Once more with feeling...
While agreeing with the above posters, there are many sources for independent evaluation of these and similar products. A couple of links:
1) The California Energy Commission. Note the subheading of "myths". While they haven't tested this particular one, they have tested several devices consisting of bar magnets mounted around a fuel line, and claiming to impact the molecular structure of the fuel.
http://www.consumerenergycenter.org/...ne_saving.html
2)The Environmental Protection Agency (EPA). Note that the EPA test results for the magnet devices listed above include the phrase "there is no basis for any claim to improved fuel economy or reduced emissions due to the installation of these types of devices"
http://www.epa.gov/otaq/consumer/reports.htm
My favourite part of the claim (these sites are always entertaining) is that the molecular bonds are broken, making the fuel particles clump together less. No, I am not making that up, the site uses the word 'clumps' to describe fuel molecules. Anyway, apparently this gives the fuel more volume (presumably sort of like hair spray does for hair). Breaking bonds, isn't that like fission? And even if you could break apart the 'clumps' of fuel molecules, an SAE fuel consumption test corrects for volume variation, bringing it back down to a mass measure of fuel (since that is what the energy content is related to). Wonder if the magnets make it heavier, too?
Great entertainment.
Cheers
Jeff
