Learn practical strategies to reduce fuel consumption and save money on your driving expenses.
While open windows are more efficient than AC at low speeds, they create significant aerodynamic drag at highway speeds above 45 mph. At higher speeds, the wind resistance from open windows reduces fuel economy more than using air conditioning. For highway driving, close windows and use AC moderately for better fuel efficiency.
Plan multiple errands in a single outing rather than making separate trips throughout the day. Cold starts use more fuel than when the engine is already warm. Combining trips reduces total mileage and saves fuel by keeping your engine at optimal operating temperature.
Choose motor oil that matches your vehicle manufacturer's recommended grade and viscosity. Using the correct oil reduces engine friction and can improve fuel economy by 1-2%. Look for oils labeled "Energy Conserving" on the API performance symbol for additional fuel-saving benefits.
Gasoline expands in heat and contracts when cooler. Fill your tank early in the morning or late evening when temperatures are lower to get slightly more fuel for your money. Additionally, avoid topping off after the pump clicks—this wastes fuel through evaporation.
Fuel economy decreases significantly at speeds above 50 mph. Every 5 mph over 50 is like paying an extra $0.18 per gallon. Driving at moderate highway speeds can improve fuel efficiency by up to 15%.
Unless your vehicle requires premium fuel, stick to regular unleaded. Using higher-octane fuel than recommended doesn't improve performance or efficiency—it just costs more at the pump.
Avoid rapid acceleration and hard braking. Gradual, smooth acceleration uses less fuel and improves overall vehicle efficiency. Anticipate stops ahead to brake gently.
Driving at a consistent speed, especially on highways, is more fuel-efficient than frequently changing speeds. Cruise control can help maintain steady velocity and save fuel.
Under-inflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure monthly and maintain the recommended PSI found in your vehicle's door jamb or manual.
Extra cargo increases fuel consumption. Remove items you don't need for your trip. Even removing roof racks or carriers when not in use can improve fuel efficiency.
Use GPS or route planning apps to find the shortest or fastest route. Avoiding traffic congestion and unnecessary detours saves fuel, time, and money.
Idling consumes fuel without moving you forward. Turn off your engine if you're stopped for more than a few minutes. Modern vehicles use less fuel restarting than idling does.
Keep up with scheduled maintenance including oil changes, air filter replacements, and engine tune-ups. A well-maintained engine runs more efficiently and uses less fuel.
Air conditioning significantly increases fuel consumption. Use it only when necessary. At lower speeds, opening windows may be more efficient than using the AC.
Sharing rides with coworkers or friends splits fuel costs among passengers. Carpooling reduces per-person fuel expenses and helps the environment.
Avoid rush hour traffic when possible. Stop-and-go driving significantly reduces fuel efficiency compared to steady-speed travel during off-peak hours.
