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'?

We've moved the post over to the generic Hummer mpg discussion.

Magic would be increasing the mileage to 35 mpg.
