You can often improve fuel economy in the car you already own by driving smoothly, keeping tires at the correct pressure, cutting unnecessary weight and drag, and following the manufacturer’s maintenance schedule. The best starting points are free; actual results depend on your vehicle, route, weather, and driving habits.
Start with driving habits
Accelerate and brake smoothly
Ease into acceleration, leave enough room to anticipate traffic, and coast toward stops when it is safe. Repeated hard acceleration and braking waste fuel. The U.S. Department of Energy (DOE) estimates aggressive driving may lower mileage by roughly 15%–30% at highway speeds and 10%–40% in stop-and-go traffic. Those are broad estimates, not a forecast for a particular driver or car. DOE’s Consumer Guide to Fuel Economy provides the agency’s broader guidance.
Keep highway speed in check
Fuel economy usually drops rapidly above 50 mph, according to DOE, though the most efficient speed varies by vehicle. Where traffic and road conditions allow, avoid unnecessary high speeds and use cruise control only when it helps maintain a steady pace safely.
Reduce idling and combine trips
Switch off the engine rather than letting it run while parked or waiting when it is safe and practical to do so. DOE estimates idling can use about one-quarter to one-half gallon per hour, depending on engine size and air-conditioning use; your vehicle’s actual consumption will vary. Combine nearby errands and plan routes to reduce backtracking. The Federal Trade Commission (FTC) says several short trips from a cold start can use twice as much fuel as one same-distance trip with a warm engine. FTC guidance on stretching gas dollars discusses trip planning and other ways to save.

Check tire pressure monthly
Check every tire, including the spare, at least once a month when the tires are cold. NHTSA defines “cold” as a car that has not been driven for at least three hours. Use the recommended pressure on the vehicle’s tire-and-loading label, usually near the driver-side door, or in the owner’s manual. Do not use the maximum pressure printed on the tire sidewall as your target: that is not necessarily the vehicle manufacturer’s recommended pressure.
A tire-pressure monitoring system (TPMS) warning is useful, but it does not replace regular checks. A basic pressure gauge can help you check accurately. See NHTSA’s TireWise tire guidance for its cold-tire procedure.

Reduce unnecessary weight and aerodynamic drag
Remove heavy items you do not need from the car and take off roof or bicycle racks when they are not in use. DOE estimates an extra 100 pounds could reduce fuel economy by around 1%, with the effect depending on the vehicle’s weight. Natural Resources Canada (NRCan) says roof-rack drag can increase highway fuel consumption by as much as 20%. These figures are context-dependent estimates, not guaranteed savings for every car or trip. NRCan’s fuel-efficient driving techniques cover racks, cargo, and trip planning.
Maintain the car to its manufacturer’s schedule
Follow the service schedule in the owner’s manual and address serious faults promptly. Use the motor-oil grade specified for your vehicle; DOE notes that using the recommended grade can save fuel. The effect of any particular repair on mileage depends on the fault and vehicle, so a repair should be based on the car’s needs rather than a promised universal MPG gain. DOE’s summer driving tips also cover maintenance, tires, oil, and idling.

Do not replace an air filter or request a tune-up solely for fuel economy without checking the vehicle’s service requirements and diagnosing a problem. The FTC warns consumers to be skeptical of products making extraordinary “gas-saving” claims. Avoid fuel-line magnets, generic plug-in gadgets, additives, and engine modifications unless credible evidence supports their use for your specific vehicle.
Think carefully before replacing tires
If your tires are due for replacement, low-rolling-resistance models may be worth comparing. NHTSA estimates that a 10% reduction in tire rolling resistance would improve fuel economy by 1%–2%; it is a general estimate, not a promise for a particular tire purchase. Compare compatibility with your vehicle, safety characteristics, fuel-efficiency evidence, expected tread life, warranty, and total price. Do not discard safe, serviceable tires solely for a speculative fuel saving.

Choose air conditioning or open windows for the conditions
Air conditioning uses energy, while open windows can increase aerodynamic drag. The balance depends on the vehicle, speed, outside temperature, and other conditions. Ontario’s driver handbook says that at high speeds air conditioning is usually more efficient than open windows; NRCan says air conditioning can increase fuel consumption by as much as 20% in some conditions. Neither statement makes one choice best for every trip. Consider speed and cabin comfort rather than following a universal “windows down” or “AC always” rule.
Track whether your changes help
Fuel economy varies with route, traffic, weather, and driving pattern, so one tank may not reveal the effect of a change. If you want to compare, record the fuel added and distance driven across several fill-ups under reasonably similar conditions, and note any major changes such as a different route or season. Treat agency percentages as context, not guaranteed personal savings. DOE’s guide includes dollar examples based on U.S. gasoline prices from December 2021; those figures should not be treated as current savings.
