Run your car on water

I have seen several sites that promote running your can on water by converting it to H and O with a kit. You then inject some of the H with the gasoline. Your mileage then jumps. I suspect a scam. What does anyone else think?

Put your money on the ponies instead. You’ll have more fun and stand a better chance of getting a return.

How many times per day does this come up? More than I can count.

It’s a scam!

Why are so many people willing to hope otherwise?
