You can save some gas by turning your engine off at long red lights or at drive thru's. In my commute I usually have to wait a few minutes at a specific stop light. I turn my engine off while waiting for the green light. I can tell when the light is about to turn green by watching the crosswalk sign. When the crosswalk sign starts blinking to not cross, then I restart the engine. Saves about two minutes of idling (at zero mpg!). I also turn off the engine while I'm waiting at a drive through like at my bank. Improves my gas mileage by at least 1mpg.
