10. Avoid being heavy-footed when it comes to either the gas or brake. Smooth, steady acceleration and gradual braking can help your engine operate more efficiently. Tailgating may also increase the frequency in which you will find yourself needing to slam on the brakes, so keep a safe distance between you and the vehicle in front of you.
11. Use your GPS to program the route you plan to take to your intended destination. You’ll likely reduce the chances of being stuck in stop-and-go traffic by using your GPS or in-vehicle navigation to help you map your route. Major traffic jams and accidents can potentially be avoided as well. By using your GPS, you may be able to use less gas, spend less time idling and arrive at your destination faster.
12. Combine trips. If you have to run errands, or go to more than one destination, try to do so all in one trip. Combining trips minimizes your driving time, allows you to use less fuel, and generates less harmful emissions. Try to avoid city streets and opt for highways (where speeds are more stable, rather than stop-and-go) to improve fuel efficiency.
