Re: Gas Milage Tips And Mods?
I did a test with my Ford Expedition over the summer, don't think I mentioned it to you guys. Normally my expo gets about the same milage as mt H2.
Removed roof rack bars.
Clean, new air filter.
Overinflate tires 8psi over max recomended PSI.
Fold in mirrors on highway (The expedition has HUDGE mirrors).
Set cruize at 60mph.
Went from H2 range (11-13 highway) to 17.5-19 mpg highway.
When it comes to cars Im hooked on my Fiance's saab 9-5. Full size 4 door car. 4 cyl turbocharged gas motor. 3,500 towing capasity. 31 mpg driving it normally....agressivly when im driving it still gets 30. The thing its pretty quick once the turbo spools up. Problem is she gets mad when I drive it. lol.

Re: Gas Milage Tips And Mods?
Well all of you are smarter than me. I got 12.1 miles to the gallon for 6000 miles. Last October I purchased the Fuel Maxx Vortex Generator on Ebay for 12 or 15 bucks. I started noticing an increase immediately and showed everyone in the office the reading on my dash. It read 13.7. I have only seen it go down once and that was the trip to Jackson Hole, Wyoming last Xmas. It was as low as 11.8 in the high mountains but coming back gradually incresed to 13.9. I'm driving back to Elkhart, IN. tomorrow and see Stuart at OEMDASH. Got to install Black Rims and one more piece of carbon fiber for the sun roof controls. I will get 13.7 or better on the interstate guarantee. If I couldn't afford the gas, I wouldn't have bought a Hummer but 10 % helps for the hotel bill. I do remember my 1974 "454" corvette getting 5.5 mpg.

Re: Gas Milage Tips And Mods?
i have a bit over 12K miles on mine. Most of my driving is stop and start and i commute a whopping 3/4 of a mile to my office in it. The dash says 11.7 MPG. Last long trip we took if i recall right, we got a bit over 13 MPG i think. But we were driving between 75 and 85 on the interstates.
I think others have said this before....its a Hummer...its heavy...its shaped like a brick...it never was designed for gas mileage. If you can afford to buy the truck...you can afford to buy the fuel.
When we were at the Pittsburgh International Car show last weekend we were looking at the mileage estimates for the various vehicles. You would be surprised that a large number of vehicles only get around 15 MPG around town....not much bettter than the H2 and sure as hell nowhere near as cool as the H2.....well....all but the rolls royce they had there for $330K it only got 12 MPG around town....damn gorgeous car!

Re: Gas Milage Tips And Mods?
Really it depends on the area. Driving a H2 in somewhere like Long Island, NY is MUCH MUCH different from driving it in Colorado. In Long Island it never has a problem pulling 75-80 on the highway, in colorado its downshifting and fighting. In long island you get MUCH hight MPG than Colorado.
Altitude, mountains, hills, and winds (thats a big factor) really affect power and MPG.
My 05 F350 Diesel could only hit 75mph TOPED OUT (thats pedal to the floor) in Nebraska towing a 2 place enclosed snowmobile trailer....just because of the wind!

Re: Gas Milage Tips And Mods?
interesting reading of everyones take on mpg,..the first thing that comes to my mind on fuel consumption is axle ratio,..has anyone went to a higher axle ratio?..seems the 6.0 engine should propel the Hummer adequately with a 3.73 or a 3.54..comments?..

Personally I always keep the wind behind me --I find that a big plus and keep the air suspension raised in back so I"m also always going downhill. It's all good, Regards The Rebel. Sometimes the old timers have to show the kids how its done.
