Which engine oil is more suitable for cars in winter?
1 Answers
Because the temperature is relatively low in winter, the low-temperature fluidity requirements for engine oil are higher. It is recommended to use 0W grade engine oil. Below are the relevant introductions: 1. The engine oil used in winter must meet three major characteristics: low viscosity, low pour point, and good anti-wear performance, so as to provide good protection for the engine. 2. The temperature in winter is relatively low, so the fluidity of engine oil in cold conditions is poor. Some engine oils may even solidify in environments below minus ten degrees Celsius. Therefore, the engine oil used in winter needs to have good low-temperature fluidity. 3. The number before the "W" in the engine oil grade represents the low-temperature fluidity of the engine oil. 4. 0W indicates a minimum operating temperature of -35°C; 5W can operate in environments with a minimum temperature of -30°C; while 10W can only be used in environments above -25°C, and so on. 5. Car owners can choose the engine oil with the required low-temperature fluidity according to the local minimum temperature. The lower the temperature, the better the low-temperature fluidity of the engine oil required.
