What Happens When a Car is Low on Engine Oil?

[StSophie]

The engine of a car is like the heart of a human being, and the engine oil is like the blood flowing within that heart. When the engine is low on oil, the oil warning light will first illuminate, and the following symptoms may also 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 lead to inadequate lubrication on the engine's friction surfaces, resulting in abnormal vibrations, reduced power, and in severe cases, may even cause "bearing seizure" in the engine. 3. When the oil level drops to the point where oil pressure is too low, it can also cause the engine's variable timing solenoid valve to malfunction, leading to an inability to precisely control the engine's intake and exhaust valves. This can result in abnormal operation, reduced power, increased fuel consumption, and other symptoms.
