I hit 0 Miles to "E" on my way home tonight. By the time I got to the station I planned to used, I had just over 685 miles on the tank. This is a bit better than the previous miles driven record of 680. Commensurate with this is the most gallons added. I hope I never find out the absolute usable capacity of the tank. Assuming that the tank will take 16 gallons when on "E" seems to be well supported. That 16 gallons easily gets me over 600 miles of range and frequently over 650. The initial estimate for the next tank was 700 Miles to "E" when I started the car after the fill.

This tank included driving in Chicago for the weekend and the trip home (over 200 Interstate miles), a round trip to Lansing (150 Interstate miles) and three days of my normal commute (120 Interstate and 30 City miles). One thing about my commute: I have a choice between the route that yields the best mileage and the route that uses the least gas. They are very close, but that is the split on the averages.

2010-08-11 1906 ETA: My 3-tank (41.09, first time over 41) and 5-tank (40.71, first time over 40) averages are also records.
