What happens when a car has low engine oil?

[Ryan]

Insufficient engine oil can cause harm to the car. Hazards: When the oil level drops to the point where oil pressure is too low, it can lead to inadequate lubrication of the engine's friction surfaces. This may result in abnormal vibrations, reduced power output, and in severe cases, can cause engine bearing seizure or even engine stalling, posing a danger while driving. Function of engine oil: Engine oil serves as a lubricant. During engine operation, the crankshaft connects to the connecting rod through components commonly known as "bearings," and the crankshaft itself is mounted on the engine block also via bearings. Additionally, the piston rings and cylinder walls experience friction. Without oil lubrication, these components would experience dry friction, significantly increasing the friction coefficient and causing severe wear to engine parts.
