How often should car oil be changed? Is 5,000 kilometers a myth?

It should be changed once every six months, 5000 kilometers is sometimes a misunderstanding, if the car does not run often, then it should not be judged according to the number of kilometers, but according to the time.

It's about 5,000 kilometers to change every time, and it's not a misunderstanding. Because the speed is maintained at 80 km/h, the maximum capacity of the oil is 5,000 km/h.

It's about 30 kilometers to replace it. It is a misconception that many people think that being able to run so many kilometers leads to the lack of oil storage, which ultimately leads to a reduction in the life of the car.

The car has entered everyone's life, but also to everyone has brought great convenience, and the car is always just a mechanical product, long-term use will lead to the frequent failure rate of the car, so in order to reduce the failure rate of the car to do regular maintenance. How often to change the car oil is actually determined according to the nature of the engine oil, if the use of fully synthetic engine oil can be changed every 10,000 kilometers; If you are using semi-synthetic oil or mineral oil, change it every 5,000 kilometers. And whether it is a mistake to change the engine oil of the car every 5,000 kilometers should also be determined according to the type of gasoline.

First, the car uses fully synthetic engine oil, which can be changed every 10,000 kilometers.

For the engine oil, the market is roughly divided into three types, namely fully synthetic engine oil, mineral oil and semi-synthetic engine oil, if the car uses full synthetic engine oil, then the owner can change the engine oil every 10,000 kilometers, because the fully synthetic engine oil has better oxidation resistance and lower viscosity, so that it can effectively protect the internal cylinder block of the engine. However, the owner must use the oil of qualified products when changing the engine oil, and if the inferior oil is used, the gain outweighs the loss. <>

Second, whether it is a misunderstanding to change the engine oil after the car travels 5,000 kilometers should be determined according to the nature of the engine oil used.

For the car, the engine is the core, so for the engine oil is the core of the engine, it is enough to see how important the engine oil is to the engine. If the car travels 5000 kilometers and the oil used is semi-synthetic or fully synthetic, then it is not a mistake to change the oil, and if it is a fully synthetic oil to be replaced, it is a misunderstanding. <>

3. Summary. Generally speaking, the car is an indispensable means of transportation in people's lives, and car maintenance also has a great impact on the condition of the car, so the owner must use good engine oil. <>

It depends on the type of oil 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.

If the oil is not changed for a long time, the lubrication effect of the engine oil will be reduced, and the internal parts of the engine cannot be lubricated when the engine is working, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.

Car oil change intervals. It is determined according to the grade of oil used.

If it is a fully synthetic engine oil, it can be maintained once every 10,000 kilometers (or a year). The specific one shall prevail (the same below). Because of the full synthesis of motor oil, a variety of additives are added, which has a very good antioxidant attenuation ability. Therefore, the replacement cycle is relatively long.

If it is ordinary mineral oil, then the replacement cycle is recommended to be maintained once every five or six thousand kilometers (about half a year). This is because mineral oil is a low-end entry-level motor oil. Its antioxidant attenuation ability is weaker than that of synthetic engine oil. Therefore, the maintenance interval needs to be shortened.

If it is a semi-synthetic motor oil. It is recommended to maintain it once for seven or eight thousand kilometers (or about nine months). As the name suggests, the lubricating effect and oxidation resistance of semi-synthetic motor oils are somewhere between fully synthetic and mineral oils. So the maintenance interval is somewhere in between.

Car oil should generally be changed after 5,000 kilometers. The worst of the engine oil has a greater impact on the working environment of the engine. The engine works in a high-temperature environment, and the mechanical friction movement is constantly repeated, and the engine oil plays a role in cooling, lubrication and cleaning in this project.

Over time, there are more impurities in the oil, and the performance decreases.

Combined with the quality of domestic oil products, the oil can be changed at about 8,000 kilometers, which is a more appropriate time. However, 8 thousand kilometers to change the oil, is not suitable for all cases. Depending on the quality of the engine oil and the different road conditions, the replacement time will fluctuate.

Fully synthetic engine oil has the longest service life, and it can generally be replaced in about 10,000 kilometers if fully synthetic is used. Semi-synthetic oil can be changed up to 8,000 km. Ordinary mineral oil is recommended in advance.

Automobile oil replacement is generally 2500 kilometers for 3 months for the first warranty and 6 months for regular maintenance of 5000 kilometers.

First of all, it depends on whether you are using semi-synthetic engine oil, which needs to be changed every half a year for 5,000 kilometers, and fully synthetic engine oil, which needs to be changed for 10,000 kilometers or once a year. If it is mineral, the oil needs to be replaced for 3000 km or 3 months.

5000 kilometers, or once every six months, is basically maintained by this standard.

The oil replacement cycle depends on what oil is used, fully synthetic engine oil can be changed in 10,000 kilometers, semi-synthetic engine oil can be changed in 7,500 kilometers, and mineral oil can be changed in 5,000 kilometers, I hope it can help you.

Look at the maintenance manual, the time is half a year, the number of kilometers depends on what kind of oil you use, a good fully synthetic engine oil can travel more than 10,000 kilometers.

The first two new cars, within 2000 km, and the next 4000-6000 will do. In addition to mileage, there are many factors, such as road conditions, air conditions, whether you drive more in urban areas or at high speeds.

If the car oil is used well, it can be changed at 5000 for long distances, and 8000 for long-distance runs.

Upstairs is really a textbook answer.

In fact, the timing of oil replacement and mileage are related to the condition of the car, driving environment and habits, etc., and those who are experienced will check the oil texture according to the oil dipstick to determine the replacement.

Under normal circumstances, the replacement frequency of household cars with good vehicle condition and good environment (less smoke, dust, etc.) can be slowed down, and heavy-duty vehicles, with poor vehicle condition and bad environment, need to be appropriately increased frequency.

In addition, 5000 kilometers in half a year (whichever comes first) This data is a bit conservative, and family cars should not be changed so often.

Car owners know that changing engine oil regularly is an important item in car maintenance, so how often should it be counted.

Is it regular? As the version goes into detail, there are three standards for changing engine oil: one is determined according to the mileage of the vehicle (or the working hours of the engine), which is what we often call regular oil changes.

One is determined according to the degree of change in the performance of the engine oil, which is called oil change according to quality. In addition, there is also a way to judge whether the oil should be changed according to the display of the oil quality testing instrument. Although the latter two methods are more accurate, they are more expensive and more troublesome, so most people now determine the engine oil replacement interval based on experience, even if the manufacturer's manual indicates that the replacement time or mileage is only an approximate number.

Therefore, how often to change the engine oil is determined by yourself according to the specific car conditions and refer to the car's manual. For example, if you are driving a new car and using a high-grade good oil, you can basically drive 120,000 kilometers and then change the oil. If your car is not in good condition and the driving environment is average, then shorten the oil change interval, such as every 510,000 kilometers.

Reach the oil service cycle or mileage reached.

It's time to change since 5000 km.

Generally, the service life of mineral engine oil is half a year, the service life of semi-synthetic engine oil is nine months, and the service life of fully synthetic engine oil is one year.

When the engine oil is unpacked and added to the engine, whether the engine is running or not, after a period of time, the oxygen in the air will react with the additives in the oil, so that the protective effect of the oil will be weakened or eliminated. Therefore, after the oil reaches a certain time, it must be replaced.

In actual use, it should also be adjusted according to the specific use case. For example, often driving at low speeds, often short distances, low temperatures, and poor local fuel quality at congested intersections in the city, etc., in these cases, it is necessary to appropriately shorten the oil change cycle; If it is often in good road conditions, the engine works more at economic speeds, which can make the oil change interval appropriately extended.

Engine oil, that is, engine lubricating oil, can lubricate and reduce wear and assist the engine.

Zhi helps cooling and cooling, sealing DAO leakage-proof, anti-rust and anti-corrosion, shock absorption and buffering. It is known as the "blood" of automobiles. Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil.

It is recommended to replace the DAO engine oil according to the relevant label DU and quality DAO specified by the manufacturer. General Edition.

Fully synthetic engine oil should be replaced after 8,000-10,000 kilometers of driving, semi-synthetic engine oil should be changed after 5,000-8,000 kilometers, and mineral oil should not exceed 5,000 kilometers. Vehicles that have not been used for a long time generally change the oil once every 6-8 months.

It depends on the vehicle.

to use the oil source.

Type. bai

Generally, there are 3 types of engine oil, all of which are synthetic.

DU, semi-synthetic, mineral zhi motor oil.

Generally, the whole DAO 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.

Fully synthetic, last year's 12 car review 4S shop changed, ran about 13,000 kilometers and has not changed. Volkswagen STN manual.

Ordinary engine oil, running for 5000 kilometers (about half a year) is the best to replace.

Semi-synthetic oil, 7500 km (about 9 months) is the best to change.

Fully synthetic engine oil, it is best to replace it after 10,000 kilometers (about 1 year) of operation.

The oil change interval mainly depends on the type of oil used.

There are three types of engine oil: mineral oil, half synthetic oil, and fully combined engine oil.

Mineral oil is generally changed every 5000 km or 3 months.

Semi-synthetic engine oil is generally changed every 7500 km or half a year.

Fully synthetic engine oil is generally changed every 10,000 km or 1 year.

The most scientific way is to pull out the ruler to check the oil condition and then replace it.

The correct time to change the car oil.

Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles. Engine oil is made up of two parts: base oil and additives.

Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil.

The correct time to change the car oil.

How to determine the oil replacement time depends on what type of engine oil is used.

Look at what kind of car, the Japanese system is generally 5000 kilometers, and the European system is generally 7500-10000.

The so-called oil change interval refers to the mileage or time between each two lubricating oil changes, which is recommended as 5000 km or 7500 km in the general vehicle instruction manual, or in terms of time, such as 6 months. The interval mileage of Japanese brand cars is mostly 5,000 kilometers, and the cars of German Volkswagen, including Shanghai Volkswagen and FAW-Volkswagen, are mostly 7,500 kilometers. However, due to the combined influence of various factors such as vehicle conditions, road conditions, driving intensity and environment, the oil change interval cannot be simply generalized.

For example, the recommended oil change interval for a compact car produced by an international automobile company in Europe has been increased to 30,000 kilometers, while the similar car produced in China still requires an oil change interval of 7,500 kilometers after examining the domestic environment, road conditions, fuel quality and other issues.

If you use an oil that is of a higher quality grade than the one required in the vehicle instructions, increase the oil change mileage by 15% for each grade raised. If synthetic engine oil is used, for different vehicles, fully synthetic engine oil can generally achieve more than 15,000 kilometers, and semi-synthetic engine oil can achieve 12,000 kilometers of oil change mileage. Under harsh conditions, such as driving on dusty and gravel roads, long-distance driving across climatic zones, etc., it is necessary to shorten the oil change mileage1 3.

Due to the long service life of the old car, the precision of the engine has been reduced, but as long as the engine is in normal working condition, the use environment is good, and the temperature can reach more than -20, the oil change interval of 5000 kilometers is completely feasible. If you drive continuously in dusty areas, it is better to replace it with 5000 kilometers. If driving in areas where the temperature is below -20, the oil change interval should also be shortened.

On the contrary, if the environment is clean and the air is clean, the oil change interval can be extended appropriately.

1. In the past, mineral oil was used, and the oil was changed once within 5000 kilometers. When there is no traffic jam, the average speed of high and low speeds (0-120 kmh) is about 50 km/h. The maintenance method of changing the engine oil once in 5000 km is correct:

50 km h x 100 h (mineral oil) 5000 km (oil change interval for mineral oil).

2. There is no restriction on the driving speed of the engine oil, only the problem of efficiency and fuel consumption.

3. The correct oil change standard is calculated based on "engine running time". (Self-estimated average speed: kilometers per hour) (100 hours (mineral oil) or 200 hours (synthetic oil) Number of oil change kilometers.

4. The safe operation life of general engine oil:

mineral oil for 100 hours; Synthetic oil for 200 hours. Please refer to the following ** Oil change.

Average speed Mineral oil (100 hours) Synthetic oil (200 hours).
