The oil is replaced once for 10,000 kilometers, the oil is replaced once for half-10,000 kilometers, and the mineral oil is replaced once at 5,000 kilometers.
1. If the mileage is less than 10,000 kilometers, the oil should be replaced according to the time cycle. The specific method is that when the entire synthetic oil is used for one year and does not reach 10,000 kilometers, the oil should be replaced. Synthetic oil has been used for half a year, but it has not yet reached 8,000 km, so the oil should be replaced. The time period and mileage are combined and replaced according to who arrives first. My main concern is that oil will spoil after too long.
2, the maintenance cycle of the car is usually consistent with the oil change cycle, which means that the maintenance of the car is actually coordinated according to the oil change cycle. Relatively speaking, there are very few cases of self-examination. In addition, we are not professional automotive technicians, so we have different opinions on when we need to change the oil.
3, the car is a very precise parts assembly, not only the engine, but also many parts have their own service life. We pay more attention to some maintenance details when driving, which also has a great impact on the service life of the vehicle. In particular, engine oil, transmission oil, etc. are slowly affecting the service life of cars, and the same is true for brake oil.
