I'm on my 2nd tank in my 06 HCH and finding it much better than the first. When I got mine from the dealer, the MPG indicator was at 9.6 MPG and the car had 11 miles on it. I can't imagine what type of tests, etc were happening on the car before I got it, but the FE was horrible. I only got up to 45.3 on my first tank with 500 miles on it when the fuel light started blinking. I'm up to 48.5 on my 2nd tank with over 430 miles on the tank. I have 6 gas bars left too. If it wasn't for the immense amount of stop and go traffic I've had on this tank (and the fact that my wife drove it a bit ), I would be much higher. I'm anticipating somewhere around 50 or so when I'm done. Every trip to and from work it keeps going up and up.
