Remove extra weight from your vehicle

Keeping the weight of your vehicle as low as possible is one way to save on fuel expenses, so clear out your trunk as soon as you can. An additional 100 pounds of added weight can decrease fuel efficiency by 1% (opens in new tab). Additionally, if you drive a smaller vehicle, having extra weight in your car will impact you more than if you drove a larger car. 

This goes for carrying cargo on your roof as well. Having a cargo box on your car’s roof causes aerodynamic drag, which can lower fuel economy by  2%–8% in city driving, 6%–17% on the highway, and 10%–25% at Interstate speeds (opens in new tab) (65 mph–75 mph). If you have to carry luggage or equipment with you, opt for a rear-mount cargo box or tray.  

Slow down (and use cruise control)

Are you an aggressive driver? If you find yourself rapidly braking and accelerating, or often speeding, you could be lowering your gas mileage by up to 33% at highway speeds, 10% to 40% in stop-and-go traffic, or by 5% around town (opens in new tab). To maximize fuel efficiency, accelerate gradually and avoid any unnecessary braking. Keep your distance from other cars and coast to stops instead of mashing the brakes. An easy way to maintain a consistent speed is by using your car’s cruise control. 

Furthermore, driving the speed limit can increase your gas mileage. Generally, for every 5 mph you drive over 50 mph, you'll pay an additional $0.18 per gallon for gas (opens in new tab). Therefore, it’s recommended to stay as close to the speed limit as possible if you’re looking to save the most money. Plus, it’s safer anyway.  

Don't let your car idle

While it may seem more fuel efficient than having to restart your engine, leaving your car idling is actually wasting more fuel than you think. In fact, depending on your vehicle, if you leave your car idling for an hour you could be using a quarter to a half gallon of fuel (opens in new tab).

To cut back on fuel usage, some newer cars have features that turn off the engine when the brakes are used. If your car has this feature, make sure it’s enabled to help you maximize fuel efficiency. If not, be sure to turn off your car the next time you leave your vehicle, instead of leaving it idling. Even if it's just to run inside and grab something you forgot. It could save $0.01–$0.02 (opens in new tab) per minute.  

Make sure you have the right tire pressure

Keeping your car in great condition can help you save money on gas over time. For one, it’s important to make sure your vehicle has proper tire pressure. By keeping your tires at the proper PSI, you could improve your gas mileage by up to 3.3% (opens in new tab). Don’t wait until your tire pressure light comes on, however, as gas mileage decreases by 0.3% (opens in new tab) for every 1 PSI drop in pressure of all four tires. 

Use the proper motor oil for your vehicle

Another way to maximize fuel efficiency is to use the proper grade of motor oil for your vehicle. In fact, it can raise your gas mileage by 1-2%. (opens in new tab) If you're engine is out of tune or fails an emission test, you can improve mileage by 4% (opens in new tab) by having these problems fixed.
