I have heard that the fuel ethanol that is sold in Brazil is not dehydrated (water removed). In the United States, the ethanol is dried, so that they can put gasoline in solution. Once you reach a certain level of water in solution, gasoline will separate. And the water in the ethanol can create higher corrosive conditions.

I don't know how accurate that information is, just heard it.

What does fuel ethanol sell for in Brazil?
I will have to convert the currancy.
In the U.S. E85 is about $2.30/gallon, and finding a supplier of high percentage fuel ethanol (E98) is not easy and I am not aware of any within 100 miles of me.
