Another thing to consider is you run your defroster more in the winter, and the defroster uses the A/C, which will rob you of power.
I try to remember and turn mine to floor or vent if ice/fogging on the windshield isn't a problem.
I get 300 miles or more in the summer, and a little less in the winter.
