Every owner knows that after taking the new car home, it will be maintained every once in a while, and in a series of maintenance projects, the oil change is the most basic link. Engine oil is a relatively fast consumption product for many car owners, and the vast majority of car owners will replace the car oil every once in a while as instructed by the 4S shop.
Some car owners who have gone abroad have found an interesting thing, many European and American owners usually will change the oil once after the car travels 20,000 to 30,000 kilometers, but when the domestic car owner buys a car, the salesman of the car dealer will usually remind the owner in advance that the car is best to change the oil every 5,000 to 6,000 kilometers, why is this? Are car dealers just alarmist and want to make money this way?
The role of automotive oil
If the engine is the heart of the car, then the oil is the blood of the car. Many car owners only know that the oil should be changed during maintenance, but they do not know why the oil should be replaced. In fact, the biggest role of the oil is that it can effectively protect the engine from damage, and can play a role in lubricating and reducing wear, assisting cooling and cooling, sealing and leak-proof, rust-proof and corrosion-proof. In addition, the oil ensures that the various components in the engine run smoothly and efficiently. The oil is a consumable, itself has a certain validity period, so it needs to be replaced frequently to ensure that the oil works properly.
The reason for the frequent oil change in china
Of course, we can't completely deny that there are some car dealers who want to make profits from car owners by shortening the oil change cycle, but this is not the main reason. What really affects the shortening of the oil replacement cycle of car owners is the difference in the main components of different oils at home and abroad.
For the domestic automobile market, the most important type of oil is mineral oil, which is exposed to the air for a long time during use, so it is very easy to oxidize, thus losing its original role. Therefore, car dealers will generally make a reminder in advance when the owner buys a new car, so that the owner can change the oil every 5,000 kilometers to 6,000 kilometers. Relatively speaking, the most commonly used oil in foreign countries is basically a fully synthetic oil, which is more suitable for models with pressurization technology, and the replacement cycle is longer, and frequent replacement will cause oil waste.
In addition, the traffic situation at home is much more complicated than abroad, and the increase in the number of cars has made many cities more congested, so the engine runs longer. Compared with the sparsely populated foreign countries and basically no traffic jams, the loss of the engine has increased, and the oil is naturally not so durable.
summary:
When choosing oil, car owners should pay attention to the choice of oil in addition to paying attention to the purchase of genuine products in those big auto parts cities or 4S stores. If the owner's usual demand for the car is not so high, the maintenance cycle is relatively fixed and the performance requirements are not high, it is obvious that the economical mineral oil is more suitable for the owner. On the contrary, if the owner uses the car more frequently and does not want to frequently run the 4S shop for maintenance, the fully synthetic engine oil is obviously more suitable. In addition, some more powerful models should also use fully synthetic motor oil.
