gas mph 05 vs 08

[HSTONKA]

I had an '05 SUT and recently purchased an '08. the difference is a little better. I transfered over the rims and tires so they exactly the same in that way.

'05 averaged about 12.5-13 mpg
'08 averaging about 14-14.5 mpg

That is better. I just put new tires on an 05 z71 suburban, (265's-265's) and no S i went from 14.5-16.2 MPG. (Computer said 15.9) but hand calculated 16.2. But an H2 getting 14 is nice. You shove it you Green bastards. My bumper sticker will say, H2...The Earth's worst Nightmare!

These Libs think THe H2 is solely responsible for the earth imploding. How about the millions of you smoking thos damn clove's or cigs, or other crap. That can't be good can it?

I have to agree that mileage should not be a consideration if you're buying an H2. I've gotten as low as 8 and as high as 13 mpg and averaged 11.3 mpg over five years and 76,000 miles of owning two H2s.

I am getting about 11.2 around town. Slightly better than my 06. I do have a heavier foot in the 08 since it sounds so damn nice when you get on it. My dad has an 08 also and lives in a rural area and gets upwards of 14 on his.

I will have to pull my manual but I could have sworn that it said hi octane was recommended. I run hi octane in my 08 since it simply runs alot better. Running regular it was sluggish and always hunting for gears. Hi test makes it run like a champ!

in my 2008 h2 sut i tried to run 87 and 89 and it hesistate under wot...but with 91 it pulls really strong...the hummer dealership told me to run 91 oct in it when i bought it and now i know why

I've run 87, 89, and 91 octane in my 08 and did notice perfomance differences with 87 but between 89 and 91 no big difference. Gas mileage had been right around 13 and up to 14 if doing a lot of 60mph driving out in rural areas.
