Is Water4gas The Best Manual?
I have bought water4gas, run your car on water, and half gas half water and some others not worth mentioning. I actually help install the kits and realize a bit of unique in each. water4gas is pretty complete, but quite technical, as is half water half gas. runyour car on water is an easier read I would say. You can see a full review of the better ones here http://waterpetrolcar.com
