Hi I got a question about the oil life monitor feature. I have a Buick which also has this feature and when I reset the Buick's after an oil change the indicator light flashes to let me know it has reset. As mamy times as I try to reset the GTO I never get any type of reaction from the GTO letting me know that the system has reset itself. Does anyone on this forum know if it works the same as other GM vehicles? There doesn't seem to be anything in the owners manual about this other than how to reset the computer.
