Hummer H2 - How Can I Get Better MPG & Reduce Emissions?

Hi!

I Have a Hummer H2. I know, the most unfriendly vehicle as far as gas milage is concerned.

I would like to know what suggestions any of you may have so I can improve my gas milage (Besides selling the car or destroying it).

I read the Goverment newsletter on how to improve gas milage and it is very basic. Drive at 55mph, do not make hard stops, use gasoline that is the cheapest, etc...

I have heard of gas improvement gadgets like the Vortex Valve, the Tornado, Fuel Saver, Fuel Optimiser, and other gadgets that either work with the intake valve or magnetically on the fuel line.

Do any of you know if these work and if not, is there somenthing out there that will improve gas milage and reduce emissions?

Thanks!

Most of those are definitely scammish. Is your H2 M/T or auto? I'm assuming you have the 6L V8... Assuming this isn't a troll, you're probably going to have to go after aggressive gearing/rolling resistance/aerodynamic mods to reach the 20mpg range, but I'm sure you can approach 13-15mpg by limiting the amount of city driving you do and only going ~55-60mph with the cruise control on during highway stints.

I agree with SVOboy. Most of the gadgets are just gadgets...

think of it like this.

You paid what, $30k for your H2? If it only cost the Hummer people an extra $50 for some magnets, a tornado, or a fuel vaporizor to turn your 10MPG vehicle into a 20MPG vehicle, why wouldn't they install it themselves?

Imagine the advertising potential for a 20MPG Hummer.

That alone should make anyone realize that the gadgets, while interesting (That you should investigate---I'm sure they're advertised on this site), probably won't work.

Unfortunately, no scientific or intelligent rationale. Just bought it because they gave me a great deal and my wife and kid loved the car not to mention myself.

This is one of those things you then have buyers remorse...

My current mpg is 10 - 13 depending on either city or highway.
