Cut and pasted this from that message board I posted a link to before. Truck hes' talking about is a 75 chev with a 350, used to get about 9 mpg.
Impressive results for a hoax involving a gas that doesn't exist.
(Still don't have mine in the truck, I have succeeded in getting my garage to look like a meth lab tho...

)
"well I finished installing my 3 cell system on my truck today and performed my driving test for MPG after draining the tank and running the carb completely dry I put 1 gallon of gas in the tank. With all systems a go I headed for the Walt Witman bridge which is exactly 30 miles from home. I went to and back and then to a friends house which is 2 miles from my house I ran out of gas in his driveway.
The speedo read before I left 97.900 and after in my friends driveway read 97.962 so the truck went 62 miles on one gallon of gas , I am truely amazed ! I really believe my way of getting the hydroxy into the cylinders makes all the difference in the world , I have each runner on my intake ported to accept a 1/4 inch barbed brass pipe nipples and I run hydroxy to each runner . This truck only got 9 miles to a gallon before I put the hydrogen booster on my truck.
Fact is theres a lot of room for improvements and I can tweek this and even get more and as time goes on and I will . Tomorrow more testing will be done to see if I get the same results . This time I will drive to Atlantic city which is the same approx distance See I live in south Jersey 30 miles from Phila and 30 miles from Atlantic City. This is a 3 cell system and each cell draws about 2.5 amps I figure if I add 1 more cell I should be able to bring the amps down to under 1.5 . The temperature stays around 100 degrees no matter how long they run. The KOH really helps .
I got to believe though the hose routing going to each runner on the manifold really makes this work the way it does. Its on to more testing and I will post my results as I get them. But 62 MPG dam I won't sleep tonight thinking about it. Hydrotech"
