5. Don’t Haul Cargo on Your Roof
According to the U.S. Department of Energy, hauling cargo on your roof makes your car less aerodynamic, which means it’s less fuel-efficient.
Rather than hauling cargo on your roof, try hauling it on the back of your car. A cargo box on your roof can reduce your fuel economy by between 2 and 8 percent in cities, between 6 and 17 percent on highways, and between 10 and 25 percent on interstates.
Meanwhile, a rear-mounted cargo box only reduces your fuel economy by between 1 and 2 percent in cities and between 1 and 5 percent on highways. Fuel economy information on rear-mounted cargo boxes is not available for interstates
6. Use Your Cruise Control
Making use of your cruise control can help you save money on gas. As we mentioned, reducing your driving speed can help improve your fuel economy. Cruise control can help you do that more consistently.
7. Practice Smooth Braking and Accelerating
Fast braking and acceleration can cause wear and tear on your vehicle and reduce your car’s fuel economy. In fact, aggressive driving can lower your gas mileage by as much as 15 to 30 percent on highways and 10 to 40 percent in cities.
As an added bonus, improving your braking and acceleration can help you save money. Many insurance companies offer discounts to safe drivers. These companies track your driving habits and then reward you if you meet certain standards. An example is Allstate’s Drivewise program.
8. Properly Maintain Your Car
Regular car maintenance is another strategy for eco-friendly driving. Steps such as getting regular oil changes, changing your oil filters, and getting regular engine tune-ups improve your fuel efficiency.
9. Reduce Extra Weight on Your Vehicle
Excess weight on your vehicle can reduce its fuel efficiency. According to the U.S. Department of Energy, every extra 100 pounds in your vehicle reduces your miles per gallon by roughly 1 percent. While extra weight in your vehicle isn’t always avoidable, you can be more thoughtful about driving with heavy objects in your car unnecessarily.
10. Use Your Car’s Eco Mode
Many cars have an eco mode that reduces your car’s engine output, which improves its fuel economy. Turning on this eco mode will help you to get more miles per gallon and reduce the amount you spend on gas.
