What is one way to improve your vehicle's fuel efficiency?

Maintaining proper speeds is a critical factor in enhancing your vehicle's fuel efficiency. Vehicles are designed to operate optimally within a specific speed range, typically between 45 and 65 mph for most cars. When driving at these speeds, the engine functions efficiently, utilizing fuel at an optimal rate.

At higher speeds, aerodynamic drag increases, leading to greater fuel consumption as the engine works harder to maintain speed. Conversely, driving at excessively low speeds can also lead to increased fuel use as the vehicle may not be operating efficiently in terms of power and throttle usage. Thus, adhering to recommended speed limits and maintaining consistent speeds not only helps in conserving fuel but also contributes to safer driving practices by reducing sudden accelerations and decelerations.

Other options significantly impact efficiency. Driving with windows down can increase drag on the vehicle, reducing fuel economy. Excessive idling wastes fuel as the engine consumes gasoline without propelling the vehicle. Carrying heavy loads causes the engine to exert more energy to move the vehicle, leading to decreased mileage. Therefore, maintaining proper speeds stands out as an effective strategy to maximize fuel efficiency.
