I saw this deal in action last night on an 2002 F150 v6. My brother'n'law is getting about 30 mpg (it was 20 mpg) by using some sort of water/baking soda combo in a canister that creates hydrogen through electrolysis. Then he's got it being vacuum sucked into the combustion chamber through his PCV valve. He's got it wired to shut off w/ the vehicle and another bypass to shut it off at any point. Further, he purchased an O2 Sensor variable switch that allows him to tweak his air/fuel exchange. He's added another digital gauge...I think this is tied into his vehicles computer....that gives him real time feedback on all sorts of stuff...including MPG, avg speed, etc. Basically all the info we would get if we had a 08-09 vehicle with all the on board info.

I really thought this was a hoax, but what he's doing really makes sense....any mechanics or anyone out there want to weigh in?
