What are the hazards of insufficient engine oil in a car?

[DeNicole]

The engine of a car is like the heart of a person, and the engine oil is like the blood flowing in the heart. If the engine lacks oil, the oil light will first come on. In severe cases, the vehicle may start to shake. You should immediately pull over and turn off the engine; otherwise, there is a risk of the engine being ruined, and professional assistance should be sought. When the engine is low on oil, the following symptoms may occur: 1. Poor lubrication in the splash lubrication areas inside the engine. 2. When the oil level drops to the point where oil pressure is too low, it can cause poor lubrication on the friction surfaces of the engine, leading to abnormal shaking, reduced power, and in severe cases, engine "bearing seizure." 3. When the oil pressure is too low due to insufficient oil, it can also cause the engine's variable timing solenoid valve to malfunction, resulting in inaccurate control of the engine's intake and exhaust valves, abnormal operation, reduced power, increased fuel consumption, and other symptoms.
