5 Bad Driving Habits That Waste Fuel and Cost You More
Fuel efficiency is a priority for most drivers, especially with the rising costs of gasoline and the growing importance of reducing environmental impact. However, many people unknowingly waste fuel through their everyday driving habits. Small behaviors behind the wheel can add up to significant increases in fuel consumption. Recognizing and changing these bad habits can save money and reduce emissions.
One of the most common fuel-wasting habits is aggressive driving. Rapid acceleration, speeding, and sudden braking force the engine to work harder than necessary. Studies have shown that aggressive driving can lower fuel economy by up to 30 percent on highways and 40 percent in city traffic. A smoother driving style not only conserves fuel but also extends the life of the vehicle.
Another major culprit is idling for long periods. Many drivers leave their engines running while waiting, believing it consumes less fuel than restarting the car. In reality, idling for more than a minute wastes more fuel than shutting the engine off and restarting it. Modern engines are designed to restart efficiently, making unnecessary idling one of the easiest habits to correct.
Excessive speeding also reduces fuel efficiency. While driving faster may save time, it significantly increases aerodynamic drag, forcing the engine to burn more fuel. Most vehicles reach optimal fuel efficiency between 45 and 65 miles per hour. Beyond that range, fuel consumption rises sharply, often negating any time saved.
A less obvious but equally important habit is poor maintenance. Driving with underinflated tires, dirty air filters, or worn-out spark plugs makes the engine less efficient and increases fuel use. For example, properly inflated tires can improve gas mileage by as much as 3 percent. Regular maintenance ensures the car operates at peak efficiency.
Finally, carrying unnecessary weight or improper use of roof racks also hurts fuel economy. An overloaded trunk or a roof box increases resistance and forces the engine to burn more fuel. Reducing weight and removing unused racks can improve efficiency noticeably.
