HHO stands for Hybrid Hydrogen Oxygen and is a technology that is an alternative to “gasoline only” car engines.

Specifically designed to mix with conventional gas, HHO make gasoline burn cleaner and with more combustion.

Therefore there are many benefits. One is that the engine runs quieter. Depending on the car you use there could be a considerable gas savings too.

Many claim they are getting up to 50% better gas mileage after installing the HHO system to there car.
Now with gas getting expensive you can imagine the number of gas saving devices coming out of the wood work. some work and some do not.
