2003 H2 over 50K miles and when I traded it in my average was 10.6 mpg. I could hit 15-16 average mpg on the highway driving very carefully. I don't think the H2, at least the early ones, are going to do much better than that. i knew a number of guys that did the exhaust, air filter, pcm mod and didn't get anything but more grins per mile.

I spend over 10grand a month in gas with our limo fleet, most of it coming from the h2 limos. Few things you can do:

reduce weight, every little bit counts, easy stuff is remove the spare tire, if its inside you get more interior room and then you can install a 2-3 person 3rd row seat, if its outside it gives you a cleaner look. This is a big weight savings especially if you have the outside tire with the rack. Remove cross bars up top, saves weight and drag.

We run airaid air filters on all h2s, this should help bump gas a little. Plus they pay for themselves as you dont have to buy new air filters all the time.

Keep tires properly inflated.

Ok, So i eneded up getting the SuperChips FlashPac tuner. It improved my shift pattern and shift firmness to my liking. Fuel Mialeage has increased by 2 MPG on the first two tanks of fuel! This reads all trouble codes and can clear them as well. Overall performance has increased as well. CAI and exhaust are next to reap the benefits of the tuner.

So far so good. Sounds like a good mod. What do you have invested in the 2mpg increase?
