Which statement is true regarding benefits of regular vehicle maintenance?

Regular oil changes are essential for maintaining engine health because oil serves as a lubricant that minimizes friction between moving parts, which in turn reduces engine wear. Over time, oil can become contaminated and lose its effectiveness, making routine changes crucial for optimal engine performance.

Replacing the air filter also plays a significant role in maintaining engine health. A clean air filter allows for proper airflow to the engine, which is vital for efficient combustion. If the air filter becomes clogged, it restricts airflow, leading to a rich fuel mixture that can cause incomplete combustion, reduced power, and increased wear on engine components.

Choosing the statement regarding both regular oil changes and air filter replacements accurately reflects the comprehensive approach needed for vehicle maintenance to ensure long-term engine durability and performance.
