The whole ethanol idea IMHO, is crazy. It essentially takes more energy to produce it, than it provides. It taps into our food sources which eventually will come back to bite us. The gasoline goes bad faster, at least on a carbureted car ...I used to go work on cars that had been sitting for a couple of years. I'd find the problem, then fire it up, and usually the thing would run on the gas that had been sitting in the tank (although it would smell rank).... Now, you let one sit 6 months to a year, and there's a good probability that your gonna have to pull the carb and clean it and drain the tank. My buddy has 6 older 70's trucks that do a lot of sitting. Even using Sta-bil in the gas, he's constantly re-working the fuel systems. He could let them sit for long periods of time when the fuel you bought was predominately ethanol free (although, yes E free gas will go bad too...just takes a lot longer). My motorcycle runs better and gets better MPG with non Ethanol gas as well. I fear that eventually you wont be able to buy E free gas. For me, it's worth the extra $ for E free fuel in my older vehicles.
IMHO, ethanol is for drinking, not as a cutting agent to make the oil companies crude go further.
