How can low oil levels affect engine temperature?

Low oil levels can lead to increased engine temperature due to the essential role that oil plays in engine lubrication, cooling, and heat dissipation. Engine oil minimizes friction between moving parts, which produces heat as a byproduct. When oil levels are low, the ability of the oil to properly lubricate these components diminishes, resulting in increased friction and, consequently, higher temperatures.

Additionally, oil also serves to absorb some heat from the engine parts and carry it away to be dissipated through the engine's cooling system. With insufficient oil, this cooling mechanism is compromised, leading to a rise in engine temperature. Therefore, maintaining adequate oil levels is critical for preventing overheating and ensuring optimal engine performance.
