Hello, I am a new member who has a problem that I am sure someone has seen before. I am retired and in Fl for the winter. My daughter is in graduate school in Oregon. She has a 2004 70XC which a friend filled up with regular gas after borrowing it. She now has a check engine light and feels the car is running somewhat sluggish. She has made sure the gas cap is on tight and the oil level is OK. She has added a partial tank of high octane fuel but the light remains on. Should the check engine light go out after a full tank or two of high octane fuel is added and miles driven or do we have a larger problem possibly on our hands? Thank you for your help. Russ Dennis
