You can use less fuel without changing your commute or schedule by checking tire pressure, removing unnecessary cargo, keeping up with scheduled maintenance, and making a few low-effort adjustments while driving. The size of any savings depends on your vehicle and conditions; no single step guarantees a fixed improvement.
Start with checks that barely affect your routine
Set tire pressure to the vehicle’s recommendation
Check the pressure when the tires are cold and use the figure on the vehicle’s tire-information placard or in the owner’s information. The placard is commonly on the driver-side door area; some vehicles place it elsewhere. Do not use the maximum pressure molded into the tire sidewall as the target—that figure is not the vehicle maker’s recommended operating pressure. EPA guidance explains where to find vehicle-specific pressure information: Discover Fuel-Saving Tips.

Under-inflation can reduce fuel economy. The U.S. Department of Energy gives a general estimate of a 0.2% drop in gas mileage for every 1 psi drop in average tire pressure. That estimate is not a guaranteed result for an individual vehicle; use it as a reason to check pressure, not as a prediction of your savings. See DOE’s Tips For Your Tank This Summer Driving Season.
Remove things the car does not need
Take out unused heavy items and remove roof-rack accessories when you are not carrying something. Extra weight takes energy to move, while roof equipment can increase aerodynamic drag, especially at highway speeds. You can keep your usual trip and simply clear out gear that has been riding along unnecessarily.

Keep maintenance on schedule
Follow the maintenance schedule in your owner’s information and use the oil grade recommended for your vehicle. A genuine mechanical problem can hurt fuel economy, but routine service is not a guaranteed mileage upgrade for a car that is already operating properly. DOE notes that repairing a serious fault such as a faulty oxygen sensor could improve mileage by at least 40%; that example concerns a serious fault, not an expected gain from ordinary maintenance.
Make small changes during trips you already take
Avoid unnecessary extended idling
If you are waiting for more than a brief moment and can safely switch off the engine, avoid leaving it running for an extended period. DOE estimates that idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air-conditioning use. That is an illustrative range, not a precise rate for every car or situation.

Drive smoothly within the flow of traffic
Where traffic and road conditions allow, anticipate stops, ease into acceleration, and brake progressively rather than rushing toward a stop. On suitable highway stretches, a steadier pace can avoid unnecessary fuel use. Do not drive below a safe speed for the traffic around you, speed, or compromise attention and safe following distance to pursue economy. EPA identifies speed and smooth acceleration and braking among the factors drivers can control: Your Mileage May Vary.

Cruise control can help maintain a steady speed on an open, relatively level highway when conditions are suitable and the vehicle supports the feature. It is not appropriate for every road: stay in control and be ready to slow down for traffic, weather, hills, or changing conditions. EPA includes cruise control among the driving factors that can affect fuel economy.

Try eco mode if your vehicle has it
Some vehicles offer an eco mode that adjusts how the vehicle responds to support more efficient driving. Availability and operation vary by model, so check the owner’s information. Use it only when it suits the road and traffic; it does not replace safe driving or vehicle-specific guidance.

Actually, your mileage will vary: vehicle type and condition, maintenance, driving style, route, traffic, weather, and other factors all affect fuel economy. EPA summarizes this point in Your Mileage May Vary and its transportation FAQ.
Do not judge a change from one unusually short trip. Compare fuel economy over several fill-ups and try to make the comparison meaningful by using similar routes and driving conditions when possible. A single tank can be influenced by traffic, temperature, trip length, and how the vehicle was driven; trends over time offer a more useful indication than one result.
