How many kilometers does the third car maintenance require?

[DeJaxon]

Generally speaking, the third maintenance is required at around 20,000-25,000 kilometers. The replacement cycle for mineral oil is about 5,000 kilometers; for synthetic oil, it's about 10,000 kilometers. Oil filter. To ensure the cleanliness of the oil circuit, the engine is equipped with an oil filter in the lubrication system, designed to prevent impurities from mixing into the oil, causing oxidation and producing sludge that can block the oil circuit. The replacement cycle for the oil filter is the same as that for the oil, and it must be replaced simultaneously with the oil. Air filter. The air filter's function is to block dust and particles that the engine inhales during the intake process. If the filter is not cleaned for a long time, it can lead to the engine inhaling dust, causing abnormal wear on the cylinder walls. It is best to clean the air filter every 5,000 kilometers by blowing it clean with an air gun, and replace it every 10,000 kilometers. Fuel filter. Although gasoline quality is gradually improving, it is still inevitable that some impurities and water will mix in. Therefore, gasoline must be filtered before entering the fuel pump to ensure smooth fuel flow. Since the fuel filter is for one-time use, it should be replaced every 10,000 kilometers.
