this is from a few days back. I know from work stuff fueling stations are allowed to run higher RVP (Reid Vapor Pressure) fuels through the colder months. this is an upper limit not so much a minimum, but for CT/RI/NY there is a step up from summer fuels come middle September then again the beginning of November. this doesn't speak to detergents/additives and such but the chemicals added usually go towards increasing the volatility (RVP) and make it more combustible in the cold.
