SE V6, 2WD. I have now gone 13,044 miles since April when I bought it. I kept fuel log religeously. It has consumed 762.314 gallons for an average of 17.11 MPG. I really expected a bit better. I must admit that I do drive pretty hard. Worst tank was 13.94 towing a 4200# boat and trailer from Atlanta to Lake Oconee. Best tank was the second one when I got 20.12. That is the only time I have broken the 20 MPG barrier. That is probably my biggest dissappointment. IS this about what you get with 6 cylinder and 2WD? Should I be concerned that something is wrong?
