I have friends that have installed a hydrogen generator to their motorhome. He is a chemical engineer. There gas mileage has doubled. Has anyone used a hydrogen generator in their diesel motorhome? What are your thoughts and experiences with a hydrogen generator? My folks still have an old Lincoln Towncar and they get 22 MPG. Engines can be made to give better gas mileage, it appears. Why don't they? Linda Adels Montgomery, Tx
