Bottled water averages about $1 for a small bottle and that equates to about $8 per gallon. Go figure...

I've been getting 37 mpg by running on bottled water. Then my H2 learned that Aquafina was really tap water and now it won't run at all (go figure ).

Seriously, this is an issue I have discussed at length many times with Mike Sabarrese (Cerritos Hummer Service Manager and H1 Racer for Hummer). He keeps returning to the notion that the engineers at Hummer or GM already designed and tuned your beast to get the best posssible mileage you can. You can spend a fortune on upgrades which claim improvement, but the only 3 things that will really help are driving like a little old lady or converting to the Duramax Diesel engine (ca. $40,000) or leaving her parked. So enjoy your Hummer, just the way she is.
