Besides lubricating parts that rub against one another, what function does engine oil perform?

Correct answer

Contribute to cooling engine components.

It helps remove heat from engine components and contributes to cooling. It can also provide cleaning, protection and sealing. Maintain the correct level and use the manufacturer-specified oil; it does not replace repairing a coolant-system leak or tension engine belts.
