My aunt called me up last week out of the blue to ask a me a question about some of the best gas saving products. She had seen an information commercial, and she wanted to know if what she saw about running you car off of water would replace your gas costs. I enlightened her and let her know that the whole concept of running you car with the help of water would not replace the gasoline in the car but by using the car’s battery and water you can improve you car’s efficiency and get more miles to the gallon and in a sense save gas.
