I managed to get over 52 MPG on my 12 Civic......on a carefully driven trip one time. I certainly can't get that on my daily commute.
My daily mileage dropped from 34 MPG to a bit over 28 MPG, solely because of the switch to winter blend gasoline and colder weather.
Aside from that, make sure your tires are aired up properly and use Top Tier Gas. http://www.toptiergas.com/retailers.html
Cold weather driving sucks a lot more fuel too.
