There was a post on here a few weeks ago about how if you drive 55mph you can get a 42% increase in fuel economy and that is DEF. TRUE!
Everytime I get on the interstate I put my cruise control on @ 55mph, and when I am going down the side roads (country roads) I run around 43mph so that its in overdrive and only churning about 1,100---1,200rpms.
Before I got my 07 H2, I had a 07 Escalade ESV as a demo with the new 6.2 Liter V8, and I was able to get 24 miles per gallon with it
filling up at a Shell Station, getting on the interstate and putting my cruise control on at 55mph and running a 60 mile stretch, and returning to the same shell station to top off with fuel to get a accurate reading.
So my prediction on the 08 Hummer H2 with the 6.2 will be 22---24mpg ((if you drive 55---60mph with the cruise control on))

Huh... The 6.2 in my 2500 chevy has not seen 13 yet, in 5300 miles......
