2003 gmc envoy_sle_xl
on mines it took 3 tries and done just dont press it too fast!I've tried maybe 15 times, I followed the forum guidelines, nothing. There is no way I'm going a year without changing the oil to wait for the light to come on, old school I guess. I go about 4k between changes and I never see the oil change light come on except the bulb check at start-up. Normally I take it in to have it done and I assume they have been resetting the light because I never see it. However I decided to change it myself this time because I wanted to put in Valvoline Maxlife, supposed to recondition the seals to stop leaks, I have used this on 2 different Jeeps to cure a rear main bearing leak and it worked both times FYI, I don't have any leaks on the Envoy but at 166k it's only a matter of time. The oil that came out of it from the local lube shop looked like black water, in my opinion completely wasted, and that was only after 4k. So from now on I do it myself. The question is, how do I reset the light, even though it never comes on I would still like to reset it. Will I see some sign telling me it's actually worked, light flashing or something? It's a build date 04-01, SLE Envoy, no info cluster. Thanks for the info.
