Tips From AAA And Consumer Reports On Getting Better Gas Mileage

As gas prices gradually decline, consumers should consider enhancing fuel efficiency by changing their driving habits. It's uncertain when prices might increase again.

“It’s a hard reality to accept, isn’t it? You have to fill up with gas to get through your day—going to work and picking up the kids," said Michael Crossen, auto testing manager at Consumer Reports.

7 Tips to Save Fuel in Massachusetts

1. Reduce your speed or turn on cruise control.

Vehicles are most fuel-efficient at specific highway speeds, as Sean Tucker of Kelley Blue Book explains. "Maintain a speed of 65 mph (105 kph) on the highway,” Tucker recommends. "Modern cars perform best at that speed, and going faster can noticeably decrease fuel economy." Research suggests that lowering speed can improve gas mileage by as much as 14%.

If you're finding it difficult, using cruise control can be beneficial. It maintains a constant speed, reducing the need to hold the gas pedal continuously, and helps avoid sudden jerks or quick braking. Additionally, experts recommend coasting when approaching stoplights, whether the light is red or green but might change soon.

2. Limit idling

Experts suggest utilizing a vehicle’s automatic start-stop system. It automatically turns off the engine when idling at traffic lights and restarts it when the accelerator is pressed. David Bennett, AAA's senior automotive manager, states, "If you're stuck in traffic for a while and have start-stop enabled, don’t disable it." He recommends allowing the engine to turn on and off as needed, particularly when air conditioning isn’t required during extended stops.

3. Lower your vehicle's aerodynamic drag and eliminate excess weight.

Many drivers attach roof or bike racks to their vehicles, which increase wind resistance and can lower fuel efficiency by several miles per gallon. Crossen mentioned, "If you’re not using those racks, it’s like towing a parachute behind your car. Any accessory that increases drag should be removed." If you’re carrying heavy items in your back seat, trunk, or truck bed that aren’t needed, it's better to leave them at home.

4. Inspect your tire pressure and carry out additional maintenance tasks.

Experts highlight the importance of maintaining tires at the recommended pressure specified in your vehicle’s manual. It’s advised to check tire pressure every other fuel stop. Bennett points out that under-inflated tires increase road resistance, leading to less smooth handling and slower acceleration. Keeping tires properly inflated can enhance driving comfort and fuel efficiency, potentially boosting gas mileage by up to 10%.

Auto repair shops frequently perform straightforward adjustments to boost a vehicle’s fuel efficiency. Tucker suggested, “If you’re not achieving the expected fuel economy, it's time to visit a mechanic.” These adjustments may involve replacing parts like the air filter or oxygen sensors, which assist the engine in determining the correct fuel mixture.

5. Consider coordinating ride-sharing and trip merging.

Whenever feasible, carpool and share costs with others. Plan trips carefully to reduce the total number of outings. Avoid unnecessary stops and refrain from driving across town just to save a few cents on eggs, as Crossen suggested. Be deliberate with your outings, and drive only when it’s genuinely needed.

6. What kind of fuel are you buying, and at which location?

Some vehicles need premium gasoline, and experts advise using it when required. However, many drivers opt for premium even when it's not essential, only to discover that regular gas performs just as effectively. Whatever octane level you select, pay attention to your fuel's quality. Check if your local station offers "Top Tier" gasoline, which has additives that help reduce carbon buildup in your engine.

During times of high prices or shortages, keeping a full tank isn't necessary but can be beneficial. Apps like GasBuddy (my preferred choice) help compare local fuel prices or those along your route home. Experts recommend filling up when your tank is around half full, providing flexibility to wait for cheaper prices.

7. If you're considering a new car, consider opting for a hybrid.

Currently, the average age of vehicles on the road is around 12 years, and newer cars typically offer better fuel efficiency than older models. Not everyone can afford a new vehicle, but those shopping for a car might think about a hybrid as a stepping stone before fully switching to electric. For those ready to go entirely gas-free, electric vehicles—including many used options—are easily accessible.
