The EPA use to mandate minimum proportion of oxygenates be added to automotive gasoline on regional and seasonal basis… Is that still going-on? This was done to reduce pollution during the winter months. I always noticed improved performance but mileage declined.

That and altitude make a huge difference. Anyone else here in aviation we know all about the cold weather!
