What are the three maintenances for a car?

[KylieRose]

Car three maintenances refer to the first maintenance, the second maintenance, and the third maintenance. Car maintenance cycle: The car maintenance cycle is set when the vehicle leaves the factory, so the "small wrench" symbol will appear every certain mileage to remind the driver to perform maintenance in time. Usually, the maintenance cycle for a car is every 5,000-8,000 kilometers, and the factory-set cycle is generally longer than 8,000 kilometers. Regular maintenance items: Oil maintenance, oil is also called lubricant, which can reduce engine wear and also has the effects of cooling and lubrication for the engine. There are three types of oil: full synthetic oil: needs to be replaced every 10,000-12,000 kilometers. If the car is not driven frequently, the oil may emulsify and lose its effectiveness, so it needs to be replaced after about a year. Semi-synthetic oil: needs to be replaced every 8,000-10,000 kilometers. Mineral oil: needs to be replaced every 5,000 kilometers.
