    Idk the science of it but only what I have observed. I live somewhere where it is ~20°F in winter and ~85°F in the summer. In winter I avg around 21MPG and in the summer I avg 23MPG.

      The difference in gas mileage is almost certainly due to winter blend fuel, which has a lower energy density than summer blend.

      with such a cold weather, the engine is going to take a while to reach ideal operational temperature, so running un-efficiently for a while. MPG change will be more noticeable if your commutes are short
