Gas Milage Tips And Mods?

[Lext]

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?

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

[boo4u]

Magnacharger, Extreme Flow CatBack exhaust = 10 mpg. Supercharger is worth every penny and future ones as well with the fun factor!

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!

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.

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

THANKS GUYS!
Thats Awesome Feedback.

Hey I Notice a Lot of You are in South Florida. I Live in N.C. now but grew up in Fort Laud. (Coral Ridge).

I Used to Take an Old IH Scout out to what is now the area around Broward mall and Four wheel all the time when i was in High School ( At Nova, in the late 70's).

That Stuff is all Gone now though I Bet!

I Love this vehicle. I have only had it 2 weeks but I can't wipe the smile off my Face!

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

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 .

I also have tried the intakes and exhaust only to return most of it back to stock with the exception of the airaid air filter, and a programmer. (11.6 mpg) Also think about how long it would take to make up the 700 to 1000 dollars in cost if they did work. You might save five bucks a tank. 100 to 200 tanks later you might break even. If you want a small performance gain do it. If you want the gas savings, not worth it at all. The only big performance gain = supercharger IMO

My Volant intake increased my MPGs by a whoppin 1.5 mpg! lol. but hey, if you add those 1.5's up, thats quite a few more miles you can rock the truck down the street!

Was that 1.5 mpg averaged over a few tanks, so as to make a pretty solid estimate?

[NEOCON1]

up your highway pressures 5 psi , this is the best way to increase your mileage , next to pushing it

Enjoy your H2... they are AWESOME, and get used to being flipped off by granola eating, tofu farting ferries!!

Thats So Funny, It Happened to me today ( Other car was a Dodge Neon! ), Thats Gotta be fun to drive..

[Lext]

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?

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...

I've been getting 37 mpg by running on bottled water. Then my H2 learned that Aquafina was really tap water and now it won't run at all (go figure ).

Seriously, this is an issue I have discussed at length many times with Mike Sabarrese (Cerritos Hummer Service Manager and H1 Racer for Hummer). He keeps returning to the notion that the engineers at Hummer or GM already designed and tuned your beast to get the best posssible mileage you can. You can spend a fortune on upgrades which claim improvement, but the only 3 things that will really help are driving like a little old lady or converting to the Duramax Diesel engine (ca. $40,000) or leaving her parked. So enjoy your Hummer, just the way she is.
