Well, for all the trips going to school, I start the car, and spend about 1 minute clearing off the windows, as there's been frost on them every day. For the trips from school, I start the car, and leave, as the windows have been clear every day.

Next year, I'll try to get a block heater, and compare the results. I'm sure that they will be much higher, as engine warmup is probably the main factor for poor mileage in the cold. There's not much point in getting a block heater now though, as winter here is pretty much over.

Once the engine is warmed up though, the coasting mileage is still worse at low temperatures than it is at high temperatures. Obviously, there are other factors, like wind, but on colder days, my mileage at 55MPH is definitely worse than it is on warmer days.
