What is your real world fuel economy? Wondering if those extra gears do anything. Strictly curious for a comparison to my lifted T.

Guys this is in the h2 section not the h3 section. The 2008 h2 has the 6.2 L and a six speed 6L80E vs the 6.0L four speed 4l65E found in previous models

You are correct, this is the H2 section (and I purposefully posted this here). I meant to ask what I asked. :)

I think RHill is the only '08 H2 driver on the forum.


I have an 08. Before I got an OEM Hummer roof rack the truck would get 14.5 mpg on flat ground. With the roof rack I get 12.5mpg. This is at highway 70mph speed. City mpg is 12.
