#1  Maintain your vehicle. Regular service and maintenance will
              make it run more efficiently and use less gas. Change the air
              filter, put enough air in the tires, and get your engine well
              maintained.

        #2  Drive less during peak traffic. A lot of exhaust is emitted just
              sitting in traffic. Take public transportation, ride in a carpool,
              change your schedule to miss traffic, or walk and ride a bicycle
              more often to save gas and emit less CO₂.

        #3  Drive the limit. Don't speed! You will emit less just by
              not speeding. Driving the speed limit saves gas. Fuel efficiency
              goes down considerable as you go faster than 65 mph and
              significantly drops above 70mph.

        #4  Skip all drive-through. Sitting idle is not an efficient use of a
              gallon of gas.

        #5  Start and go. Most new engines don't need to 'warm up'
              anymore.

        #6  Plan ahead to minimize cold engine starts by going places that
              are near one another when you run errands.

        #7  Pick up speed at a moderate pace.

        #8  Lighten your load. Empty any unnecessary weight to get better
              gas mileage.

        #9  Moderate using the AC and defroster, both reduce fuel
              economy.

       
Two additional fuel economy tips for hybrid vehicle drivers:

        #1  Judge traffic flow and glide to a stop and avoid a hard stops.

        #2  In stop and go traffic, accelerate to your desired speed and
              maintain it using electric power as long as you can without
              engaging the gasoline engine.
