[DeZoey]

The oil light on a car indicates that the engine oil light is illuminated, which is generally used to monitor the working status of the engine oil. It lights up when an abnormality is detected. Below is a detailed explanation: 1. Definition of the oil light: The oil light is a type of vehicle light designed to ensure that engine oil is properly delivered to the engine. Only normal oil pressure can guarantee that the oil reaches all the surfaces of the engine components. 2. The role of engine oil: Both excessively high and low oil pressure can affect engine performance and even cause damage to engine parts. 3. Reasons for the oil light turning on: When the oil pressure sensor detects a fault in the oil pressure, it will illuminate the oil light. 4. Solution: When the oil light comes on, it is necessary to promptly identify the cause and resolve the issue. There can be various reasons for abnormal oil pressure, such as insufficient oil quantity leading to a drop in oil pressure, or the use of inappropriate oil viscosity for the engine.
