After reading the three books from water 4 gas, it's hard to call the water 4 gas system a scam. So much effort was put into testing the systems and providing information about it that it's hard to consider it anything but valuable.
I believe that some people are calling water for gas a scam because they expect more than a book. Visitors to the website more than likely quickly look at the pictures and expect a ready to go package to be delivered.
This is not the case; the books provide pictures and part numbers and places to buy the items needed to build your own system and instructions on how to install it.
After doing some research on the basic part of the system I have found that it operates very similar to alcohol injection kits that have been available for race cars for many years.
Alcohol injection kits can be very expensive, costing up to $ 600. The water for gas website has found a less expensive way to build and install a system that will increase fuel economy. Plus you can continue to expand the system at your own pace to further increase your miles per gallon.
Once installed in your vehicle, you'll notice a quiet, smoother ride in your vehicle as well. The water that converts into a gas, known as hydroxy, actually steam cleans your engine eliminating built-up corrosion. Some people who have already installed the water 4 gas system into there vehicles have reported an increase in gas mileage of 100-200% overall.
For under $ 200, your car can be upgraded to burn not only gas but water before prices climb from $ 4.00 a gallon to $ 7 or $ 8 dollars a gallon (which many countries in Europe are already seeing). Those who are unwilling to prepare for the future will suffer at the hands of the 'gas man'. My advice, be smart, prepare yourself and your family and friends.
