You can save fuel 30% using hydrogen and oxygen from water in your car.

Do it yourself learn how to make and service your construction at :www.water4gas.co

 This saving of fuel may be up to 35% driving out of city and depends from your H-HO Cell. I started this project at 2009 with experiments on my car and became an expert of it. The basic theory is simple and based on electrolysis of water. at the construction there are many problems to solve e.g : An electrolysis cell produce a gas mixture of H and O but also produce and stem from temperature rise inside, this stem must be removed from product.Another problem is where you find the proper elements to construct.You may also buy  one kit from the owner and install  on your car.But you must learn how to repair and serve it to prevent problems on engine of your car. I wish you the best with love.................John.
