Hummer Gas Mileage



  • steverstever Posts: 52,683
    I used to have some shares in a Japanese weighted ETF and they owned some car companies (forgot which ones - Honda and Toyota iirc). I still have some shares in an Asian weighted ETF and they own some Hyundai last I checked.

    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.

    "yes your absolutely right , it's good to be king. just remember what a wise man once said , dance with the one that brought you or drive yourself home. you have your options and i have mine. peace and may your hyundi bring you many minutes of happiness."

    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.

    Shouldn't it be not MPG but rather, GPM (gallons per mile) rating for these?

    actually does better per mile than some ford pickups and explorers. and as for off road it is a silly guestion. i don't care what someone's boat cost to run on the water. if you have an atv enjoy yourself. 16 t0 18 mpg is more than acceptable to me. what with all gas everybody else is saving under obama's plan there is plenty for me. :D

    but rather, GPM (gallons per mile)

    How about MPQ (miles per quart). That might get you up into double digits! :P

    PG&E is buying a couple of PHEV SUV's from these guys

    Looks like they are using an H3. See the video:

    CONGRADULATIONS!... H1 Hummers can go green!!... Converting your Fuel Guzzling Diesel H1 to CNG can triple your fuel mileage!

    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????

    Well, I certainly can't fault your enthusiasm. :)

    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. :(
  • has any one had problums with throttle response on there h2 ho to correct this problum
