What happens when engine oil dries up?

[VonFrank]

When engine oil dries up, it loses its lubricating function, causing engine components to rub against each other and become damaged. Additionally, without the cooling effect, phenomena such as burning crankshafts and bearing shells may occur during high-speed engine operation. The primary function of engine oil is to provide appropriate lubrication for the engine's pistons, bearings, and other components. Car owners should avoid frequent sudden acceleration and prolonged high-speed driving during regular vehicle use. High-speed engine operation can easily break the lubricating oil film, leading to poor lubrication and dry friction in rotating parts. When this becomes a regular practice, it can cause abnormal engine wear and result in oil burning.
