Is HHO technology a scam?

No, it%26#039;s not a scam- the process by which it works is a standard method of improving combustion in steam boilers.
The long-term implications of water-assisted atomization in gasoline engines aren%26#039;t good- there is a cost in terms of the service life of the engine... not to mention that it instantly voids your warranty.

If you do the economics, water injection is worth it, if you install it in a beater.

before you sift through all the answers of SCAM and it%26#039;s impossible, read about ultra-lean burning combustion engines. There%26#039;s a lot of untapped potential in gasoline. A lot of unburned gas goes into the catalytic converter, and only 20% of the normal air intake is oxygen.
I think every vehicle is different, and there are a lot of vehicles out there that have used this to increase mpg, some have not, maybe due to improper installation or not quite understanding how to get around the car%26#039;s computer fuel injection, and right now people are hearing from both.

no it is not a scam, i have used hho in my vehicle for over a year and it has helped. do not buy the water4gas type kits. just make your own genorator and you will be set. you should go to yotube and research hho.i i have done it, i know it works

Yes it is a scam... I am 77 and heard this all my life and have never saw one work yet.

first of all..its H-O-H lol and no its not a scam
