How often does the car need maintenance? What must be done in maintenance?

According to the environment and vehicle technology, the longest maintenance in China is 8000- 10000, most of which is 5000, which can be shortened appropriately according to the use environment.

The maintenance process of diesel vehicles is different and the mileage is the same.

There are certain skills in car maintenance. When driving, get into the habit of checking the oil meter every morning before driving and replenish the oil in time. Check whether there is less water in the water tank and check the brake oil. Generally, there will be no problem. Please also note:

1: Do not warm up the engine at idle speed. At present, the EFI engine has a temperature compensation control system, which can meet the normal running of the vehicle in the cold state. If the EFI engine is warmed up for a long time, it will only increase fuel consumption invisibly. After the car is started, the original floor heater should be used, and it should be started after the water temperature reaches the starting temperature. When driving, you should choose a good road surface, keep driving at a medium speed, keep the throttle low, and try to avoid sudden acceleration and sudden braking.

Don't let the engine run at high speed when driving.

3. Avoid engine overload. Running at full load is easy to damage parts, so it cannot exceed 75%-80% of the rated load. Never help others tow a car, it will do harm to others.

4. Always check whether the engine oil, coolant, storage battery and electrolyte are sufficient, and replenish them in time if found missing.

Generally speaking, the oil and three cores (gasoline filter, oil filter and air filter) should be changed every 5,000 kilometers. This is very important and can prolong the service life of the engine.

6: The tire should be changed back and forth every 20,000 kilometers (right front turns to left rear wheel, left front turns to right rear wheel).
