Legit product or snake oil?, Yet another "Fuel Economy Booster" Options

[senick]

Check this out, I happened across this little product:
Here

Seems a bit suspicious, "When plugged into the cigarette power port of a vehicle, the Fuel Doctor FD-47 Fuel Efficiency Booster helps to clean and condition the electricity in the system"

Not sure how that would work...cleaning electricity? I'd give it a whirl just for the hell of it, but then I'd just feel like a chump when it inevitably amounts to a placebo at best.

here are several tested results for products of the fuel saving nature. That exact product is on there, and is one of the few that showed any improvement (a few actually showed a decrease in mpg).

LMFAO, the bottom one on this link claims that fuel molecules cluster in your tank over time and the molecules in the middle of the cluster cannot be exposed to oxygen for proper combustion. First off, the molecules do not "cluster" as stated. Secondly, if they did, the only way the ones in the middle wouldnt be exposed to oxgen would be if the fuel was being ignited inside of the tank. Not to mention the fact that fuel lines, pumps, and just adding fuel to the tank mixes everything well.
