Worst MPG ever. The Sonic sucks gas and I'm ready to get rid of it. 28mpg is the highest I've ever gotten. Engine light on all the time but can't find a problem. I believe there is a problem and it's affecting the gas milage. The MPG won't reset so I'm not sure what I'm getting but I'm putting gas in constantly and I drive very little. Bought the car with 1600 miles and now after 16 months the car is at 7700 miles. That should tell you something.Report it
