Amazing

I easily got 15 while stock. It's not uncommon.

I call BS---I've got a lead foot and can't claim mileage. But my wife drives like an old lady and has only ever pulled 12 on a tank after multiple tries. I can't see it getting 3mpg better than that "easily".

MAYBE an 08/09 truck, with stock tires, and a very light foot on the pedal.

Stock my 04 was right in the 12.5 or so range, on a mostly highway trip I could get around 14.5 +/- assuming there was no wind.

With 37's and a Hypertech Max Energy I'm at 10.8, that's about 30% highway, 70% city. Without the tuner, and on 37's I was in the high 8.something low 9 range. Although, within the last couple of months I've turned off the DIC all together and just drive the thing, there's no point in obsessing about it.

There was a time, a couple of smart phones ago, that I had a photo of something like 26 mpg (instant) at 75 mph! ... of course that was in about a 30 MPH tail wind and down hill!

I have 106,000 miles on my H2 and haven't reset the mpg lie-o-meter since the day I brought it home new from the dealer. It currently reads 11.0 mpg. I got a 0.2 mpg boost around 50,000 miles switching to Mobil 1 synthetic. I do a lot of highway, towing. winter snow and mudding at construction sites.

I'm getting 10.5 with a 6 inch lift and 37's and am very pleased with that.

I'm gettin' 11.5 with a Cognito UCA leveling kit, 1" rear spacers and 37's; when stock I was at 12.5.

What's the big deal guys? A taxi will charge you $15-$20 just to take you 10 miles.So what if my HUMMER will only get 10-12 miles per gallon, I just spent $3.90 on a gallon that will take me 10-12 miles. I just saved $16.10, I think I'll spend it on pizza tonight.There was a month that I had to rely on public transportation( Taxi/train/bus ), it cost me $800 and I definitely missed the comfort of my HUMMER.I spend about $350 a month on gas.

I know for a fact that you can get at 15 MPG in a HUMMER H2 as long as you:
1. Are the only person in the Vehicle
2. Have less that 1/2 tank of fuel
3. Drive to and from work downhill
4. Fold in your mirrors
5. Be in a vacuum
6. and last but not least: Install the Tornado

What say all the neigh sayers now?
