How do you clear the check engine oil light?
well if it is on a gm???? not sure what kind of car you have. You would turn the ignition on, but do not start the engine. Push the gas pedal to the floor and release 3 times ( push to the floor and let off complety 3 times in a row) That usally clears it. Then turn ignion off and back on and thne u can start it.
