Its interesting that the non-ethanol stuff is more expensive, because my understanding is that the cost to produce a gallon of Ethanol is somewhere in the $8 to $10 range. As a boat owner, I'm continuously battling the affects of ethanol. Regardless of whether its 10%, 15%, phase separation, or what it costs to produce, the bottom line is that older (by older, I'll say roughly pre-2002-2003) engines/fuel systems (in cars, boats, trucks, bikes, lawn equipment, etc...) are not designed to "handle" ethanol. Its alcohol. And alcohol will dry up rubber components over time. So all those older fuel lines will slowly, but oh-so-surely, deteriorate in time. There are no places anywhere near me that are Ethanol free. Although it would pain me, I would probably pay $1 more per gallon if I could get it.
