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 =)

I've tried John's suggestions and they work. Here's a few more:

The H2 is heavy. When you are going down a hill or slight grade, take your foot off the gas. You'll be surprised how well the truck maintains its speed.

Correct tire pressure is 37 PSI. Most gas stations, etc., will inflate the tires to 32 or 33 without thinking. Make sure they are inflated to 37 psi when they are cold.

Use the cruise control whenever possible and safe. Especially on a freeway, it gets good milage.

All of this gets natural after a while and you don't notice it.

Best regards,

George SSSS

I have a H-2 2005 LUX with 2400 miles so far, city driving, and after this 1st oil change I went with Mobil-1 and went from 9.9 to 10.1 on the dash meter for fuel consumtion, so this might help.?
I dont know how reliable the dash meter is but it seemed to help?
anyone else done this and did it make a difference?. I havent done anything else to the truck.
