http://www.supergassaver.com/ : As fuel sits in the fuel tank, changes in temperature and humidity cause it to expand and contract. Eventually, the hydrocarbon molecules in the fuel begin to attract each other, forming molecular clusters. Placing the Super Gas Saver, on the Supply fuel line, causes the re-alignment of the charged particles surrounding the atoms that make up the hydrocarbon molecules. This forces the molecular clusters to break up and expand. More Oxygen will now combine with more of these hydrocarbon molecules, which are no longer in clusters, for better, more efficient combustion in the firing chamber. Since Fuel is now burning more Efficiently, the result is reduced emissions, less fuel needed to reach and maintain speed levels. Carbon and Varnish build-up is eliminated, thus reducing maintenance and prolonging engine life. A "cleaner and hotter" fuel burn also increases Horsepower and overall engine Performance
OOOooo, "...re-alignment of the charged particles surrounding the atoms that make up the hydrocarbon molecules." Let's see, those charged particles must be electrons. So this device ra-aligns electrons. I wonder if it can comb your aura too?
My own electrons need serious realignment. Some of them are 64 years old. Gotta stop those damned molecules from clustering up in the first place. These scams make Popeil look like Henry Ford.
It looks like a magnet that sits on the fuel line. Complete baloney - even though one would think that it must be true because it's advertised on the internet...
