I seem to get 21-22 MPG consistently on long trips that include mostly freeway mixed with some city & county roads. I recently reset the MPG readout on a short freeway trip and got 26.3 MPG on 40 miles of fairly level freeway averaging 65 MPH. In the city my mileage varies from 13-15 because I don't drive very far on most trips. My work commute is 3 miles so it barely gets warmed up.
