Cold weather = bad gas mileage?

Did that have anything to do with it? Do I have a bad thermostat or is the engine running that cool when around town? Coming off the highway it stays warm.
Fluid level is good also.

Check your coolant temps via logger. You should still get to operating temperatures, but you could have a failing t-stat.
