With the original engine oil, the power decline is obvious, and the car changes the oil for many kil

Normal 5,000 kilometers can be used to change the oil.

Changing the engine oil every six months refers to a relatively matter, not a hard indicator. Although the kilometers have not arrived, because the new car in the run-in process, there will be some metal particles precipitated in the oil, if there are many metal particles, the oil will be carried to other parts, which will bring certain damage to the engine.

1. When should I change the oil of the car?

Engine oil is the lifeblood of an engine, it is the component that cools and lubricates the engine. The car should be oiled regularly. Basically, it will be clearly written in the manual of every car.

In the past, the standard was 5,000 kilometers per kilometer, but in recent years, car manufacturers have continued to develop research and research to improve the construction of engines and extend the time required for regular maintenance and oil changes. Therefore, many new cars can basically change the oil every 10,000 kilometers if they use synthetic engine oil under general driving conditions, and some can even drag it up to 20,000 kilometers. "Ordinary driving" refers to driving on the highway a lot and rarely stopping and walking.

However, if you often drive in the city, there are traffic lights when you go to **, you will be stuck in traffic at every turn, and most of the distances of each trip are not more than ten kilometers, this kind of driving method belongs to "attritional driving". In the case of "weary driving", the engine wears a lot and the oil demands are high. Therefore, it is advisable to shorten the interval between oil changes in order to effectively protect the engine.

2. Usually, it is difficult for us to decide whether the oil should be changed by the naked eye or touch, but after long-term use, the oil will accumulate a large number of impurities, if the new oil is not replaced in time, these impurities will wear out the engine for a long time and shorten the life of the car.

3. How to choose engine oil.

Choosing a good engine oil can make your car more durable and powerful. A good engine oil, especially a fully synthetic one, can not only protect the engine and reduce the number of oil changes, but also save on gasoline costs. So it is the best choice for many car owners.

4. Pay attention to four elements when purchasing engine oil.

1) The choice of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade oil on the engine with lower requirements, nor can the oil of the lower grade be used on the engine with higher requirements.

2) Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the engine due to saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

3) The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of similar imported products, so it can be used with confidence, and there is no need to blindly pursue "foreign oil".

4) If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil path smooth. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

Changing the engine oil every six months refers to a relatively matter, not a hard indicator. However, for a new car, I would recommend that you change it. Although the kilometers did not arrive.

Because in the run-in process of the new car, there will be some metal particles precipitated in the oil, if there are many metal particles, they will be carried to other parts by the oil, which will bring certain damage to the engine. Therefore, it is not necessary to wait until the number of kilometers is up to change, from the perspective of the car, in the long run, it is not a big deal to change a little early.

Half a year must be changed, after half a year the oil will have emulsification, but the naked eye can not see, you can pull out the oil dipstick to touch the oil, you can feel the viscosity of the oil is much thinner, in the case of cold engine viscosity will be dilute will aggravate the wear of the engine.

The oil will deteriorate after a long time, but it does not have to be half a year, and the problem is generally not too big within a year. It is recommended that the replacement cycle should not exceed one year at the latest.

Replacement is recommended.

There are two cases of oil change.

One: the mileage reaches about 5000 kilometers.

Two: half a year.

Three: the engine oil is deteriorated, dirty and has impurities.

In fact, the oil change is practicalThere is no fixed oneTime. The most important thing is to judge according to the owner's own situation. Normally, if you're new car, the initial guarantee is 5,000 km or three months.

In this way, if you don't have 5000 kilometers in 3 months, you also need to go for a first insurance.

Introduction:

The role of engine oil is mainly to clean, cool and lubricate the engine, ensure that the internal parts of the engine are reduced when the engine is working, and can also play a role in sealing and leakage, rust and corrosion. The normal consumption of engine oil is very small, and the reason why we need to change the engine oil is due to the oxidation of esters and polyolenes in the oil. In addition, particles from the wear of parts in the engine can also enter the oil, reducing the life of the oil and deteriorating the internal composition.

There are three types of engine oil on the market: mineral oil, semi-synthetic oil, and fully synthetic oil. For example, the replacement cycle of ordinary mineral oil is half a year or 5,000 kilometers, the replacement cycle of semi-synthetic engine oil is about 8 months or 7,500 kilometers, and the replacement cycle of fully synthetic engine oil is 10,000 kilometers a year.

It is necessary to change. Because after the oil is opened for more than six months, due to oxidation, pollution and other factors, the viscosity of the oil decreases, and the lubrication performance decreases, so it is recommended to change the oil if you start to drive the vehicle continuously.

If the car is not driven for a long time, do I need to change the engine oil when I open it again? Listen to what the old driver has to say.

Per cent. Generally speaking, when the service life of the engine oil is less than 20%, it needs to be replaced, but it should also be judged according to the setting of the driving computer.

It is recommended that the owner change the engine oil in time to avoid abnormal wear and tear of the engine when driving, which will affect the normal use and shorten the service life of the engine.

Mixing of different brands of motor oil:Different kinds of engine oil addition will also cause the phenomenon of lubrication decline, although the base oil of the car is the same, but different types of different brands of engine oil, additives are different, so the performance and grade of the engine oil are different, rashly mixed oil use may occur chemical reaction, destroy the performance of the oil, is also a relatively large threat to the engine.

Generally, the engine oil is 5000 kilometers and 180 days, and there will be some oxidation in the oil when exposed to the air for a long time, so your engine oil needs to be changed now!

Generally, it is replaced once every 5000 kilometers, and if it is not used often, it can be postponed, but it is necessary to pay attention to the type of engine oil, such as winter engine oil, summer engine oil. Hope it helps, thank you!

Time and kilometers are not the only criteria for considering whether to change the oil, if it is not necessary to maintain it within the specified time, you can check the color, smell, and impurities of the oil, and if it is all right, you can change it later.

The oil change is limited by two factors: running time and mileage, which expires first and changes according to which period. Because engine oil has a shelf life, engine operation will accelerate the deterioration of the oil. For example:

Use ordinary engine oil, run for 5000 kilometers for about half a year; Semi-synthetic engine oil is used, and it is replaced in about 9 months after running for 7500 kilometers; It uses fully synthetic engine oil and is replaced in about 1 year after 10,000 kilometers of operation.

It should be noted that the replacement cycle can be appropriately shortened or extended according to factors such as engine status and operating environment.
