The problem with ethanol is how it reacts to water in the air and in the tank. Ethanol can mix with water, while gasoline and water do not mix. Ethanol and gasoline can mix, but if the water concentration in the ethanol is too great, it can separate the ethanol and water from the gasoline. This is called phase separation. If the phase separation occurs inside the gas tank, the ethanol and water mix falls to the bottom of the tank, resulting in the pump (IN-TANK ELECTRIC) bathing in this corrosive mixture. The phase separation issue might only be an issue with vehicles that sit for long periods or have EVAP issues.

Phase separation can also occur under conditions where the fuel tank is open to the outside air. On carbureted engines, phase separation can occur in the bowls. It is typically seen as blue or white crystals. Copper and bronze do not stand up well to corrosion in the first place. Since copper and bronze are used in electric fuel pumps and the coils in the injectors, corrosion can be an issue. For a carbureted vehicle, the blended mixture can react with floats, jets and even the pot metals and aluminum.

So I have a place not too far away from where I live (Murphy's Gas, at a Walmart on the Interstate) that sells non-Ethanol gas. Would there be anything about this gas (i.e. other 'modern' additives) that will adversely affect my carberetored fuel delivery system? My thinking is if I pony up the extra bucks for non-Ethanol fuel, I can eliminate the problems associated with today's modern fuels. Fact or falacy?

I use non-ethanol gasoline in my '55 and add fuel stabilizer occasionally.
