I drive a 2003 Mitsubishi Galant with approx. 58,000 miles. I've always used mid-grade or premium gas but a visiting relative wanted to fill my car but did'nt ask what I used . Needless to say they went the cheaper route and filled it with regular. After a few hours of driving, the engine light came on. I checked the owners manual and re :( did the gas cap as it suggested but the light is still on. Could the change in gas be the problem and if so when I take it to be serviced will it cost me my first born child?

i dont think that the switch in gas is doing any harm but it could have possibly clogged one of the sensors....my recommendation is to run to the store and buy a code scanner for your car it will cost around $50 but with the newer cars it will become of much use later on and you will be happy you haveit..... once you get the code come back and post it and we can help further.... good luck :)

I agree....buy it, use it and return it the next day. post the code and we will help you find your problem...sometimes disconnecting the battery for a minute will reset your check engine light...it works on my 98 Eclipse when my sensors go bad, of course if you dont fix the issue first it will bring the light back on.

Suggested Repair

Read the check engine light with an OBD-II code scanner and use the code for further diagnosis. A switch to regular gas is unlikely to be harmful, though a sensor fault is possible. The gas cap was already checked. Disconnecting the battery may clear the light temporarily, but it will return if the fault is not fixed.

Conversation Summary

The owner of a 2003 Mitsubishi Galant with about 58,000 miles normally uses mid-grade or premium fuel. After a relative filled the tank with regular gas, the check engine light came on and stayed on after the gas cap was checked. Experts said the fuel change was unlikely to cause harm but a sensor could be affected, and advised scanning for the diagnostic code before further repair. A battery disconnect may reset the light only temporarily.
