When I stumbled across the whole idea of making your car run on water, I was pretty intrigued by the whole thing. I did a little research and found that it really is possible.
I decided to test the main product on clickbank (water 4 gas) on my own car. My car is a Nissan 350z, which I have worked pretty hard for. It came straight out of what I make from my business. So needless to say I didn’t want to risk anything with it.
I got the list of parts from the Water 4 Gas guide, and (with the help of another person) managed to install everything in about an hour. The guide claims you can do it in much less time than that, but then I am not particularly good at technical stuff. The car does much better in terms of miles per gallon (not twice as much, but a significant improvement).
I wrote a water 4 gas review on my site with all the details.
