Final answer:

Engine oil aids engine efficiency by reducing friction between parts through the use of thin oil layers.


Explanation:

Engine oil helps the engine operate efficiently by d. reducing friction between engine parts. Thin layers of oil between moving parts reduce friction significantly compared to direct contact, allowing smoother operation. Viscosity plays a crucial role as temperature changes affect the effectiveness of the oil in lubricating the engine.
