The size of any improvement depends on your vehicle, driving and its condition; published estimates are not guarantees for an individual car.
Which driving habits can improve gas mileage?
Accelerate and brake smoothly
Rapid acceleration, speeding and hard braking use more fuel than steady driving. The U.S. Department of Energy (DOE) says aggressive driving can lower gas mileage by up to 30% at highway speeds and up to 40% in stop-and-go traffic. Those are upper-end estimates, not a promise of savings for every driver. Leave room to anticipate traffic, ease into acceleration and coast toward a stop when it is safe to do so. Smoother driving can also reduce abrupt maneuvers.
Choose a sensible speed
Fuel economy generally falls as speed rises, and the DOE says average fuel economy usually decreases rapidly above 50 mph. That is not a recommended speed or a universal optimum: each vehicle has its own most efficient speed or range. Follow posted limits and drive at a safe speed for road and weather conditions rather than slowing to a fixed number in every situation. DOE’s driving and fuel-economy guidance explains these estimates.
Cut unnecessary idling
Idling can use about a quarter to a half gallon of fuel per hour, depending on engine size and air-conditioning use, according to DOE. For a personal vehicle, DOE’s Alternative Fuels Data Center advises shutting the engine off when parked or stopped for more than 10 seconds, except in traffic. Never switch off where traffic conditions, safety, vehicle instructions or the need to keep the vehicle ready to move make it inappropriate.

Remove cargo you do not need
Take out tools, equipment and other heavy items that do not need to travel with you. DOE’s Consumer Guide estimates that an extra 100 pounds could reduce fuel economy by around 1%, with a larger proportional effect on smaller vehicles. Roof cargo is particularly worth removing when not in use: carrying it adds weight and can increase aerodynamic drag.
How should you check tire pressure?
Underinflated tires can reduce fuel economy, and maintaining the correct pressure also supports tire safety. Check all tires, including the spare where applicable, at least monthly and when cold. NHTSA defines cold as not having driven the vehicle for at least three hours.

- Find the recommended pressure on the tire-and-loading information label on the driver’s door edge or post, or in the owner’s manual. Do not use the maximum pressure molded on the tire sidewall as the vehicle’s target.
- Use a tire pressure gauge to measure each tire while cold. A gauge makes the check; it does not save fuel by itself.
- If needed, adjust pressure to the vehicle manufacturer’s specification and check again. Repeat monthly, even if the vehicle has a tire-pressure monitoring system (TPMS).
DOE estimates that properly inflated tires can improve mileage by an average of 0.6% and by up to 3%; its estimate says each 1 psi shortfall across all four tires can reduce mileage by 0.2%. NHTSA’s TireWise guidance says proper inflation can save as much as 11 cents per gallon, an estimate that depends on fuel prices and its underlying assumptions. These figures are general estimates, not guaranteed savings. A TPMS is useful, but NHTSA still recommends monthly pressure checks. See NHTSA’s TireWise guidance for tire-care information.
What basic maintenance helps—and what it cannot promise
Follow the vehicle’s service schedule
Use the maintenance schedule in the owner’s manual and the oil grade specified by the manufacturer. Routine service helps keep the vehicle operating as intended, but an oil change or other scheduled service does not guarantee a particular MPG improvement. Do not shorten service intervals or rely on fuel additives as mileage fixes without a manufacturer-supported reason.

Investigate a real fault
If mileage drops unexpectedly or the vehicle has a warning light or other symptom, have the cause diagnosed rather than assuming routine maintenance will fix it. A faulty oxygen sensor is one example: DOE says repairing that fault can improve mileage substantially, estimating at least 40% in its 2022 article. That estimate concerns a diagnosed problem; it does not describe the gain from ordinary maintenance or apply to every vehicle.
Choose replacement tires for fit and safety
When tires are due for replacement, NHTSA says low-rolling-resistance tires can improve fuel economy. Keep vehicle fit, safety and the manufacturer’s size and load recommendations as priorities; do not choose an unsuitable tire solely to pursue a mileage estimate.

What improvement should you expect?
There is no universal ranking of these actions because their relevance depends on the vehicle and how it is used. Smoother driving, less avoidable idling and correct tire pressure are accessible steps for most drivers. Removing needless cargo is easy if the vehicle carries it; correcting a diagnosed fault may matter more, but the outcome depends on the fault. DOE’s Consumer Guide says studies suggest the average driver could improve fuel economy by roughly 10% through fuel-saving practices. Treat that as a broad estimate, not an individual forecast.
For the underlying estimates and guidance, consult the DOE’s 2022 fuel-saving tips, its Consumer Guide to Fuel Economy, the DOE Alternative Fuels Data Center’s idle-reduction guidance and NHTSA TireWise.
