Anyone interested in the compatibility of hydrated ethanol with
gasoline might want to look at Figure 14-14 on p 357 of David Blume's
"Alcohol Can Be A Gas". The figure is entitled
"Fuel Compatibility Among Water, Ethanol, and Gasoline." It is a diagram
produced by the Society of Automotive Engineers.
It indicates that:
- at about 68F (20C), alcohol with as much as 45% water will mix with
gasoline and NOT
separate.
- 80% ethanol:20% water will not separate from gasoline down to about
14F (-10C)
- at 4% water, alcohol will form a stable mix with gasoline down to
about 122F (-38C)
