What should a driver do to ensure better fuel efficiency from their vehicle?

Regularly servicing the vehicle is essential for achieving better fuel efficiency. A well-maintained engine operates more smoothly and effectively, which directly impacts fuel consumption. Regular servicing includes checking and replacing air filters, ensuring that the engine is properly tuned, maintaining optimal tire pressure, and addressing any mechanical issues. When these aspects are attended to, the vehicle can operate efficiently, leading to reduced fuel usage and improved overall performance.

In contrast, filling the tank to maximum capacity does not significantly affect fuel efficiency—it primarily addresses storage limits and weight. Driving at higher speeds consistently tends to increase fuel consumption due to increased aerodynamic drag and engine strain. Similarly, frequent use of air conditioning can burden the engine, making it work harder and often resulting in higher fuel consumption. Thus, regular servicing stands out as the most effective choice for enhancing fuel efficiency.
