The check engine light does not refer to oil changes, this is for emmision and fuel management as well as a diagnostic tool for other engine components. The only wasy to clear this is to have the dealer clear them or repair what ever is causing the light. It will however clear it self after about 20 times of starting the car and the computer not seing any more bad scans from what ever caused the light to come on in the first place. You can have Auto Zone pull the codes from your car and tell you what caused the light to come on in the first place. To clear the aoil change light turn the key on and press the gas pedal 3 times all the way to the floor without the engine running.
The fact that the check engine light is on indicates that there is another problem with the engine. I suggest that you have someone with an OBD II reader check the trouble codes stored on your engines computer.
The can also reset the computer to turn the light off when they finish reading the codes.
Or you can disconnect thew battery for about 30 seconds, this will also reset the codes.
Check engine light wasn't on because you needed oil change. have it scanned for codes then advise
