What maintenance does Bluebird do for 30,000 kilometers?

If you don't pay attention to maintenance, the performance of the car will be greatly affected after driving 30 thousand kilometers.

First, replace the air filter.

After 30,000 kilometers, the air filter will be covered with a lot of dust and engine oil, and the performance of the air filter will be greatly affected when driving 30,000 kilometers, so it is best to replace it to ensure its working performance. Therefore, most car maintenance manuals will clearly stipulate that the air filter must be replaced after the car travels 30,000 kilometers.

Second, replace the oil filter.

This principle is very similar to the air filter. When a car travels 30 thousand kilometers, the oil filter will produce a lot of impurities, which greatly reduces the lubrication function and heat dissipation function. Therefore, regular replacement is very necessary.

Third, oil pollution cleaning.

Generally, it includes combustion chamber oil circuit cleaning and engine internal cleaning. Oil cleaning is mainly to clean carbon deposit, which is the deposit produced after incomplete combustion of the blowby mixture of lubricating oil and gasoline. Of course, this is not necessary, and it should be analyzed according to the actual situation of the car. If the car was treated during the last maintenance, it can be ignored this time.
