Default better gas mileage?

hey everyone, is there anyway to make the hummer (h2) get between 15 to 20 miles per gallon without doing the diesel conversion? my dad really wants to get one for me and him to share he just wishes it wouldnt get such bad gas mileage. please dont say " you dont buy a hummer for gas mileage..." i know that but i really want one but he wont get one unless it can get a little better gas mileage. so are theres any little tweaks or parts you can do or get. thanks guys

Ok, here is idea...

Remove all the seats, take off the spare, side steps, remove any excess body armor. Change the tires to low profile or hwy tires, change out the rims...and the maybe you'll gain one or two points in mpg...

Other then that, not sure...

Fill up gas tank at top of a really long hill and coast down as many times as you can while driving very conservativily back up hill, repeat till average
on DIC reads out 20 or more mpg.

Car Max claims a 2008 H2 will get 17mpg on the highway - must be that 6 speed transmission, my 04 won't get more than 13/14

Just buy an 08 or 09 and do a lot of highway driving. On a trip from Denver to St.Louis last month I averaged 15.6 mpg according to the meter running 70 mph on hwy 70. I was by myself and running with a 40 mph tail wind across Kansas.

When I saw the question, I knew what was coming!

Get a copy of photoshop, doctor the manual, and show it to your dad.
