I haven't done any calculations yet, but I can tell my mileage has been crap all winter. But, I also run my tires in the 30 PSI range to get more surface area contact (I usually run over 40 PSI). I'm only idling a couple minutes each morning to scrape all the ice and snow off, so I'm chalking up the bad MPG to the winter fuel mix and low tire PSI.
