Alright so I changed the oil in my truck and after about 700 miles the
change oil light comes on when I turn the truck on but goes off after
about 10-15 seconds. Anyone know why this is happening?

Maybe it did not "take" the first time. Repeat the instructions in the manual and see what happens and be sure to press the pedal fully to the floor with the ignition in the on position. Right now your vehicle is behaving as if it was not reset.

i agree with jimbo...i woudl repeat the reset process...

after changing the oil you must turn the key to the run position and press the gas pedalto the floor three times kind of quickly this resets it otherwise it will drive you nuts. please let me know how it goes thanks.

To follow Frankies321, If it takes, you should see your IP oil light flash quickly several times. If you do not, try again. If you still have problems. Drive by a dealer or garage. They will be more than happy at no charge to assist you in resetting it. Just remember what they did.....

I have a 99 Silverado
I was told to turn the ingnition to ON then quickly press the pedal all the way to the floor four time and on the fourth time hold it down for 10 sec. it works for me
