What does oilchange mean when it appears on a car?

oil-change means oil change. The "oil-change" indicator usually appears on the car's dashboard. When the OIL-CHANGE light comes on, it means that the engine oil and lubricating oil should be replaced as soon as possible, which is a maintenance reminder for the vehicle. This indicator light is specifically used to record the mileage and time the car has traveled since the last maintenance. When the mileage and time reach the set value, this indicator light will turn on. The elimination method is as follows: When the power is off, that is, the screen is black and the car is completely powered off, press and hold the SEL button with your left index finger for 5 seconds without releasing it. Then, start the power with your right hand to light up the dashboard, and continue holding the SEL button with your left index finger for another 3 seconds. The OIL-CHANGE indicator light will then disappear. If the oil warning light comes on while driving, it indicates that the oil level is insufficient, and the car should not continue to be driven. Engine oil plays a significant role in lubricating the engine's operation. Insufficient oil will lead to inadequate engine lubrication, increasing engine wear. Additionally, the engine's cooling function may not work properly, causing the engine to overheat. Over time, the engine may even be damaged, which poses a significant danger to the occupants of the car. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the oil's kinematic viscosity at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. When selecting engine oil, the following points should be noted: Choose engine oil based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oil should be preferred. Multi-grade oil is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, it may appear darker prematurely and have lower oil pressure compared to regular oil, both of which are normal.
