Is it necessary to change the oil after 5,000 kilometers of the newly bought car?

Of course, it is necessary, the engine of the new car has indeed been run-in before leaving the factory, but in the run-in of the manufacturer, it is only cold run-in and is low-speed, and it still needs to be run-in after buying it back. After 5,000 kilometers, the iron impurities that fall from the various parts are mixed in the engine oil. So it has to be replaced.

I don't feel like I need to. Because it's a new car. Specifically, it is necessary to look at the color of the oil, if there is blackening, debris, and loud noise from the engine, it is necessary.

There are 5000 km or 10000 km change brands of engine oil, and 5000 km to change the engine oil is the best way to maintain the car

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.

It is easy to buy a car and difficult to maintain a car, in addition to refueling, the most "troublesome and expensive" thing for car owners is maintenance. Oil maintenance is one of the most important things. First of all, we need to understand what motor oil is used for.

Engine oil is the engine lubricating oil, which mainly plays the role of lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage, rust and corrosion prevention, shock absorption and buffering, etc., and is known as the "blood" of the car. If there is a problem with the oil, the engine will go wrong and the car will have a problem.

As for how the 5,000 km oil change came about, there is a saying that there is a fast repair chain in the United States called Jiffy Lube, and every time a car is maintained, a paper will be posted on the front windshield to remind you to do maintenance at this time or mileage, and Jiffy Lube's standard is 3,000 miles (4,800 km).

However, with the improvement of engine oil quality, this standard has long been outdated, and now domestic 4S stores require 5000 kilometers of maintenance, mostly for profit. Because the competition in the automobile market is becoming more and more fierce, it is no longer very profitable to sell cars, in order to maintain sufficient profits, we can only start from the after-sales service, and shortening the maintenance cycle is one of the means.

If the manual indicates that it is 5000 kilometers a maintenance, it is necessary to do maintenance, if the manual is 10000 kilometers, it is not needed, different models, different models have different maintenance mileage requirements.

Notes:Replace twice a year can better protect the engine, if you use the car for a long time, run seven or eight thousand a year, one or two thousand kilometers, and maintain it twice is just right. If you run five or six thousand a year, it is recommended to replace it with four or five thousand.

As a reminder, it's not that the less the engine runs, the better. Car engines.

If it runs for a long time or runs 20,000 kilometers a year, the engine oil can better protect the engine.

It is necessary to change the oil on time, the normal situation is to drive 5,000 kilometers or change the oil every six months, whichever standard comes first.

The oil in the car has a variety of functions such as lubrication, cooling, cleaning, and sealing, so it is necessary to change the oil on time, according to the strict requirements of driving 5000 kilometers, to change the oil once, or to change the oil every 6 months, which of the two conditions is met first, according to which implementation, but the maximum period of replacing the oil can not exceed one year, even if it only runs 2,000 kilometers a year, it is necessary to change the oil.

1. Why do you have to change the oil?

There will be a certain amount of consumption after the oil is added to the engine, and the oil after opening has a shelf life, and its maximum shelf life in the engine will not exceed 8 months, so it is necessary to replace the oil in time during its shelf life.

2. Regularly judge the quality of engine oil

Some people feel that their car only runs 5000 kilometers a year, there is no need to change the oil, this idea is wrong, if you don't want to change the oil every 6 months, you can often monitor the quality of the oil in the engine at a time, you can use the oil test strip to test the appropriate amount of oil drops on the test strip, see its diffusion, judge the quality of the oil, if the color of the oil is dark, the diffusion ring is relatively wide, indicating that the oil has been polluted, but you can continue to use, if the sediment is black, and the sediment is dense, It means that the engine oil has deteriorated and can no longer be used, and must be replaced as soon as possible.

3. The hazards of changing engine oil from time to time

Changing the oil from time to time will have many hazards, and it will affect the normal driving of the vehicle when it is serious, because changing the oil from time to time will lead to serious wear and tear of the internal components of the engine, increase the noise, and increase the fuel consumption of the car and decrease the power.

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.

This is necessary because changing the oil can improve fuel economy, and then it can also extend the life of the engine, which can achieve efficient maintenance and clean up the carbon deposits in the engine.

Of course, it is necessary, and the engine oil needs to be changed every year, so as to ensure the safety of the vehicle and ensure the normal operation.

It is necessary to change the engine oil, because the role of the engine oil is relatively large, it can be lubricated, and it can reduce wear.
