There are a number of companies which make a gadget you can attach to the air intake of your car which injects a mixture of hyrdrogen and oxygen derived from electrolysis of water, into your engine.
They claim it improves the efficiency of your engine and will increase gas mileage by about 30%.
Has anyone tried it? What are the results?
