Oil is the "blood" of a car, which can be used to lubricate, clean, cool, seal and rust the engine. When the engine is running, the internal working condition is very serious and harsh, in high temperature, high speed and no changes in the rules, the mechanical friction of metal debris from the air, dust, intrusive combustion of acid, some of the exhaust gas into the crankcase, will cause the oil deterioration, it will bring a lot of damage to the engine. So after a certain mileage of the car, the oil must be replaced. But the correct grasp of the oil exchange cycle is very important to prolong the service life of the engine and save the oil. If the oil changing cycle is too long, the oil will be aging and dirty, and the additives will also evaporate and dissipate. The protection of the engine will weaken. If the oil changing cycle is too short, it will cause unnecessary waste. Therefore, the oil must be replaced in a normal and reasonable period.

There are many factors affecting the oil exchange cycle, mainly depending on the environment, conditions and temperature of the vehicle, as well as the quality of the oil and the precision of the engine. It is best to grasp the oil exchange cycle according to the following factors:

(1) under normal circumstances, oil exchange should be carried out on the basis of the oil exchange period stipulated in the manual of the automobile manufacturer. In general, most manufacturers will require cars to change their oil once 5000km or 7500km. However, due to the fact that the actual environment and conditions are different, they will not be able to go all the way. The time of oil exchange and the length of the kilometer should be adjusted according to the specific circumstances of the use of the car.

(2) if driving frequently in urban area, because of low speed, short distance and frequent start and stop, its oil mileage is relatively shorter than that in the suburbs. This is because the condensate and unburned matter of the engine are easy to enter the engine oil, and the working temperature of the engine is low, so the condensate in the crankcase can not be evaporated very quickly, so that the oil will deteriorate and deteriorate too early.

(3) in the hot summer and cold winter months, the oil aging rate of Baotou Bei Ben heavy truck parts is obviously faster, so its oil mileage will be shortened.

(4) if driving frequently in bad traffic and dusty areas, due to the large engine load and bad environment, the oil changing cycle will be relatively short.

(5) if the Baotou beiben heavy truck engine parts working in heavy load conditions, especially often overload or full load use vehicles, because Baotou beiben heavy truck engine parts often run at high speed, fast aging oil dirty, too fast, so it must shorten change period.

6. If an old car is compared with a new car, because the engine precision of the old car is greatly reduced, the exhaust gas will easily enter the crankcase and accelerate the aging and deterioration of the oil, so the oil changing cycle will be relatively short. Even if the same vehicle is on the same road condition, the change of oil mileage is also different in different use stages.

(7) if the vehicle is often used under the condition of the road and environment, such as running on the highway, the engine works smoothly, the running is uniform and the wear is lighter, its oil changing cycle can be extended appropriately.

(8) if the oil of high quality grade is used, the oil changing cycle can be greatly extended. Therefore, the oil quality level is different and the oil exchange cycle is different.

(9) if the mileage of the car is very few in peacetime, the oil change mileage stipulated by the manufacturer is not available for half a year, then 1-2 oil should be replaced every year. Because the oil is in contact with the air for a long time, it will naturally aging, and the additives in the oil will volatilize and make the oil fail.
