Anyone have any ood Tips or Mods?
I Have a 03 h2, I am Averaging about 11.6, which is not bad. Is there anything that anyone has done that actually increases that number? Again, I Knwew what i was getting into, ( I also have a V8 Cj5 and a Lexus Lx 470).
Would a Supercharger help? Which Chip is the best? What about Cold air Intake?

Ive also got an 03 and its on 38's. I put a volant intake system on it and it increased a whoppin 1mpg. The performance programmer is on the way and its supposed to help a little too so Ill let you know how that works on my truck when im done installing it. My total right now is 9.9 so youre doin a little better than me!

i have a corsa exaust and a magnuson super charger and i went from 10.7 to 9.4 mpg avg. i think it droped cuzz i step into it a lil more now not crazy but a lil bit.

Thanks Guys,
So Which Mod If Any has anyone added that helped? The Hypertech Programmer Claims Better Fuel economy. anyone try that?


Has anyone done anything that actually raised the average?

i think your gonna hard pressed to find anything that will "noticeably" increase mpg , but if u do, let us know, i have the hypertech programmed for 37x13.50 tires and i havent had any luck with gas mileage from i think using criuse control might help on the highway thou

Thanks Matt,
I Was Just trying to figure out if there was anything worth trying.
I LOVE the Vehicle, I Bought it to use as a Rolling Billboard for my florida Condo Rentals Business. I Am an Avid Offroader as well.

Anyone try E85? Is the Hummer E85 compatible?

A lot of it is really all in the way you drive. If I set the cruize at 62mph I will get 15 mpg in my H2 on the highway.

Take it EXTREMELY easy of stoplights (I.E. Let everyone fly ahead of you) and leave plenty of room in front of you at all times so you dont need to use the brake. I do this a lot in stop and go traffic, its amazing how many times people hit the brake in stop and go....if you just leave a little room you will probly hit the brake once for every 50 times everyone else does.

Do all of this for a day and check your milage. You will be amazed. Remember GO EXTREMELY easy off stops, and never push the gas more than 1/4 of the way.

Granted I hate driving like that, but it does save TONS of $ on fillups. Think of it this way...u cruize slow and the cute girls have more time to check you out =)

Frankly, if you're worrying about the fuel consumption, then you should have bought something else.

yeah , seriously hummer was not meant to have good gas mileage if i was worried i would have got a hybird or whatever the fukk they are called but the above ideas will save a little like the cruise control idea

Now, See, i New I would get that!

The First Thing I Said Was, I Knew What I Was Getting into. The Hummer is actually the best vehicle I own on Gas Mileage ( The LX470 Actually gets about 2 miles bettwr But Requires Super. The Jeep ( CJ5 with a 360 V8 Gets about 8 because of the gearing and 35's).

Here is what I did....

I previously owned an 8.1 litre Chevy 2500HD. The gas milage was so bad, I bought an H2 and now I get better mileage.

Moral of the story, buy something else if you are worried about gas mileage

Frankly, the guy doesnt give a **** about fuel mileage. Did you see his list of rides? But it doesnt hurt to ask for help about more mileage anymore than some of you donks that need help with more lift or more power.

x2 what tomp said. I had the 2500 Avalanche and am getting much better mileage with the H2. On the other hand, I'm also getting older and racing from traffic light to traffic light has lost much of the appeal it once had so I've been doing what Johndjmix1 has been doing. My overall average gas consumption since buying the truck almost 3 years ago is 12.3 mpg city/highway and miraculously I'm still making it from here to there.

Something to consider:

Bottled water cost more than gas and which do you think is easier to obtain?

Bottled water averages about $1 for a small bottle and that equates to about $8 per gallon. Go figure...

haha thats funny coca cola sells water for more than coke and the water is the same they put in coke.

Im hooked on that FIJI water its like $2 for a bottle at 7/11.

O.K., Thanks Dug..
I Know where these guys are coming from, Thats Cool.

Now , Im Not Sure how we got to coca cola. Let me Refraise the question:

Did anyone Notice a Fuel economy Differance with the following Upgrades-
( As I Said, I am Already Getting 11.6 ( Pretty Happy With That).

Cold Air Kit -
SuperCharger-
Cat Back system-
Programmer/Chip?

I Am Considering these and the hummer dealer ( Whom I Do not Trust, Since they where closed down a few months back because the owner got caught dealing cocaine), Is claiming better performance ( Duh! ) and BETTER FUEL economy.

I Don't Mind Dropping the cash, I Just don't want to End up getting 7 miles per gallon because, we drive this vehicle all over the country.

If Someone could give me an honest opinion without desending into the realm of bottled water and coke, that would be great..

Lext: One of the things you will find out very quickly in this forum is that discussions morph very quickly from their original topic. It's something you will need to get used to if you want to keep your sanity . To your immediate question indirectly, I have not spent any money on the mods you mention because after reading the archives of this forum I was not able to find anyone who could conclusively quantify any gain in fuel economy. I thought about purchasing a catback exhaust system which purportedly improves fuel economy but I wanted it more for the noise. I finally decided I like the quiet rumble the vehicle already makes and left it alone. Don't know if that helps any but there it is... no morphs either .
