Landlord, it's too complicated. It doesn't mean anything to you. You can simply write down the following principles: First, the oil change cycle is closely related to the environment in your car. Volkswagen suggests changing it once every 7500 years or half a year, but if your car environment is not good, such as frequent traffic jams, frequent short-distance driving, frequent acceleration and deceleration, and heavy dust ... Then, you can shorten the oil change interval appropriately, such as 5000KM or 3 months. On the contrary, it can be extended appropriately, such as 1WKM or one year. Second, total synthesis mainly provides better cleaning and protection effects. But for daily use, the difference is not too big. The total synthesis is 1W5KM or only one year, but the effect is not as good as that of 5000KM, and it is changed three times a year.
