Ya my buddy Larry has a 2006 air with a 6 inch lift and a supercharger and still gets 10.3 with his. I have the 2003 suv and I'm getting 11.9 with a stock unmodded engine. I am thinking about supercharging mine now. Kissing roughly mile and a half a gallon for all the extra power seems worth it.

 

im getting about 8 with the setup in my sig. im looking for a superchip or something to adjust the speedo and give a bit of tune to go with the exhaust.

For the record. I hate the combination or auto spell on my phone with the effects of Percocet. Makes it look like I am a 12 year old kids that can not spell. I really am sorry about that
Steve a supercharger might actually help your mileage at this point. Although your duece is what, 9 feet tall with 200 lbs of wheel and tire at each corner. I'm willing to bet the extra power from the charger would compensate enough to save you a mile or two. Larrys isn't much lower and he gets over 10 all day.

 

With a stock everything except a full Gobi rack with the tire on the roof (which I'm sure doesn't help matters), I can avg between 12-13 MPG per tank if I don't get on the highway. If I'm on the highway, it drops to 10 MPG.
My non-highway driving isn't exactly stop-and-go though. Mostly two lane roads running 50-60 MPH.

 

I did post before but after a couple long trips ( 700 miles round) I get better idea of what MPG im getting
700 miles all Highway --- 14 MPG
City-miles (soft foot)--- 11.5 MPG ( notice I live in high traffic volume city )
City miles ( hard foot ) --- 10 MPG
Highway miles with trailer ( jetski) ---- 11.5 MPG

2006 H2 unmodified . regular fuel

 

Talking about gas.
Never eat more than 239 beans before entering a hummer.

















Otherwise it gets too farty
Sorry could not resist.

 

Getting about 12mpg in town with 35's, CAI intake and my own tune in HPT to compensate for the CAI. In the winter, I get about 9mpg.

 

good to know, ill have to start looking at them soon. I was just looking for a tuner mainly for the tire size and to give a bit of a boost with the exhaust.

its alot easier to spend 350-400 on a tuner instead of 4000 on a charger lol

Unfortunately, Here in the NorthEast, I can't get non-ethanol blend fuel and my milage has really gone down.
But my wife doesn't drive her H2 much anymore. We have done the east/west/east loop and it is unbelivably comfortable! She may be doing the trip again this year to help out her parents in CA.

We just took a mini-vacation to MT in my V10 F250 to pick up a 25' 5th wheel camper trailer. Saw the low end of 14mpg at times on the way out (I normally get around 9 with my short slow work commute). On the way back using the option to fill with non-eth. fuel milage slightly up (trailer was 8-9000#) Low was 7.4 to almost 11.5. With alot of long down grade in PA it bumped up to 12.4! I wish I had the 32 gal tank from the H2 instead of the 26!
I'll be doing a tune up, brakes, shocks, airfilter, outer tie-rod ends replacement and maybe a hub replacement before she goes.

Your sig is awesome,i also would like to get myself an H1 one of these days.
As far as this thread,i'm pretty sure everyone knows how much Hummer mileage goes but i know most of you would agree that Highway MPG is the best when going at 60-70 mph flat.

I went down to Tijuana one weekend and didn't spend nearly as much as i expected to. My MPG at 65 mph was aroun 22-24mpg which was awesome!
The only issue is in-town driving lol...
