first tank of gas on '07 h3 with auto

When my light comes on it is all I can do to put in 20 gallons. If yours does that, 300 miles would be 15mpg. A bit low, but since it is new it could come up.

Who filled it up the first time? If it was the dealer, they likely shorted you a bit by not topping off.

Hope it gets better, but if it doesn't, it is still a Hummer.

I agree and 15 is only one gallon lower than the estimate. In addition, weather has a direct relation to the fuel mileage.

Good point HumbleAg. I usually have around 330 miles before the light comes on and can usually only put around 20 gal in. Thats about 16.5 mpg. Have seen 19 on the highway and low of about 14. I haven't driven far enough on the empty light to put in 23 gal...
