Rising pump prices make it smart to get the most miles from each fill. These seven practical changes can improve fuel economy and reduce trips to the station.
1) Obey speed limits
Fuel efficiency typically drops at speeds above about 50 mph. The Department of Energy notes that each 5 mph over 50 is roughly like paying an extra $0.27 per gallon. Slowing to posted limits saves fuel and lowers the risk of a ticket.
2) Drive conservatively
Avoid rapid acceleration and hard braking. Aggressive driving can cut fuel economy by 15–40%. Smooth, steady acceleration, anticipating traffic, and minimizing stops will raise miles per gallon and reduce wear. Use cruise control on long, dry highway stretches to keep a constant speed.
3) Keep tires properly inflated
Underinflated tires increase rolling resistance and force your engine to work harder. Tires typically lose about 1–3 psi per month and more in cold weather or with minor leaks. Check pressures regularly and inflate to the manufacturer’s recommended psi (usually on a sticker inside the driver’s door) to protect fuel economy and tire life.
4) Minimize idling
Idling longer than about 10 seconds consumes more fuel than restarting. Modern engines warm up faster when driven, so long warm-ups aren’t necessary—about 30 seconds is usually sufficient. Turn the engine off when it’s safe instead of letting it idle.
5) Combine trips
Fewer cold starts and consolidated errands save fuel. Plan efficient routes, run multiple errands in one outing, and group appointments. Short trips are especially costly because engines are less efficient until they reach operating temperature.
6) Watch your cargo
Extra weight reduces fuel economy—roughly 1% for every 100 pounds. Roof racks and cargo boxes add aerodynamic drag; a rooftop box can cut fuel economy 2–8% in city driving and up to 25% on the highway. Remove unused racks and carry heavy items inside or use a rear-mounted option when possible.
7) Use climate control wisely
Air conditioning can increase fuel use by up to about 10%, while open windows create drag at higher speeds. At lower speeds (below roughly 45 mph), open windows are typically more efficient; above that, close the windows and use A/C for better overall economy.
Bottom line
You don’t need a new vehicle to cut fuel costs. Slowing down, driving smoothly, maintaining tire pressure, minimizing idling, combining errands, reducing extra weight, and managing A/C versus open windows can all add meaningful miles per tank, save money, and lower emissions.
