What happens when phase seperation occurs?
Several things happen: • The ethanol and water molecules settle to the bottom of the fuel tank, forming a distinct layer of water and ethanol on the bottom and pure gas on top. • Fuel for the engine is drawn from the bottom of the tank. An engine will not run properly (if at all) on a mixture of ethanol and water. The ethanol and water mixture is very corrosive to some metals and can damage internal components. • The remaining gasoline, without ethanol will have an octane level below the origional E10 fuel’s octane level, approximatly 2-3 octane lower. This octane level may be below the requirements of the engine.
