Volkswagen's full synthetic oil can typically be changed every 10,000-12,000 kilometers or every six months. If the driving environment is dusty, the temperature is relatively low, or the car is frequently used for short trips, it is recommended to shorten the oil change interval to ensure smooth engine operation. Method for changing oil in cars: Use a jack to lift the Volkswagen car, locate and loosen the drain plug to drain the oil; unscrew the oil filter and place a container beneath it; replace with a new oil filter and add new oil. Meaning of oil grades: The 'W' stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The number after 'W' indicates the oil's high-temperature resistance; the larger the number, the better the oil's protective performance under high temperatures. Classification of engine oils: Conventional mineral oil, semi-synthetic oil, and full synthetic oil. Mineral oil is a commonly used lubricant on the market, derived from useful substances during petroleum refining. Semi-synthetic oil uses semi-synthetic base oil, a product purified from mineral oil through hydrocracking technology. Full synthetic oil is the highest-grade oil among engine oils.
