H1 figures are mine, filler neck to filler neck, speedo GPS verified
I have questions about h1 gas mileage just like phisher. You said an h1 can get about 12-13 mpg. I have heard around these numbers from most people. I have loved hummers ever since the age of 3-4. This year is my senior year and my parents have offered to buy me a used h1 (year 2000 and up) for graduation. My dad has talked to a few hummer owners and they had everything bad to say about them. We even test drove one of his customers 2002 h1 soft top. The experience was wonderful, but the vehicle had some problems during the two days we drove it. The first problem was the dome light kept on flashing and would take up to 15 minutes to stop flashing parked or in drive. The second problem was the rattles and sqeauks. Don't get me wrong I know a h1 will rattle and shake, but I mean these rattles sounded like the door was going to fall off. The third problem we had was the check engine light came on. We were not sure if it had to do with the hood latch to be somewhat up, because when we pushed it back into place the light went out...? It sounds like you have a lot of info on h1's or you may even own one. If you could give me a breakdown of the h1, the pros and cons, maybe even bust some negative myths such as 7 mpg...? That would be more helpful than you would ever know. I want to research this vehicle before I ask for a used one for graduation. I hope the h1 we test drove was just a fluke. I hope you get back to me soon and thank you...
It's very hard to diagnose specific noises, rattles and electrical problems over the internet. However, I can tell you that it's no more normal for an H1 to have bad rattles and shakes, a flashing dome light, or an illuminated CEL than it is for any other vehicle.
I'll hazard a guess that there's a bad electrical connection causing the dome light to flicker. The shaking is most likely caused by improperly balanced wheels. Mine is completely smooth at all speeds, but it wasn't until I took care of the balancing that it became that way. As for the CEL, you need to have it checked for codes, just like any other modern OBDII equipped car. You can have it done free at Autozone.
As for mpg (don't forget it's diesel), I'll get 12-13mpg driving briskly in town, easily keeping up with traffic but anticipating stop lights so that I keep rolling wherever possible, and maxing out at 65-70mph. However, I've recently been doing several thousand miles of 100 mile round trips, 1/3 town 2/3 highway. By driving as I normally do, but restricting my highway speed to 55mph I consistently get 14.5 mpg. As well as saving fuel, it's quieter at 55, and more relaxing too. Downside is slightly longer journey times.
An H1 is not the cheapest or most practical vehicle (unless you live in the wilderness), but it really is FUN!!! It's hard to justify for any other reason than you just want one, but that applies to many other vehicles from Corvettes to Jeeps.
If you have any specific questions I'll be happy to answer them if I can.
Kind of hard to answer without knowing what your current gas mileage actually is.
Any reason this is posted in 'H2 Wheels and Tires'?
A recent test of of our '06 H3 auto w/adventure pkg with 13k miles on the odometer, 10% ethanol, a maintenace dose of red line fuel additive, 42psi in the 33's, no noticable wind, a/c running, 500lbs total passengers and cargo, and cruise at 68mph yielded 19.5 mpg. Off of cruise and not keeping up with the front runners and yet not bringing up the rear lowered mpg by 2.
See post #6 for what I said about the H2.
Your 12mpg is pretty good. You might do a little better with a lighter right foot, and you'll do a lot worse towing or off-roading.

it's exemptions and tax breaks for cars like the Hummer that clearly show a lack of vision and undue poor influence in Washington. Of course no one in the current administration really cares about curbing our use of oil.

Actually, the exemption was provided because most vehicles above 3 tons are used for business purposes, such as contractors, farmers, etc.
Blame the customers for buying 3 ton vehicles - GM built them because the customers wanted them.
I have some Ford/Holden and probably lots of other auto related stock buried in those things but usually I just skim the major industries the funds hold. Tell your money guy he needs to diversify so he can lose his shorts worldwide like the rest of us have.
But ... we're really hear to talk about HUMMER MPG.
For the other issues, check out Buying American Cars What Does It Mean?.
You talkin' to me? Well, I confess I did own a 1989 Excel (for about a year), but my current ride is a Ford Escape Hybrid...
Back on topic, I'm wondering how many people actually use the excellent off-road capabilities of their H2?
OK, REALLY on topic, what MPG would it get off-road, or is it so bad on-road that it doesn't really make a difference.
How about MPQ (miles per quart). That might get you up into double digits! :P
SUVs and Smart Shopper
Looks like they are using an H3. See the video:
1) CNG is Compressed natural gas (the same stuff you heat your home with)... you can install a home fueling station, or (in our area) WeEnergies has a public pump with CNG now at .97cents per gallon!
2) In a Diesel Many people are doubling or tripling there fuel mileage 30-40mpg is very common on hybrid systems... use diesel or CNG (compared to 15-18mpg on diesel only)
3) torque is often 100-200ft lbs higher
4) CNG is more than 90% less polluting
5) Longer oil change intervals (engine runs cleaner)
6) Engines last longer (do to the absence of contamination).
7) Non EPA approved systems are about $3500 installed, EPA approved systems are $6000-$12000 (niether system is better, but BIG OIL is doing eveything they can to slow down the CNG revolution!...
Did you know the EPA is claiming they are restricting CNG installations in the name of "Public Safety?"... when in fact the EPA only has authority on air quality.. they have no authority over "public safety" only air quality "Does this REEK of BIG OIL?"
Also.. the EPA is charging manufacturers $250,000 to test thier equipment?... WTF?... (but no certification is required on the installer end?.... YIKES...Did you know the rest of world is moving very fast converting everything from Construction equipment, Transit buses, Trucks, Forklifts, etc!
Some say CNG tanks are dangerous. but lets look at the truth!... CNG is lighter than LP (propane), Deisel and gasolene, in the event of an accident CNG tanks have been tested in 100mph impacts without rupturing.. even if they did the gas escapes into the air... unlike LP or gasolene that puddles on the ground... and spreads an explosive flame!... what would you rather have?... a stamped tin or plastic Bomb under your car filled with gasolene?... or a tank than can withstand 100mph impacts?
WAKE UP AMERICA! the USA and Canada have a 250 year supply of Natural Gas.. that gives us an almost pollution free alternative... until Electrc Batteries are 75% cheaper, we can refuel them with solar, and battery life is at least 25years!.. Lets forget about Hydrogen... its doesn't make sense to take huge amounts of energy to convert Natural Gas to Hydrogen!... why would anyone want to take a fuel NG... spend tons of money to convert it to another fuel?... just use the base fuel to begin with (CNG).... Am I the only one that gets this????
However, I'm sure you know that while a CNG conversion to a gas engine is relatively simple, converting a diesel engine is a much more complex and expensive process.
Unlike a gas engine which actually benefit from an increase in compression if desired, a diesel must have its compression ratio reduced, which is usually done by changing the pistons.
Next, the gas injection has to be in a very non-linear fashion to meet the differing requirements as throttle opening and load changes, which will require an additional ECU. Fueling of the diesel injectors can be reduced though, but this will require reprogramming or replacement of the vehicle's ECU.
The CNG/diesel fuel mix doesn't ignite under compression so easily now, so an ignition system must be added and controlled.
Of course, this is a picture painted in broad brush strokes and there's a lot more in the details.
Perhaps the availability of CNG should also be considered. Probably all that need be said on that score is that major users of CNG in their vehicles usually take care of their own fueling needs and keep their fleet close to home.
So, for my H1 it certainly wouldn't be cost effective. I couldn't drive far enough or live long enough to recoup the cost of conversion, let alone save money.
It would be impractical, with every modification to the original being an additional potential point of failure.
Finally, it would be inconvenient to say the least, trying to track down CNG filling points in addition to conventional gas stations.
Now, in a world with CNG as readily available as gas or diesel is now, and in a vehicle designed from the ground up to use it as fuel, I think we'd find ourselves in much more agreement.
However, this argument for CNG has been made at since the 1970's to my knowledge, and probably before then too, but the adoption rate and availability of the product is little changed now to what it was then, and I really don't see it changing much in the near future either.
