A couple of years ago I was at a family reunion at a nice little campground set back in the mountains. As my late uncle Stanley drove up, I noticed a rather elated smirk on his face. When he got out of the car, he announced “I just drove the 112 miles here on two and a half gallons of gas!” This caught my attention, because he drove a late 80’s model Lincoln, a car not known for its fuel economy. To take an older car that got around 18 MPG and turn it into a 44 MPG powerful luxury car, is impressive to say the least. He then elaborated to me that what he had done was build what is called a Hydrogen On Demand system for his car from household objects and parts you could get from the local hardware store. After he showed me how seemingly easy and simple it was, I had to go home and get online to do a little more research for myself. I got online and ordered one of the numerous guides available to give you the ins and outs of building this green, money saving modification.
For those of you who don’t know what a Hydrogen On Demand system is, let me elaborate. A Hydrogen On Demand system creates a hydrogen/oxygen mixture that you inject into your air intake to increase fuel economy and even horsepower. Not only does the hydrogen act as a fuel additive, but also helps in the complete atomization of the gasoline to create a full burn of the fuel to create a cleaner, less harmful exhaust. The reason its called a Hydrogen “On Demand” system is because you’re not storing the oxyhydrogen, or HHO, in a tank. This makes it a lot safer because hydrogen can be a pretty volatile fuel like gasoline. The benefits of the “on demand” system is it makes its own hydrogen through electrolysis of water with a little help of a catalyst such as baking soda or vinegar. The electrolysis separates the two hydrogen molecules from the oxygen molecule and makes what is called oxyhydrogen, or HHO. The electrolysis reconfigures the water molecules to become the gas, which is then added to the air intake of the engine as an additive and in turn, your car has to burn less fuel to get better performance, cleaner exhaust, run cooler and the oxyhydrogen helps clean your engine’s internal components. Can you really ask for more from a cheap after market modification? I don’t think so.
So after learning about the basics, I ventured down to the hardware store. The materials were easy to find, and best of all cheap. I ended up spending less than $40 on the entire project. It took me about 5 hours to complete the fabrication of the system, and about another hour to install it into my car. It took my car which is a 1999 Buick Park Avenue, which averaged around 26 MPG before the HHO system, to about 46 MPG. My oil is almost as clean as I put it in when I change my oil. I also run premium fuel, so that also adds to the lack of particulates in the oil.
In conclusion, I’d just like to say that before you let the naysayers tell you it doesn’t work, is dangerous, or tell you that it can’t give you that much gain for all the work you have to do, take it from me. It’s a fun DIY project with possible big gains and you’re also helping the environment. It doesn’t take long at all, and I am confident that if you can check your own oil, you can do it yourself if you have the right resources and gumption.
