A. Yes, we seriously recommend it. First, adding water helps to keep your engine cool by ‘replacing’ the ‘cooling’ fuel mass that you have reduced; thus allowing an even leaner mixture. Second, the BG acts as a synergistic catalyst to release more energy from the fuel:water mixture than just adding water alone could accomplish.
See our “Super Gas Saver Secrets”, ‘HyZor Technology’ book, ‘Water Injection’ Manual and HyCO 2DT Manual for practical details on how to add Water Injection. See our “Water as Fuel” book to learn about other ways to add water.
