Well not just water! That's how people get confused.....
We're talking gasoline as usual and HH0 gas given off from water (electricity from the car's battery is passed through the water to separate the Hydrogen and Oxygen) via an easy to install kit sitting next too your engine so that your engine works better (combustion improves) hence mileage improves ( up to 50% recorded).
The hybrid conversion kit can be fitted by any home mechanic no problem and necessary parts cost less than $100 and are easily found at any decent hardware store or DIY emporium.
So not only is you weekly fuel bill greatly reduced but added benefits include your engine ibeing cleaner, emissions seriously reduced so less pollution AND you might be eligible for a cash payment from the government for using the latest green technology as you are now driving a hybrid car.
