Thanks… So that reset is turning the ignition on, and holding the gas pedal and brake down til the warning turns off, or some other method?The oil change reminder light came on because your car reached a preset threshold of cumulative factors. That threshold is based on various factors like mileage, usage, temperature, time since last reset, etc.
It doesn't "know" that you just changed the oil, until you reset the calculator. Just reset the reminder after every oil change and you should be OK. If you choose to change your oil before the reminder comes on, that's fine too. The reminder light will be a good failsafe if you forget.
