Fitch Fuel Catalyst

Is anybody familiar with the Fitch Fuel Catalyst?  I know someone who recently started dealing them, I know someone who has one and swears it really does work, and I've seen testimonials ranging from the fire department in Denton, Texas, to Esso Europe, to the US EPA.  Yet, like everybody else, I'm suspicious as hell. Can this little device, dropped into the tank of your car or furnace or lawn mower or scooter or oil furnace, really keep the fuel fresh, reduce emissions, and cause the fuel to burn more efficiently, thus... saving you money on your oil and gas bills?

My dealer friend spoke to someone who had a Fitch in an old car, which he sold to his daughter.  He'd kept gas cost records on the car before, and when the Fitch was removed, it cost an extra $50 CAD for his daughter to drive the car home.  (She lived within driving distance, which was about 1400km.)  A journalist I know has one, says it does improve his fuel efficiency "significantly" and that his Jeep runs more smoothly since it was installed, and he's about to go buy another one for his other vehicle.  I've also seen some chem guys swear it's impossible and must be a hoax, but invariably they haven't actually tried it.  If you've tried the Fitch, please drop me a line. I would love to hear more from people who have actually used it. (But if you haven't, kindly stow yr speculations. After all, scientists have proved the bumblebee can't fly.)
