Run ethanol free gas, your mileage may increase. I have had good luck with Seafoam for keeping my fuel systems clean.

I get 22% better mileage with ethanol free gas. Your car engine was EPA certified with ethanol free gas, not the gasohol junk. The mileage numbers published for your car are invalid if you do not use ethanol free gas.
