Better milage-HHo gas = SCAM?

[Snowman66]

Do these things realy work. Can anybody verify? I think HHO is a scam becouse if we all could get 25% better milage it would save us $billions. A product that would save us $billions, there would be so much $ in building HHO generators that it would attrack far more than E-bay garage production.

Just think of heavy equipment engine builders, if they could make there engines burn 25% less HHO generators would be standard equipment.

What do uou guys think?

I have made some of those generators and the ones I made do work. I put one on my 2000 caravan and got almost 25% from the git go
I also put one on my ford 93 van v-6 3.0 and that got me about 20 % and have been running one for about 8 months.
My friend has 6 on his dsl boat engine cummins, and says he has in the 15-18 % range. I am getting ready to do another one for my boat as well.
I did a lot of checking before starting out and found that they work better on older vehicles and ones w/o so many sensors on um. Like the e/g/sensor. It takes the eng. about 4 days to figure out that the exhaust is a little cooler and trys to add more fuel. this is easly over ridden, but that is what goes on with the newer cars or trucks.
The diesel w/o computer inj pumps work better than the newer ones w/the comp. injector.
I also have been running mixed cooking oil in the boat for over a year and 3500 hrs. No problems at all. It is a big savings when fuel is 5.15 at the marina. It is down now to 3.10 or so now.
Both of my F-350 p/u run on mixed oil too.
