I drive a honda civic hybrid, and I'm wondering what kind of milage I should be getting in chicago with the snow and cold. What are you midwesterners getting on your recent tanks? I'm only getting about 34mpg. The last tank the mpg the computer reported was 38 but the calculations based on fuel put in and distance was 34. I know that the calculations won't be 100% correct based on how much fuel I put in each tank and stuff but is 34 or so way low for a hybrid at this time of year or is it near a typical result?

I drive 2 20 mile trips per day to and from work in suburban trafic.
