Drive at a consistent speed. Frequently changing your speed can decrease your fuel efficiency.
Stop speeding. Your Dodge Durango uses fuel most efficiently when you are going under 60 miles per hour. Anything about that eats away at the gas much more quickly.
Decrease the weight. If you have extra stuff in your car, get rid of it. The lighter your car is, the less fuel that is needed to move it.
Stop idling. There is no need to waste gas when your vehicle isn't moving.
Tune your engine. A properly tuned engine allows your vehicle to run more efficiently.
Inflate your tires. As your tires become deflated, it puts more stress on your vehicle and makes it work harder and use more gas to go the same distance.
Add oil. If your car is running low on oil, or you're using a cheap oil, your car will have a lower MPG. Make sure you check your oil regularly.
