I've had an H2 since 05' and love my truck. I am heading up a gold and silver exploration project and use my H2 in rough country everyday. I recently stumbled upon a rare mix of minerals that have interesting properties. I can set a bag of this crush volcanic pluton on my gas tank ( notice I didn't say in my gas tank) and the energy generated, micro clusters the gas molecules and makes the gas burn more efficiently. That translates into increased mpg (almost 2mpg) and decreased hydrocarbon emissions and lower nox emissions and slightly lower co emissions. Performance also increases about 18%. I have just completed a test on a new 2011 freightliner sprinter van with a diesel engine and increased the mpg 4 mpg. I have just started a website and you can see it at
www.structuredfuel28.com. Oil is also effected by this process. Take a look. Money back if you don't like it. This is advanced particle physics technology.
