Does anyone have any suggestions (K&N, Cold Air Intake, Chip) on how to get a couple of extra miles out of a gallon of gas....getting about 10.8 now...would like to get a few more if I could.

Buy a Prius!!!!

Seriously, alot of companies MAKE CLAIMS about improved MPG!!!! Most of them are BUNK!!! 1st off, once your Rig BREAKS IN some more, you should see an increase. I'm getting 11.5 now, should be up to 12.5 in the summer. Winter always bites letting her warm up and all.

I did get the Magnaflow Exhaust and the Volant CAI....mostly for increased RPM's(TOTALLY worth it

), but I'm sure if I didn't drive it like I stole it, I'd get better MPG

Like Bob said, get a Prius :-) If gas mileage is a major concern to you, you probably need to consider a different vehicle. The H2 is big and heavy and with the resulting thirsty engine ... As far as CAI's and catback goes .. if nothing else they will lower your gas mileage ... can't make more horses without more O2 and fuel ... and quite frankly ... those two products carry a certain right foot factor as well ... hehehe
In my opinion gas mileage is not really THAT bad considering weight and engine size. My old RAM SRT-10 averaged approx 8-8.5 mpg between city/hway and in comparison my H2 is damn near an economy vehicle squeezing out up to 13 mpg on the freeway ... it is what it is ... not a vehicle for fuel concious people!

Well said, anybody with a H2, MPG just isnt in the Equation!

I am not too worried about the gas milage...I mean who really needs to eat anyway...I can spend the extra money on gas. I guess my biggest problem is I still drive it like my 300....0 to 60 as fast as possible...might take awile to get to used to driving a Hummer after all this is my first experience owning an Urban Assault Vehicle.

You can always go with a tune, catback, cold air, headers .. and if you want to get real funky slap a radix/magnacharger on that bad boy .. granted .. your gas mileage will be absolutely atrocious but you'll get your acceleration back :-)

My last vehicle was a Ford Excursion V10, with a 6 inch lift and 38" tires. I averaged 7 MPG in the City, 4-5 MPG towing. My H2 feels like a tiny little sports car compared to that.

My H2 has a Magnacharger Supercharger (M90, not Radix), Cat Back Exhaust, and Airaid intake. I get around 11-12 mpg. I don't think there is a better solution, other that driving slower. And face it, that ain't gonna happen.

Has anyone tired removing the front driveshaft? I theoroize that removing it could reduce drag on the drivetrain and raise the MPGs. I think it could raise it up to around 16-17 mpg, but I have not tried it yet. (Nor do I know that it is even possible)

Good Luck

Calgary

don't do it, get an old Geo Metro.

For mileage tips, the big problems are weight and aerodynamics (plus full time 4wd, etc.). For aerodynamics, take off the crossbars on the top of the truck, which will reduce noise levels at highways speeds and buy you a boost in MPG. For weight, take it easy on the gas and put the weight to work for you by coasting to stops rather than hot-rodding up and slamming on the brakes.

Not to go off in a different direction, but does anyone know how I can get a better price on a new Bentley? Get my point?

Cold air intake, Cut out the cats and have it Dyno Tuned. My freind has a 04 Hummer he did this and gets 14.5 MPG now in city driving..I get 12/13 ish with just Cold air. The Dyno tuning turns off the error light from the Cats being gone, and it is tuned for performance/shifting, etc..

While I agree with you there to some extent CDI, you're going to have to put on A LOT of miles on that vehicle before you have paid for the mods by saving gas ... to me it doesn't seem worth it.
And 12/13 with CAI? I get that stock thank you very much :-)
