One thing I have noticed is that at lower temperatures(<40F) the engine seems to idle at a higher speed(~2000 rpm) for the first 5 or 6 minutes after first start up. I think this is for the oil or the O2 sensor to reach operating temperature.
My MPG decreased last winter too - I'm guessing it is because of the higher idle speed and the winter blend.
