Change the oil after running 5000 kilometers? Several aspects affecting the life of engine oil

Many car owners go to 4S shops for maintenance, even if their cars have passed the warranty period. Although the 4S shop is easy to maintain, it really doesn't save money. Even in some places, in order to make car owners maintain more and over-maintain, it is required to change the oil filter after running 5000 kilometers. Engine technology is very advanced at present. Why is the standard of oil change still the routine of 10 years ago? So when should I change the oil? Can synthetic engine oil really change 10,000 kilometers? Today, I will talk about several aspects that affect the life of oil. If you understand, you are not afraid of being fooled.

Engine factory (picture shows Mercedes-Benz) oil certification is stricter than API.

Car oil is first of all products that meet the manufacturer's oil certification. This is the first thing to be guaranteed. If you use engine oil with the wrong model and parameters, don't change it every 5000 kilometers, even if you run 500 kilometers, you should change it in time. How to choose the engine oil suitable for your car is not introduced in detail in this article, please refer to this one:

Several aspects affecting the life of engine oil

The first is the quality of the oil:

It is said that synthetic engine oil can change 10,000 kilometers of oil as a whole, but synthetic engine oil is divided into three grades as a whole, and it depends on what the base oil ratio is in synthetic engine oil. Synthetic engine oil, mainly GTLⅲ III oil, with an insurance replacement mileage of 8,000 kilometers; In synthetic engine oil with PAO as the main oil, the insurance replacement mileage is really10000 km; In synthetic engine oil, where five types of base oils are dominant, such as lubricating grease engine oil, the replacement cycle is compensated, because lubricating grease is not durable and easy to oxidize, and the insurance replacement mileage is also 8,000 kilometers. So, how to judge whether all synthetic engine oil is based on PAO, and which certification must be high-end all synthetic engine oil? Please refer to this article:

What is the real synthetic engine oil? You may have been fooled.

Secondly, it is related to the environment inside the car.

The influence of rain and snow weather on engine oil is far less than that of sand and dust weather. Driving in dusty places often requires not only frequent replacement of air filters and air conditioning filter elements, but also replacement of oil in advance. In addition to environmental factors, in areas where ethanol gasoline is used, ethanol will be oxidized into acetic acid to neutralize the alkalinity in engine oil. Even if the long-term high base number is in synthetic engine oil, it will not prevent the "acidification" of ethanol gasoline. Urban traffic jams and insufficient fuel combustion will inevitably produce carbon deposits and gasoline mixed oil, just a matter of how much. Whether carbon deposit or gasoline is mixed with engine oil, it will reduce the life of engine oil. Based on the above comprehensive consideration of the vehicle environment, when changing the oil for your car, you should try to choose all synthetic engine oil, and it is more appropriate to change the oil between 8000- 10000 km. Therefore, the automobile environment has a great influence on the oil, and it is necessary to change the oil in advance.

If you have good road conditions and use pure gasoline, and there is not much dusty weather, whether it is mineral oil, semi-synthetic or fully synthetic, you can change the oil according to the standards of 5000, 7500, 10000 km. The best example is taxis in first-and second-tier cities. The engine oil used is not very good, but the engine rarely breaks down after running for hundreds of thousands of kilometers.

Third, it is related to driving style.

Except for frequent red line acceleration and big foot throttle, the attenuation of oil will not be too obvious. On the contrary, frequent violent driving has a great influence on the life of engine oil. When driving violently, the working condition of the engine is bad, the temperature and friction are more intense, and it is easier to break the carbon chain molecules in the engine oil, thus losing its protective effect. If you often drive violently, you can choose higher-end track oil. If you race in the site run, you should change the new oil after the race.

Finally, it is related to somatosensory.

This is also the most metaphysical place, and people who are very sensitive to the driving situation of their cars have experience. When you feel that the engine noise is getting louder and louder, it is difficult to start cold, and the speed of stepping on the accelerator is going up, but the speed is rising slowly and the acceleration is weak, you should consider whether to replace the new oil. In addition, although 65,438+00,000 kilometers can be exchanged for the whole of synthetic engine oil, the driving experience of the last 2,000 kilometers is not good. At this time, you can also consider changing the oil in advance. In addition to considering the number of kilometers, the running hours of the engine can also be used as an alternative. According to the domestic road conditions, synthetic engine oil can be replaced in about 250 hours, and it can be replaced in about 300 hours if the road conditions are better. At present, many long-acting engine oils can be changed once every 20,000 to 30,000 kilometers abroad, which is basically impossible to achieve in China.

When to change the oil, there are many aspects to consider. If you are too lazy to study so much, you can change it according to the maintenance manual of the manufacturer's manual. Of course, it also depends on what kind of oil the 4S shop changed for you. If you spend more money to buy all of synthetic engine oil, but still let you change the oil every 5,000 kilometers, you must earn more money than you; If you use cheap semi-synthetic engine oil or even mineral oil, it is more reliable to change the oil every 5,000 kilometers. In addition, many old drivers are not in 4S stores for maintenance, and changing the oil depends entirely on their mood. The engine is loud, and the throttle doesn't follow their feet. Just change the oil. Changing oil and water frequently is only good for the car, not bad, just a waste of money.
