Oil check operation can be affected by which two factors?

The correct pairing of factors that can affect oil check operation is leaks and temperature.

Leaks can compromise the integrity of the oil system by allowing oil to escape, which can lead to insufficient lubrication of moving parts. This can cause increased wear, reduced efficiency, and ultimately system failure. Therefore, monitoring for leaks is crucial to maintain the proper functionality of the lubrication system.

Temperature plays a critical role as well because it affects the viscosity of the oil. Higher temperatures can thin the oil, causing it to flow too easily and lose its lubricating properties, while lower temperatures can thicken the oil, making it less effective in circulating through the system. Maintaining an appropriate temperature range is essential for optimal oil performance.

In contrast, while humidity, noise, and vibration can have their own impacts on system operation, they are not directly influential on oil check operation in the same significant manner as leaks and temperature are. Hence, the focus on leaks and temperature provides a clear understanding of the primary factors influencing oil checks.
