Same goes for oil life percentage, just had my GM dealer service mine and they didn't reset it. Wonder what else they didn't do?lloger said:Have the 'average fuel economy' showing on the DIC and hold down the button with the arrow on it. The button is on the left side of the steering wheel.

No time frame, I did mine two days after dealer serviced it. Guess that's a two day time frame?wildcat66 said:I will try again and I have tried it both ways! The dealer forgot on one change but did it at the others. I wonder if there is a time frame after the oil change that it can't be done???
