I read the Water 4 Gas Review about a month ago and it was helpful in allowing me to choose and purchase a water fuel conversion kit. I am just about sick over the talk about gas prices going even higher this summer as the price of oil grows and grows. The review helped me to pick a conversion kit. I had my brother install it in my SUV and so far so good. My mileage has improved by over 40% and the exhaust coming out of my tailpipe looks and smells a lot cleaner. I am saving money on gas every week.
