When I look at your mileage I can't help but wonder why some car manufacturer does not at least offer an aero option for those that want it . You and CO ZX2 as well as a few others have demonstrated convincingly what simple aero changes can do. These are not high tech changes that would cost $3000 per car. These are straightforward understandable things demonstrating the effects of aerodynamics.

The hand throttle has been a great help in getting better mileage at lower speeds where the throttle/mpg sensitivity gets very delicate. Altitude also helps, as I can get somewhat better mileage at 2000ft on I-26 in the NC mountains than I can at similar speeds and temps at 700 ft in the SC upstate (I wonder what sort of mileage I would get if I were driving at 10,000 feet). I have a steep 800 foot climb up into the NC mountains on my way to work and I am only getting about 1/2 of the energy back via FAS coasting that I put into elevation gain while climbing up the mountain. The rest is lost via engine and friction braking. This tank had more urban driving than I usually do.
I just did 510 miles on 11.126 gallons - broke the 500 miles on a tank record trying to be reached by a bunch of xB guys in Scion Life - prior highs were 480-490's with 12 gallons in an 11.9 gallon tank.
I did a lot of engine braking on this past tank - 3 weeks of driving and found that the ScanGauge error was getting up to a significant error. The low fuel light came on at 10.7 gallons and usually it is pretty consistant at 10.0 gallons and it took 11.126 to fill yet indicated I burned 11.5 gallons.
