Studies have shown that you use 30% more gas by going 70 mph rather than going 60 mph.  So – save money by slowing down.  Use your cruise control – a steady speed will reduce gas consumption.  Idling more than 10 seconds wastes more gas than turning the engine on and off, so if you are going to sit there shut the car off.  Bunch your errands together rather than having to make multiple trips out and try to arrange them to make as many right hand turns as possible.  UPS saved millions of dollars in one year by not having to sit at red lights waiting to make left hand turns.  You cannot save millions but maybe hundreds or thousands.
