Gas Mileage

Lately I have been getting crap from people about having a HUMMER (like they pay my gas bill), but I get 13.4 MPG, at least thats what the readout says. Do you think the readout is correct, I have never figured it out manually. 

When I figure it out per tank it is significantly higher that the average shown on my guages...

My 2003 H2 average much less than that by the computer ( 10.8 I think ) Don't remeber ever calculating it manually.

i guess it would depend on what kind of hummer you're talking about. 13.4 is pretty good for an H2, not so good for an H3, and might be good for an H1 - don't know what they should be.

I would be very happy with 13+ on the H1s.

I show 13.4 on my readout out as well and have not reset it since I got the truck. So from my perspective thats a pretty good average, so I never really cared about checking it.

mine says 10.5, and it is pretty much right on the money

i don't look at mine anymore.  after looking at the instant mileage while i was pulling the camper, uphill, i got too depressed.  now i ignore it - maybe it will go away . . . .
 
i do know i'll never, ever, rely on the "range" reading again.  especially not when the next exit is 10 miles away in the middle of Nevada . . . . .

Mine 10.3 according to my readout for in town driving, haven't saved up enough for a long trip yet.

Lots of threads about this already, elsewhere!
 
10-15mpg on a US Gallon. More on a Canadian gallon, since gallons and dollars are bigger there now.
 
Depends if you drive in city or highway, or both. Also depends on if you have a lead foot, altitude, and millions of other variables.
 
13.4 is great overall on an H2, even a new one.
 
 

Good to know. So when I see the yellow light come on I had better be looking for a Gas station quick? Needles on E but it is still saying I have 29 miles!

Most manufacturers build in a generous reserve (about 20 miles) before you actually run out. This is common, and can be very helpful for those people who like to run the tank down all the way.
 
On some models (other makes), the gauge will read below empty.

I finally filled it up and figured out that I am getting around 13.3 MPG on mine. I haven't pushed the orange light on it too much though. Thankfully I am only 2 miles from a Chevron or Safeway and about 10 from a Costco. I have a 350Z that the orange light comes on at around 30+ miles and I have pushed that thing to the point of fumes but the H2 I'm too nervous about it breaking down on the side of the road. Plus, I heard that you never want to run on empty too often because of the sediments settling at the bottom of the tank? Is this true or something my Dad is just pulling my chain so he never has to come get me when I run out?

Your dads Right, hes just not Pulling your chain..........
 
When you run your tank down to the lowest, the fuel at the bottom of the tank has partacals of dirt,rust, water and seditives in the Remaining fuel..........when you run it dry, it sucks up that fuel and gets plugged in you Fuel Filter...........
 
When you Re-fill your tank, from running it dry.......you could have some Running Issues later...........
 
But it also depends where you get your Fuel at also.......most new Stations have filters at the Pump before the Consumer gets the Fuel.........
 
I have a 1/4 tank rule...if it gets to 1/4 tank I get it refuled............no matter what.........
 
Im always Glancing at the fuel, just in case Im on I-95 and theres a Wreck and I have to sit there for a Couple of hours..........crawling along.........down the road.....
 
 
 
 

My truck just rolled over 75000 miles (2005 H2) and my gas gauge says it's getting 14.7. When I first got the truck, I calculated  it and it was right on. So I assume it's been "on" since.  I do drive the speed limit and don't -at least I try not to- "gun it" from a stop. As far as what other people have to say about you driving a Hummer... Who cares?

My 2005 H2 is at 65,000Kms and the mileage is rotten, about 8.7mpg or 23.3litres/100k, not great! I drive it normally but love to ram it through snow whenever possible!! :-) I also make sure I have at least a half tank when I am going out anywhere, just in case!

Anyways when people say " Good on Gas?" as they see me at the pump, I just flip them the bird and go about my busniess, unless they want to pay the should shut it!

My H2 gas mileage is really sensitive to tire pressure.  I had a tire start to go down very slowly.  The gas mileage started to drop almost as quick as the tire pressure.  Once tire was fixed gas mileage came right back up.

So, Where is the Dead Horse? lol
