Clearing Change Oil Message

[pyromedic]

I need to know how to clear the computer message on my 2004 Sierra. I got the message and changed it but the message still comes up upon starting. I have tried to clear it per the owners manual but mine does not have the fuel status computer just the mileage, hours and odometer displays. Thanks for the assistance.

Turn the key to the ACC position, do not start the truck. Pump the gas pedal to the floor 3 times within 5 seconds. The change oil light will flash. This should reset the change oil light.

Thanks, I appreciate it. Also is it best to let the computer tell you when to change or should I go back to the 3k?

If you go by the computer, it does a computation based on hours, speed and mileage. It can come on as soon as 3k miles or go as long as 10k depending on whether you are doing a lot of city driving or highway miles. If you were to go by the computer, I would recommend using a true synthetic oil so if you go to 10k before an oil change, it won't be a problem. I've been going by the computer on both of our trucks. My 'rado turns on every 3k- 4.5k miles because I do a lot of city driving. The Tahoe sees mostly highway use, and is projected to turn on around 10k-11k miles. We changed it out at around 5k. Set your own change intervals based on what you feel comfortable with.

Thanks for the info, I am new to the computer tracking maintainance. Previous GMC was a 94 Sierra 1500 with V-6, Doing the every 3-4k must have been working cause it turned 325k on a steady diet of 20w50 Castrol in 10 yrs of driving with the orig 4.3, and still was not using hardly any oil. Be safe and have a great day.

20W-50?? Wow, I certainly hope that it doesn't get very cold where you are.

Make sure that you're using at least GF3 grade oil - long life designation. This is what Mr. Goodwrench has in his bulk tanks at the dealerships and what the oil life monitor assumes is in the engine. If you're using non-GF3, then change your oil at 3K.

 

By the way, the computer does not keep track of mileage. The input values it uses are ambient temp, coolant temp and crankshaft revolutions.

Can you reset the engine oil light at any time, or does it need to come on first? Just wondering.

I think you can reset it at any time.

Not real cold, we are in the DFW area east side. Went with during the summer the first year and stayed with it year round for the next 9. The miles on the orig block prove it was not that bad of a selection I guess. According to manual I have to stick to the 5/30 or maybe 10/30 in the 04. Thanks for the assistance and information. Now if I could find a way to get some weight in the back of the full 8 bed, responding to calls at 3 am in the rain has taken on a whole lot more excitement than in the 94 xc style side.
