IIRC, Alaska has year-round ethanol free fuel because of it.

I realize this is an old thread but that is not why Alaska doesn't have to use Ethanol. Their senators lobbied and got an exemption (probably a trade for a vote somewhere else) because it costs a bunch more to move gas from Kansas up there where they are already swimming in domestically produced gas. The big argument for Ethanol was to increase the percentage of domestically produced fuel. Ethanol works just fine in the cold places of the world.
So from what I read the winter blends do have a tiny effect on economy, but the mileage hit most people see is from the cold temperature of nature, not from the fuel they use. The biggest hit is from the increased viscosity of oils and the longer enriched warm up times of the engine.
