Do you have to replace the car air filter for maintenance?

The maintenance manual is more conducive to operation and maintenance.

1. Oil: Changing oil is the most common item in maintenance. Engine oil plays the role of lubrication, cooling, shock absorption and reducing engine wear. Oil has a long life and should be replaced regularly. Different types of oil have different replacement cycles. At present, there are three kinds of engine oils: all-synthetic engine oil, semi-synthetic engine oil and mineral engine oils.

2. There are relatively good high and low temperature models in synthetic engine oil, and the price is the highest among the three. The replacement cycle is generally 10000- 12000 km. The replacement cycle of semi-synthetic engine oil is 8000- 10000 km. Generally, the replacement cycle of mineral engine oil is 5000 kilometers.

3. Three filters: Three filters refer to three filters for engine oil, three filters for air and three filters for air conditioning. The function of the oil filter is to remove all kinds of impurities in the oil and ensure the normal operation of the lubrication system, so the oil filter should be replaced with the oil when changing the oil. The air filter element is used to filter air and ensure the cleanliness of air intake. The replacement period is 20,000 kilometers or 2 years. The air conditioning filter element is to prevent dust and odor from entering the car, and the replacement cycle is 20,000 kilometers or 2 years.

4. Spark plug: The function of spark plug is to ignite the combustible mixture in the cylinder. Once the working time is too long, it will make the engine run irregularly, produce jitter, and even cause cylinder shortage and misfire. At the same time, it will make the engine consume more fuel, so the role of spark plug is very important.
