So I guess theres not much hope unless you leave it dead stock. Haha. Oh well!

Re: Gas mileage
 

I get 10.2, mixed driving. You can see my mods below...

Re: Gas mileage
 

I can understand your case..you have a ton more weight to carry with a lift and all the extra mods. I think performance parts may help mine a little but it doesn't really matter I guess. The gas mileage will suck regardless..haha

Re: Gas mileage
 

My stock 09 is getting 12.0 to 12.5 mostly in town driving.

Re: Gas mileage
 

Again, It's a Hummer H2, Your only going to get good MPG going down hill in the SOB!!!:giggling:

Re: Gas mileage
 

you know im at the track all the time racing my beast Andres. thats why i added the demonguard and gobi... for superior aerodynamics :giggling:

Oh and last time i filled my tank up it had about 220ish miled till empty... F*CK ME! :twak:

Re: Gas mileage
 

If ONLY hummers ran about 15 mpg across the board!! Hummers would be the absolute baddest rides on the planet if you weren't shelling out a million bucks at the pump! Stupid that the government relies so heavily on others for gas/oil, and then they jack the price up for all of it when we don't even really have a shortage.

:perfect10s: :giggling:

Re: Gas mileage
 

In the winter months I get anywhere from 10.8-11.2 in the summer 11.7-12.5 (I tend to tow more in the summer so it varies more). I have not really road tripped the 08 yet but I have driven on a couple of 200 mile round trips snowboarding this winter and Im not too impressed with the mileage on the highway (now I typically drive ~75mph) but it seems to not get any better than about 12-13...... Oh well, didnt buy it for economy:D

Re: Gas mileage
 

Stock size wheels and tires, no other engine/exhaust mods.

All city driving is high 8s.. and I've used the fill up, drive, fill back up formula several times.

Get on the highway and I'm about 12. I drive 65-75 MPH...

Re: Gas mileage
 

Woo..not gonna lie that's rough.

Re: Gas mileage
 

Couldn't tell you because I don't care. I don't own 3 Hummers because I care about gas mileage. Instead I would a Prius, Focus, or some other stupid little 4 wheel piece of crap.:clapping:

Re: Gas mileage
 

Haha..I hear you!

Re: Gas mileage
 

Ya seems low to me as well. However when I look back on all of the new cars that I've had, and used, I'm always below the average gas mileage.

I think it's just the way I drive.

sweet spot rpm for better freeway mpg
 

I have to commute 2x a week with my h2 about 100 miles each way, 400 total miles per week- all freeway miles. I have 37 inch tires , (inflated to 50 psi )with 4:56 gears, I try to drive at about 2k rpm (equals to 63 mph) which seems to give me better mpg on the computer (not sure if this is BS or not).

What other minor tweaks can can I do to improve the mpg on the freeway? Or should I juss say **** it and enjoy the commute? Im not sure if babying it even helps on the freeway.

Re: sweet spot rpm for better freeway mpg
 

What are you getting right now?

Re: sweet spot rpm for better freeway mpg
 

It is all over the place, depends on how I drive, elevation, where I am going, etc. My computer says now 11.4 mpg avg. I am going to baby it on this weekly commute I have and check the results manually.

Re: sweet spot rpm for better freeway mpg
 

11.4 is still a good bit better than the 10.2 I get with my 35's..I'd take that in a heartbeat! Do you think something like a wester's hot tune, or something of that nature would help?
