What are the signs of insufficient engine oil?

[KeeganMarie]

When the engine oil is insufficient, the car dashboard usually lights up an icon, the engine oil pressure warning light, to remind the owner of the insufficient oil. At this time, the owner should go to the nearby gas station or auto repair shop to replenish the oil as soon as possible to avoid further damage to the engine due to insufficient oil. The relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricating oil, English name: Engine-oil. The density is about 0.91×10³ (kg/m³), which can lubricate and reduce wear, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and absorb shock for the engine. It is known as the "blood" of the car. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricating oil, determining the basic properties of the lubricating oil. The additives can compensate for and improve the shortcomings of the base oil, giving it some new properties, and are an important part of the lubricating oil.
