If you mean ethanol is hyroscopic it is it won't mix with gasoline unless it's chemically dried. Chemically drying ethanol is very expensive and very energy intensive and quite pointless ethanol fuel burns well enough with 2% water in it. If you leave E85 in an open container it will absorb water from the air and the gas will separate out. once its got that 2% its happy. In Brazil they sell ethanol 2% water (Alkohol in Portuguese) in every gas station and it's cheap really cheap.
