The winter blended fuels include anti-gelling agents that effect the mileage. I see my mileage drop from 17 average to 15.5 in the winter.
Another factor for me is the warm up time- I don't like cold cars!
Unfortunately, the rest of my vehicles, with the exception of the Kubota are gas powered. Ethanol
