What are the consequences of operating an engine with low oil levels?

Operating an engine with low oil levels can lead to catastrophic engine failure due to overheating, which is the correct consequence in this scenario. Oil plays a critical role in lubricating engine components, reducing friction, and dissipating heat. When oil levels are low, there is insufficient lubrication, leading to increased friction between moving parts. This friction generates excess heat, which can escalate quickly within the engine.

As temperatures rise, the risk of overheating becomes significant. Over time, this can cause critical components, such as bearings and pistons, to wear out prematurely or fail completely. Additionally, overheating can lead to warping of engine parts, failure of gaskets, and even complete engine seizure, which would ultimately result in catastrophic engine failure. Therefore, maintaining proper oil levels is essential for optimal engine operation and longevity.
