not that great....  no
 
I get 11.7....now.... up from 11.5 this summer....
 
but then again you said it's only got 12,000 miles.... so drive it a little and see if that average goes up...  or set the cruise for 65 and see what the instant reading is....
 
 
 
 

If you want to improve fuel mileage you can get the superchip(or PCMforless) for the h2 and it should give you a 2mpg increase. Free up the engine withan intake and a new muffler and you should be getting around 13 to 14 mpg or higher.

and another thing.... you just got it... so I know you're not pretending you have an egg between your foot and the go pedal....

10.5 is the norm for me.  11.5 if I'm easy on it and tahe the express way home.

I would be horrified.  I averaged 15.3 on my stock 03 last night to work and back.  60 miles round trip combination of 55 hwy and back roads.  Overall in the 10k miles I've driven it, I've averaged around 13.5 and about 25% of the time I'm pulling a 5x8 enclosed trailer.  I will say this.....I found I get about 2 mpg more using BP fuel.   Good Luck

i agree with Gorillah2.i was doing about 10.0mpg i went to about 11.3mpg after my volant intake and my hypertech programmer.exhaust is commin next.

Please Bob....tell me you're kidding!!!

and get some magnets... I hear they are the bee's knees....
 

the magnets are awesome.  i put them on my frame on either side of my transfer case and went from 8.35 to 8.351 mpg overnight.  the magnetic field generated by having them on opposite sides of the transfer case creates an air buffer that eliminates drag from the transfer case skidplate, allowing you to almost hydroplane on pavement.  it's awesome, i'm so glad bob let me borrow them . . . . . . . .

I also have noticed that I get better gas mileage when I am going downhill.....  dunno why.... and no one seems to be able to explain it.... but I have seen 60mpg or better...

Thsoe things are complete bull because I used it on my hummer and it actually decreased my mpg by 2 miles. They are worthless

you put it in backwards.....

I probably did

Do these Things really work???  Seems like a bunch of BS to me.  Anyway  I  get 11.3mpg  But mine might be off because I have 37's.

Garrett, that's a HUMMERGUY Joke!!!

Seriously, I was getting 10.5 - 10.9 till I added mu Volant CAI and Magnaflow Exhaust. Admittedly, I added the exhaust cause I wanted the DEEP GROWL that we SHOULD get with a 6.0l V8 but didn't. And I did the Volant cause I thought it was COOL!!!(yeah...I'm not much of a gearhead!!)
 
Anyhoo, I usually get 12.5 - 12.9 city in the summer and that's driving it like I stole it. I KNOW it's not a sports car, but i LOVE givin' er off the line and hear my exhaust SNARL!! I'd probably be getting better MPG if I drove it SOFTER!!!

Gas mileage depends on elevation, air temperature, etc. So while one guy gets 15 mpg on the highway (maybe in Canadian gallons on the flats), likely not in US gallons. They ARE VERY DIFFERENT gallons.

Air temp and elevation play drastically with gas mileage. So does terrain (slope). So 9.5 mpg is OK. 15 mpg is OK.

Oh, who cares. If you do, go buy a Prius.

And last, the turbulence intake generators do not work. Do you think they actually do. Duh. If so, don't you think GM would use this 50 cent piece of metal to raise the fleet fuel average by 2 mpg. That is HUGE! Like 20% better gas mileage on an H2.

Save your money, and buy more bling instead !

Inside JOKE!!

averaging about 10.5. intake, exhaust wil def help. they do on any vehicle. havn't gotn tht far wit my h2 yet, but ive got experience with other vehicles.

Averaging about 12mpg city on my 2003 H2.

After my H2 gets out of the shop I have to finish setting up some things and I should be getting 15 to 17 mpg

lol you know what could work get a hybrid and drive the h2 on weekends only you will see the saving  your lololol

thats silly
