I averaged 42.1mpg on the computer and 43.2 mpg actual when I filled up with my first tank yesterday. These numbers are very misleading though, as this is my wife's car and she does not know how to drive it well even though I have tried to teach her. I read the hypermiling article and got 64 mpg on th way to work w/o air and got 48 on the way back for a 56 average yesterday. In fact, I probably put 200 of the 466 miles that we got on the tank on and never averaged below 48, with most trips above 50. Not bad for a car just breaking in. We also filled up at two segments left on the gas meter so the gas light never came on. It took 10.8 gallons, so I guess the manuals 1.7 gallons with the light on is a little high if the tank is really only 12.4 gallons. What is everybody elses experience with how much gas you have left when the light comes on?
