A lot of it is really all in the way you drive. If I set the cruize at 62mph I will get 15 mpg in my H2 on the highway.
Take it EXTREMELY easy of stoplights (I.E. Let everyone fly ahead of you) and leave plenty of room in front of you at all times so you dont need to use the brake. I do this a lot in stop and go traffic, its amazing how many times people hit the brake in stop and go....if you just leave a little room you will probly hit the brake once for every 50 times everyone else does.
Do all of this for a day and check your milage. You will be amazed. Remember GO EXTREMELY easy off stops, and never push the gas more than 1/4 of the way.
Granted I hate driving like that, but it does save TONS of $ on fillups. Think of it this way...u cruize slow and the cute girls have more time to check you out =)
