Do you know how does HHO Booster work? It’s very simple really. You don’t touch your engine. A small container is placed in the car, somewhere under the hood. You fill it with water. The device is supplied with electricity (12 Volts) from the battery, and via electrolysis it produces HHO gas (Hydrogen+Oxygen, Oxyhydrogen)

HHO booster helps your gasoline burn more efficiently and increases your vehicle’s gas mileage between 25% and 50%. Now, consider for a moment that your vehicle has a 20 gallon gas tank and averages around 25 miles per gallon.
 
The HHO gas is supplied to the engine via intake manifold or carb.

It’s very simple. You don’t change your engine or ECU (car computer). A quart-size (95O cc) container, usually made of glass but can also be plastic or metal, is placed somewhere under the hood. You fill it with distilled water and low-cost household electrolyte (causes electrical current). The device gets vacuum and 12 Volts from the engine, and produces HHO gas (Hydrogen+Oxygen) as shown in the video

Do you think trillion dollar oil companies want you to find out the truth? Of course not. It would cost them billions. That’s why they programmed society through advertising and media so that anytime somebody talks about cutting your fuel costs by 60% your mind is immediately thinking "that’s impossible" or "it doesn’t work".

The big secret is that water (H2O) can be turned into a powerful fuel (with a very similar formula, HHO) through an easy process called electrolysis. This resulting gas - HHO gas- is rich in hydrogen that your engine can use as a clean water fuel.
