Mention the oil, I believe that the owners know its role. As the name suggests, this substance is actually mainly the lubricating oil of the car engine, which not only has the role of lubrication, rust prevention, cushioning, etc., but also can achieve cooling and cooling. It is of great significance for the operation of various components of the engine inside the car. Because of this, in cars, the engine is often called the heart of the car, and the oil is called the blood of the car.
But on the blood problem of the car, there is now a very difficult problem to understand. That is, the vehicles driving abroad, often 20,000-30,000 kilometers will replace the oil once, but if it is placed in the domestic driving, many 4S shops will require the owner to change the oil once when driving 5,000 kilometers, what is the reason that there will be such a huge difference between domestic and foreign countries?
In fact, the answer to this question is mainly influenced by many factors. In addition to the differences in the oil itself, there are certain differences in the driving environment, automobile sales environment, etc. at home and abroad. In such a situation, the change of oil for different mileages naturally seems very normal.
First of all, the difference between the oil itself, what many people don't know is that the oil added by many domestic car owners driving vehicles is mineral oil, and this oil is completely normal for 5,000 kilometers. However, the oil added abroad is often a fully synthetic oil, which can be replaced once for 20,000-30,000 kilometers.
As far as the quality of motor oil is concerned, there is also a certain difference between domestic and foreign countries. Like the domestic automotive oil more common standard is API, but foreign automotive oil standards are generally AECA. Especially in Europe, for example, there are almost no domestic APIs. According to relevant information, the quality of AECA's oil is obviously better. Because of this, it is normal for foreign cars to change oil for 20,000-30,000 kilometers.
Secondly, there is a big difference between the domestic car driving environment and foreign countries, for domestic car owners, driving on the road to encounter traffic jams I believe everyone has encountered. Not to mention that large cities such as Beijing, Shanghai, Guangzhou, and Shenzhen are prone to traffic jams, even in third- and fourth-tier cities, they are often prone to traffic jams. In the case of engine work, the speed can not be improved, which eventually leads to a reduction in the life of the engine oil!
In addition to some international metropolises abroad, it is basically difficult to have traffic jams in other regions. Even in a big car country like the United States, only a few big cities get stuck in traffic. In other words, when the foreign automobile engine is doing work, the working conditions are better, and the engine is in a good working condition for a long time, which also greatly increases the oil life.
This is actually easier to understand through a simple comparison of data. Assuming that the average speed of a car in China is 25 kilometers per hour, after spending 200 hours, the car mileage reaches 5,000 kilometers. In the same time, the average speed of foreign cars can reach about 60km/h, and the journey of foreign cars exceeds 5,000 kilometers.
Therefore, in a sense, in fact, the mileage of oil replacement at home and abroad is different, mainly because the engine has a different mileage in the same working time.
In fact, in addition to the quality of the oil and the different driving environments at home and abroad, the automobile sales environment will also become one of the main reasons affecting the oil replacement. For this point, many car owners have expressed their deep understanding. After purchasing the desired vehicle, many sales staff will remind the owner that after the mileage of the car reaches 5,000 kilometers, it is necessary to remember to change the oil at the 4S store.
Many people believe that the reason why 4S stores require car owners to change oil so "frequently" is actually to be able to get more benefits by shortening the use cycle of oil. More importantly, in the process of changing the oil, the relevant staff will also sell more services, after all, every time there is an opportunity for exchange, the opportunity to launch services will be greater.
But in fact, although this is one of the reasons for frequent oil changes, it is by no means the main reason. After all, whether the oil needs to be changed, the ultimate initiative is still in the hands of the owner. What's more, there are more and more car repair shops nowadays, even if you don't go to the 4S shop to change the oil, you can also go to other places to change the oil. So in this regard, it is still a little reluctant.
Of course, as far as the actual use of engine oil is concerned, the best way is to decide according to the actual environment you are facing. If in the process of using the car, the driving environment is rarely congested, and you have never had the habit of changing the original geothermal car, then in the case of using AECA standard oil, even if the mileage of oil replacement is extended, there is not much of a problem.
If the car environment is not very good, following the advice of the 4S shop will not be too much of a problem. Especially for novice owners, strictly in accordance with the car maintenance manual, there will be no big problem!
