What happens when a car runs low on engine oil?

[JoelMarie]

If a car's engine is low on oil, it will increase engine wear and lead to louder engine noise and reduced operational smoothness. If the engine is low on oil, it must be refilled immediately. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, granting it new characteristics. Additives are a crucial part of the lubricant.
