12 Driving Tips for Better Gas Mileage - Hypermiling
1. Coast as much as possible. Look ahead for any stops or slow downs in traffic coming up and immediately take your foot off the accelerator. The more constant you keep your speed the better your mileage.
2. Keep your speed below 55 mph. For every 5 miles you drive above 55 you lose about 10% of your fuel economy.
3. Avoid routes with lots of traffic and stop signs/stop lights. A longer route with fewer stops may be more fuel efficient.
4. If your job has flexible hours try going in earlier or later to avoid traffic.
5. Change your oil every 3000 miles. Newer oil is thinner and gets pushed through the engine easier, thus increasing fuel mileage.
6. If idling for more than a minute turn off your engine.

7. Don’t stomp the gas pedal. The more gradually you press it the better your mileage. Allow yourself a few more seconds to get to cruising speed.
8. Use cruise control. This keeps speed more even and prevents “speed creep” or a tendency to gradually increase one’s speed.
9. If driving a automatic let your vehicle begin to roll forward on its own after starting. Moving forward from a dead stop takes a lot of fuel.
10. Leave a buffer between you and the car in front of you to reduce sudden stops.
11. When approaching a stale green light begin slowing down to avoid a sudden stop.
12. Look for upcoming downward hills and take your foot off the accelerator before you get to the top then coast down the hill.
