Now I am now getting a 50% increase in mpg in my car

I found this website the other day, which claims that you could use water as a fuel in your car, not putting into the gas tank at using water, fuel cells and installing them under the hood of your car.  So I had to find out whether run your car with water scam Well after a lot of reading, I found out that it is not a scam and a catchy bite these things on eBay now. So I ordered a water fuel cell and installed it on my car.  I can’t believe it’s I am now getting a 50% increase in mpg.
