Change the engine oil once every 5000 kilometers, why does the 4S shop say so?

A relevant person in charge of the after-sales service department of an automobile manufacturer told reporters that the maintenance mileage or cycle recommended by the manufacturer is formulated according to the wear law of parts, and the accurate cycle calculated according to the characteristics of specific vehicles is very scientific. "Because after a period of use, the consumption and deterioration of the oil will inevitably lead to a decrease in its lubrication function, and the wear rate on the engine will increase, so that the technical condition of the vehicle will deteriorate. At worst, it will affect the working efficiency of the machine and reduce the service life of the vehicle, and at worst, it will cause the engine piston to dry wear due to the lack of oil, resulting in major failures of the vehicle.

The person in charge believes that the reason why the maintenance cycle of different car series and brands is very different is caused by the difference in the specific technical conditions of different vehicles.

<> 4S shop recommends that 5000 kilometers of maintenance is not suitable for this need to be separated, many model manufacturers require the use of mineral oil is 5000 kilometers of maintenance once, 4S shop if in accordance with the manufacturer's requirements is no problem, the maintenance manual is written very clearly. If the maintenance manual requires the use of synthetic engine oil for 10,000 kilometers of maintenance, and the 4S shop also requires 5,000 kilometers of maintenance, it is a bit excessive, so whether it is suitable depends on the requirements of the maintenance manual, and it is certainly unreasonable not to follow the manufacturer's requirements.

I myself am Mazda CX4, 4S send 10 barrels of the so-called original 0-20 fully synthetic oil, since it is fully synthetic, I asked him why 5000 kilometers to change, we don't mention whether the oil he sent is fully synthetic, because Mazda and FAW Group do not produce engine oil, this is very easy to understand, think about it yourself, 4S is to make money, you go to a working hour to spend material costs or something to hundreds of dollars, send you 10 barrels of so-called original fully synthetic engine oil its purpose is not to say, China is too much. Therefore, the number of kilometers and the time to change the oil will be early. The number of kilometers and the time to change the oil abroad will be twice as long as that in China.

Because after driving so many kilometers, the vehicle needs to rest, and changing the oil once can better range the vehicle and also help the maintenance of the vehicle.

The 4S shop is informed to the customer according to the advice of the automobile manufacturer, and they also tell the customer according to the manufacturer's guidance mileage.

The 4S shop said that the oil needs to be changed at 5000 km, but it can still be used when it is used beyond 5000 km, but it is not recommended.

Because in this way, the 4S store can have a better profit and make a lot of profit from it, because the car owner will spend a lot of money on maintenance.

The main thing is to maintain this engine, and such a long kilometer can continue to change the oil, but also to be able to use it better.

Because this is more beneficial to the car, it will not make the car consume too quickly.

Because this will be better for the car, and it can also bring greater profits to the 4S shop.

It is more reasonable to change the engine oil once in 5000 kilometers.

There are two types of motor oils: fully synthetic, semi-synthetic, and mineral.

The oil change interval of fully synthetic engine oil is basically about 12,000 to 15,000 kilometers, and if it is combined with a long-term machine filter, it can be completely changed once more than 20,000 kilometers.

Semi-synthetic engine oil, its lubrication effect is slightly better than mineral engine oil, basically can reach about 8000 kilometers.

Mineral engine oil, in most car maintenance, as long as it is not a high-grade model, such as a 100,000-level daily transportation car, most of them use mineral engine oil.

Because after 5,000 kilometers of driving, the lubrication effect of the oil will be greatly reduced, so you have to change the oil once.

Because the driving time is too long, the viscosity of the oil will become smaller, and the resistance of the lubricating oil will become larger, which is not conducive to the long-term driving of the car, so it must be replaced.

Not big, to be precise, there is no impact at all, and now most domestic car manufacturers are generally set at about 5,000 kilometers for the first insurance kilometers of their vehicles. However, in some European and American countries, many cars have a first warranty of 10,000 kilometers, or even longer. At the beginning, the reason why these foreign automobile companies chose to set 5,000 kilometers was that due to poor domestic road conditions, large dust and other reasons, they chose to set the first guarantee of the vehicle at 5,000 kilometers.

But that was decades ago, and it's still used today.

There are two main functions of engine oil, the first is to lubricate the mechanical parts, and the second is to cool down the engine so as not to cause damage to the mechanical parts due to excessive engine temperature. Of course, the oil is not always effective, and the effect of the oil will slowly decrease over time.

The maintenance of the vehicle also depends on the type of engine oil used, ordinary engine oil: Qingchan 5000 Gongshan Kuanli, semi-synthetic engine oil: 7500 km, fully synthetic:

10000 km. In fact, the engine oil we use now usually reaches an optimal run-in state at 5000 kilometers, and it is indeed a pity to change the engine oil at this time. Nowadays, the common practice of many car owners is to carry out maintenance for a year or 10,000 kilometers.

Of course, there are some times when some unscrupulous 4S shops or car companies accelerate the maintenance cycle of your car in order to earn more profits. For 4S shops, the profit from selling vehicles is not much, mainly to provide follow-up maintenance services for these car owners. In the author's hometown, there was only one 4S store of a certain brand, which was completely monopolized, and the attitude of the sales staff was very poor, but the attitude of the after-sales service staff was obviously good with the sales staff, and after we opened another one.

The after-sales service staff is completely butler service, not only to send you to the car, but also to watch your car leave. At the same time, you can also think that the money earned by after-sales service is indeed the bulk of the 4S store.

Of course, if you are a car lover, it is no problem to maintain your car according to the maintenance interval on the vehicle maintenance manual, but a moderate extension will certainly not cause damage to the vehicle.

Not too. Because this difference is not much, in fact, 5000 kilometers is only a conservative number, in fact, this data is more than 5000 kilometers of Yuanqing Li Yuan.

It's not a big problem, because it's only 200 kilometers over, not a lot.

Not a big problem. Because more than a few hundred kilometers are allowed, I don't think it's a big problem.

It has a lot to do with the road conditions abroad, and the cars used abroad travel 3 to 4 times as far as us every day! And because gasoline abroad is very cheap, they travel very long miles a day in sparsely populated places with mineral oil. No additives or minimal content.

It only meets the needs of low-end lubrication, and is rarely used in cars today, and can only meet the use of small displacement and small and medium displacement without turbocharged engines, 5000 kilometers or 3 to 6 months to replace.

<> is not to say that you are in the pit, when to change the engine oil, I believe you should also know it, even if you use a fully synthetic engine oil, it is recommended that it is best not to change it for more than a year. Especially when the car is often used in some harsh environments. How many kilometers does your car change the engine oil, there are many sayings on the Internet, and now the more mainstream is to change the engine oil according to the engine, for example, the fully synthetic engine oil is said to be changed once every 10,000 kilometers, which is reasonable, but the owner who does not use the full synthetic engine oil only refers to the maintenance manual.

Oil is always consumed, and if your driving environment is in the national highway long-distance commuting conditions, then although the mileage is more, but the engine always works in good heat dissipation conditions, then the oil deterioration is smaller, and the maintenance mileage can be appropriately extended, because they feel that China's road conditions and air quality are relatively poor, and at the same time frequent traffic jams, and frequent traffic jams will cause the vehicle to stop and open, which will inevitably lead to a large amount of oil in the engine, and dust can not avoid entering the engine.

3 months or half a year, mileage of 5000 kilometers, it must be replaced, of course, this is theoretical data, in fact, the attenuation cycle of the oil is relatively loose, said to be 5000 kilometers, but to 6000, or even 7000 can, but can not exceed too much. As a result, the lubrication effect of the engine oil becomes poor, and the oil sludge will be produced to adhere to the inside of the engine, which will lead to the blockage of the oil passage in serious cases, and the engine will have the possibility of pulling the cylinder and bursting tiles, which will directly lead to the scrapping of the engine and the inability to repair!

Because after more than 10,000 kilometers, the lubricating performance of the oil will be greatly reduced, so there is this requirement.

This is because if you do not change the engine oil for a long time, it is easy to damage the engine and affect the service life of the car.

Engine oil plays a vital role in the proper operation of the engine, such as lubrication, cooling, sealing, etc. High-quality engine oil can extend the life of the engine and keep the engine working in a good environment at all times. The oil itself will gradually weaken with the work, the oil molecules are very prone to some physical changes at high temperatures, and the engine will lose the protection it deserves, and the better filters on the market can generally be changed for 1w kilometers, so even if your oil is changed for 15,000 kilometers, you must go to the store to change the filter at 1w kilometers, and wait until another 5,000 kilometers to change the oil.

Therefore, it is recommended that car owners choose oil filters when choosing products with close service life to reduce trouble.

It depends on the type of oil to be used in the vehicle.

Generally, there are 3 types of engine oils, fully synthetic, semi-synthetic, and mineral engine oils.

Generally, fully synthetic engine oil is changed every 10,000 km or 1 year.

Generally, semi-synthetic engine oil is changed every 7500 km or 7-8 months.

The general mineral oil is changed every 5000 km or 6 months.

<>< 4S shop said 5000 kilometers to change the oil.

When it comes to car maintenance, then the first reaction of many car owners is the replacement of the engine oil, the 4S shop said that the oil was changed once in 5000km, and the car repairer told the truth, and the owner said that he was deceived.

The first thing we need to know is that there are three main types of engine oil, mineral oil, semi-synthetic oil and fully synthetic oil. Mineral engine oil is the worst lubrication degree in the entire oil system, and it is also the fastest deterioration, so the general car said that the oil is changed once every 5000km, which refers to the oil of mine and land ships.

Of course, the mineral oil needs to be replaced for 5000km, otherwise the use effect will become very poor.

The second type, semi-synthetic engine oil, semi-synthetic engine oil compared with mineral engine oil, the replacement time cycle is longer, and the use time cycle is also longer, so the experienced master will recommend that you replace the semi-synthetic engine oil at about 8000km, otherwise 5000km to replace, then it will waste a lot of mileage.

Third, fully synthetic engine oil, in the entire engine oil system, fully synthetic engine oil is the best lubrication effect, and the cycle is also the most searching, so generally speaking, high-end cars will use fully synthetic engine oil, but as people love their own cars more and more, the general car will also use fully synthetic engine oil, and the car replacement cycle using fully synthetic engine oil is about 10,000 kilometers.

After reading the analysis for everyone, don't listen to the advice of some 4S shops or maintenance shops, so it would be a waste to replace 5000km. The main role of the engine oil in the car is to ensure the lubrication and smoothness of the car engine in the process of operation, the specific situation is analyzed, there is no need to change 5000km once, which kind of oil you use, you can replace it at the corresponding time, of course, 5000km to replace it is also possible, unless you are a master who does not care about money.

First of all, let's talk about the most familiar engine oil, because this is necessary to change every time you maintain it, but how often you change the specific void depends on the type of engine oil, for fully synthetic oil, semi-synthetic oil and mineral oil have different time standards, respectively, 10,000 kilometers, 1,500 kilometers and 5,000 kilometers for those who are blind and seven returns, so to change the engine oil is to understand the type of oil of your car, and make a replacement plan according to it, and you must not generalize.

First of all, we have to know about engine oil, the general engine oil is divided into fully synthetic engine oil, semi-synthetic engine oil, mineral oil, different engine oil quality is not the same, its price is not the same, we carry out the classification of the dry report, the full synthetic engine oil is better, the service life is close to 10,000 kilometers, followed by the semi-synthetic engine oil, the service life is around 8,000 kilometers, and finally the mineral oil, the service life is around 5,000 kilometers. Therefore, we can summarize a result, how often to change the engine oil needs to see what type of bright engine oil is applied to the car, not static, the general car instructions are all written every 5000km to change the oil, <>

This is a very commercial insurance practice, are better for the car, but not the most suitable, if you use a fully synthetic oil or semi-synthetic oil, so it is a bit of a waste, so it also needs to be detailed in-depth analysis, at the same time we also need to analyze the use of the car, if the safe driving natural environment is weak, we are likely to need to change the oil earlier, which completely depends on everyone's mastery of the car, so we must not blindly follow the trend to follow others, How familiar you are is the way to do commercial insurance. There is nothing in the world called for sure, the same is true for cars, everyone's driving habits, safe driving natural environment, car use frequency and other aspects are big and small differences, suitable for others may not be very suitable for themselves, to their own mastery, multi-faceted others to seek professional knowledge about the car and then combined with their own feelings.

After buying a new car, most 4S shops will tell the driver that they still remember to change the engine oil once after 5,000 kilometers. In the long run, 5,000 kilometers became the norm for changing oil. In fact, the duration and kilometers of oil change are all set by human factors, and there is no standard to discuss.

However, automobiles belong to machinery and equipment industrial supplies, and the oil should be changed as soon as possible, as long as there are no disadvantages. In order to improve the service life of the car, the driver is gradually becoming more and more diligent in changing the oil. Numerous fans are asking:

If you change the oil once in 5000 kilometers, is it stupid and has a lot of money, and how to maintain it is correct.

There is no specification for changing the oil, it is only related to the application cycle time of the oil. Most taxis change their oil once a month. Frequent oil changes add to the conclusion that after driving safely for more than 30.5 million kilometers, the engine of the car is still in very good condition and will not cause maintenance problems.

But it is unlikely that a private car will be changed once a month, which is extravagance and waste. After all, the use environment of taxis is different, and changing once a month belongs to the normal replacement cycle time. The concept of changing the engine oil for 5000 kilometers should be changed, and the oil change is related to these 3 elements.

The best engine oil is fully synthetic, and it is generally used in luxury brand models.
