A failing O2 sensor can cause poor gas mileage... what do you usually get in terms of mpg? You can sometimes tell if it's the O2 sensor if you smell unburnt fuel in the exhaust fumes.

check o2 sensor. check the tire pressure. if you got a sub in the trunk take it out. excess weight causes low gas milege and TRY to drive the speed limit which I know is a hard thing to do haha.

The gas mileage is poor in winter comparing to summer. This is because the oil is more thick than normal. Replace also your air filter and check engine faults.
