While it is possible, it is highly unlikely to happen because it would require a lot of time. Here is quote from an EPA report on phase separation in oxygenated fuels.<BR/><BR/>"For example, at a constant temperature of 100 degrees F and relative humidity of 100%, it would take well over 200 days to saturate one gallon of gasoline in an open gasoline can (assuming the only source of water is water vapor from the air). Water absorption from the air is far slower at lower temperatures and humidities. (At a temperature of 70 degrees and relative humidity of 70%, it would take over two years to saturate one gallon of conventional gasoline in the same gasoline can.) Again, oxygenated gasolines can hold more water than conventional gasoline, and would therefore take much longer to saturate with water."<BR/><BR/><A HREF="http://www.epa.gov/otaq/regs/fuels/rfg/waterphs.pdf" REL="nofollow">Water Phase Separation in Oxygenated Gasoline</A>Michael A.
