Show answer & explanation
Correct answer: Parts of the engine may suffer increased wear..
Engine oil becomes inefficient over time; losing its viscosity and lubricating qualities; and therefore must be changed as required in accordance with the manufacturer's recommendations. Failure to do so may result in costly and extensive engine damage. The oil change is usually done when the vehicle is being serviced.
