Re: gas mph 05 vs 08
I have a 2007 & 2008 H2.......and to be honest, I am not impressed with the 08's fuel economy at all. I could be wrong, but I dont think something is right on my engine on the 08, it seems so WEAK to have 393hp. I can take the 07 and go up hills without downshifting, and the 08 has to downshift on pretty much every hill when it has more horse and more torque. When I first got my 08, I did hit 19 mpg with it one time, but now, I cant seem to get it over 14mpg. I am gonna take it to the dealer and let them check it out. I really dont see any differences between the 6.0 and 6.2 in fuel economy cause with my 6.0 I have gotten as much as 18mpg with it.
Most will say its impossible, but as long as you keep it around 55---57mph on the interstate with the cruise on, it will do it.
