go to then on new cars look up hummer and select model, you should b able 2 get the fuel economy, or if u want to know the exact link for the hummer h3 click here then for the hummer h2 i have the info, its a 6.0 liter v8,the fuel economy is 12 City / 16 Highway. the fuel tank can hold up to 32 gallons, so ull probably have to spend about 80 dollars to fill the full tank up,these are 100% guaranteed correct answers.

the h1 gas probably gets about 12 or 13, the h2 (suv and sut) get right at 12 for overall mileage, and the h3 gets around 20, with the 5 speed manual and remember the h1 production stops as of today (ends in june) so no more h1’s, only humvees from the h1 plants…mileage also depends on the driver and their driving ways and the regular maintenance of the engine and tires and other fluids

It ranges from 6-11 mpg. My co-worker has one becasue he has a small D!ck.

Are you kidding? If you have to ask then you shouldn’t drive one!

Mileage would not be your first concern with one of those. Get a Honda if you want mileage.

Very poor they are such ponderous beasts

If you have to ask you cant afford it

BESDT BET GO TO GENERAL MOTORS.COM OR CALL A HUMMER DEALER.MOST HUMMER DEALERS ARE ALSO GMC DEALERS.i KNOW THAT H1′S GET ABOUT 10-11 MPG,H2′S GET ABOUT 13MPG,AND NEW H’3 GET ABOUT 15-17 MPG.

If you can afford one,how much gas they use is immaterial

10-12 highway
ouch i know

Consumer reports. It is about 8 highway, 5 city.

Get ready for the pain.
12 City / 16 Highway. This is based on a 2005 H2.
