What type of maintenance can improve fuel economy?

• A. Regular oil changes, air filter replacements, and proper tire maintenance
• B. Engine repair and bodywork
• C. Adding fuel additives regularly
• D. Increasing the tire pressure excessively

Answer: (A)

Regular oil changes, air filter replacements, and proper tire maintenance are fundamental aspects of vehicle maintenance that can significantly improve fuel economy. Performing regular oil changes ensures that the engine runs smoothly and efficiently. Clean oil reduces friction between moving parts, which can lead to better fuel combustion and improved overall performance. Replacing the air filter is also crucial; a clean air filter allows the engine to breathe more easily, ensuring that the right amount of air is mixed with fuel for optimal combustion. A clogged air filter can reduce engine efficiency and lead to increased fuel consumption. Proper tire maintenance, which includes maintaining the correct tire pressure and ensuring tires are in good condition, helps reduce rolling resistance. Under-inflated tires can cause the engine to work harder than necessary, leading to decreased fuel efficiency. Therefore, regular attention to these maintenance tasks is essential for optimizing fuel economy.
