize. The less air in the container the better. I had one done in 2006 and it ran $157.

AT 157.00$ I Just replace the oil, and no need for O.A. unless you can get it for less that the price of oil and filter.....

thanks, i know how to reset the oil life, my question was there a way to make the oil system indicate a oil change is needed at every 4000 miles only.

CHANGE OIL SOON INDICATOR

2003 H2

1. The Oil Life System will show when to change the engine oil and oil filter. This will usually occur between 3000 and 7500 miles since the last oil change. Under severe conditions, the indicator may come on before 3000 miles. The system will not detect dust in the oil. Reset the system when the oil has been changed.
2. To reset oil life system, turn ignition ON, with engine OFF. Fully push and release the accelerator pedal slowly 3 times within 5 seconds. If the CHANGE OIL SOON light flashes, the system is resetting. Turn ignition OFF. Start engine and all to idle. The oil life will change to 100 percent. If the CHANGE OIL SOON indicator comes back on, the system has not reset. Repeat the procedure.


Wait a minute we have a 2003 and ours resets with the steering wheel
controls just like the instructions you gave for a 2004?
