I can tell you from reading thier page that it is complete bull S$%T.  To
start, why would something that cuts 20% of gas usage not be standard
equipment on cars?  Some say the big oil conspiracy, but the car companies
still have to meet the EPA fleet mileage requirements and this would be an
easy way to do it.  Secondly and more importantly they claim that thier
device is "Powered by Neodymium Superconductors."  Funny I hadn't heard
anything about someone developing room temprature superconductors, let
alone 200 degree F superconductors.  The Neodymium they refer to is just a
type of strong magnet.  All these things are are magnets in a nice little
plastic case.  If exposing fuel to a magnetic field did so much, why didn't
the same thing happen when the fuel went through the fuel pump?  It has a
nice strong magnetic field.   It is amazing that companies like this aren't
shut down for fraud.
