If ethanol is "completely soluble in motor gasoline" why does it have a tendency to separate as it ages and as atmospheric changes occur? The EAA notes this: Ethanol tends to develop "phase separation" as the aircraft climbs, the resulting water (that was held by the ethanol) could overwhelm fuel filters/sediment bowls.
Those liquids that are truely soluble do not separate in this way. Frank Nelson --- In [email protected], "va_couper" <[EMAIL PROTECTED]> wrote: > > Ethanol is completely soluble in motor gasoline.
