Question about 2002 Jeep Grand Cherokee
I had the same problem. I noticed a small beak in the rubber gasket on the gas cap. I bought a new gas cap and the problem went away.

What is the code? Could simply be a loose gas cap setting the light off. If the light goes off after several engine run cycles, it's not a consistent problem. Blends may affect performance but shouldn't hurt the vehicle if you are using the correct octane. Your owner's manual defines the required octane.
Some parts stores scan your vehicle for free in hopes you'll buy parts to correct whatever the code is. Be careful as codes mean more than 1 thing usually. Get the code from the store and post from there.
