Replacing a clogged air filter can improve fuel efficiency by what percentage?

• A. 5 percent
• B. 10 percent
• C. 15 percent
• D. 20 percent

Answer: (B)

Replacing a clogged air filter can significantly enhance fuel efficiency, primarily because a clean air filter allows for better air flow into the engine. An optimal air-to-fuel mixture is crucial for the combustion process to work efficiently. When the air filter is clogged, it restricts airflow, leading to a richer fuel mixture that can waste fuel and reduce performance. Research and automotive expert recommendations suggest that replacing a clogged air filter can improve fuel efficiency by approximately 10 percent. This percentage reflects the balance achieved when airflow is restored to optimal levels, allowing the engine to operate more effectively. Hence, the correct choice highlights the tangible benefits of maintaining your vehicle, demonstrating how even small maintenance tasks can lead to measurable improvements in efficiency.
