My last refill occured - I'm not making this up - at exactly 16,000 miles. Since I drive with ODO1 showing to let me know how many miles I've driven on a tank, I did not know the cumulative mileage until I entered the "tank miles" into my spreadsheet and saw that the total miles calcualted to exactly 16,000. If you want the graphical representation, click the link in my signature. Averages so far: Total Gallons => 328.87 Total miles / total gallons => 48.6 MPG Days between fill-ups => 13 Gallons per refill => 9.135 My 1998 Buick Regal averaged 20.68 MPG (Feb - Aug, 2004) 16,000 miles would require 773.7 gallons A savings of 444.8 gallons of gas (more than I even consumed) Yes, I love this car.
Awesome chart Tony -- too bad the MPG is so tied to the outside temp -- it's pretty cold already here in MN!
