    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

      Also your tire pressure likely goes down, further hurting your mileage. Always remember to swap out the summer air in your tires for winter air.
