Can mixing gas cause engine light?
Accidentally pumping regular 87 octane gas into a car that requires 93 octane may cause the ‘Check Engine’ light to come on. Vehicle computers can compensate for less than optimal octane by reducing ignition timing.
Why does my check engine light keep coming on?
That being said, there can be several reasons behind check engine light due to the gas cap failure. If the car has run for a considerably long time, say 50,000 miles with the same gas cap, it’s safe to say that the reason is your gas cap is old, weary and exhausted. It will let pollutants find their way to your fuel chamber, clogging the filter.
Why is the gas cap missing from my Check Engine light?
The cap is not in place or securely sited. The cap is completely disappeared or missing from the car. The cap cannot close properly due to grime and mud near the opening. The gas tank is out of shape due to an accident, putting extra pressure on the gas cap.
What should I do if my gas light comes on?
If the light comes on, Mazor suggests the driver should check the gas cap. A loose gas cap sends an error message to the car’s computer, reporting a leak in the vapor recovery system, which is one aspect of a car’s emissions system. If the fuel cap is loose, tighten it and continue driving.
Is the service required light the same as the Check Engine light?
Some drivers may confuse the service required or maintenance required light on the gauge cluster for the check engine light. These warning lights are unrelated. The service required light just means the car is due for an oil change or other routine care. It is not an indicator of trouble like the check engine light is.

What to do when service engine light comes on?
If you are 100% certain that the service engine light came on for a loose gas cap or another minor issue, you can reset the light yourself. In order to start the process, you have to dismantle the service engine light in your car. You can either use the scanning tool or you can disconnect your car battery.
