What does oil life mean? How long does the average engine oil last?

Fully synthetic motor oil has a lifespan of 10,000 km or one year. In reality, the life of engine oil is not a fixed value, because there are many objective factors that can affect the life of engine oil.

The liquidity of fully synthetic engine oil is definitely better than that of mineral engine oil, but there is no best engine oil only the most suitable engine oil, careful friends can find that Japanese models generally do not have high requirements for engine oil, and German car oil is generally fully synthetic, if it is a turbocharged engine full synthesis will be better, but it is enough for ordinary naturally aspirated engines to use semi-synthetic.

Driving in most cities in China, the use of fully synthetic engine oil can be changed every 10,000-12,000 kilometers or 1 year. Similarly, if you are in a very harsh environment, such as dusty conditions, very low temperatures (below -20), or long distances (up to 8 kilometers per drive). As long as one of the above three factors is met, it is recommended to advance the oil change interval to 7000-8000 km. Hope!

The life of the engine oil is used to help the owner judge when to change the engine oil, and the life of different engine oil will be different, and the life of good quality engine oil will be long. But now the life of the engine oil is generally short, and it is easy to attenuate, like the fully synthetic engine oil is about 5,000 kilometers to attenuate. It is still imported GT Magic Red engine oil is more reliable, with a decay period of up to 10,000 kilometers, and the oil life is longer, and the driving experience is good.

1.Oil life is a computer software program on a trip computer that helps the driver determine when to change the oil based on the engine's operating condition.

2.Oil life is a complex algorithm that calculates the optimal time to change the oil by taking into account various process factors that affect the change in oil life.

3.The life of the engine oil cannot replace the role of the oil dipstick, so the daily oil level check is still a must. Pay attention to check the amount of oil at ordinary times, and whether it needs to be added. Don't be too deliberate about oil life.

Do you want to change the oil? How often do you change it? There are many opinions on the Internet.

On average, it's about 6,000 to 8,000 kilometers, or about 7 months. The exact time is up to you. At this point, you need to decide for yourself whether you need to change the oil.

Actually, it's not that hard. Take a look at these places.

Symbol. Oils can be divided into mineral oils, semi-synthetic oils, and fully synthetic oils. Nowadays, private cars basically use synthetic motor oil, and I won't mention the other two.

In general, the lifespan of all synthetic motor oils is 10,000 km or once a year. In reality, the lifespan of engine oil will fluctuate to a certain extent, which will be affected by the environment and driving style.

When the life of an oil reaches its limit, there are some signs. If there is a sign of the stool, no matter how long the oil has been used, the oil must be changed. If you don't change the engine, you will suffer.

First of all, when the vehicle is moving, the fuel in the internal combustion engine will not burn sufficiently, resulting in carbon deposits. As the engine continues to operate, carbon deposits are gradually deposited in the oil. Generally, motor oil is black, which is the dissolved carbon deposit and oxidation product in the oil.

You can use the oil test strip to observe the condition of the oil. Remove a small amount of oil from the dipstick and drop it on the test strip. When the oil is completely diffused onto the test strip, precipitation rings, diffusion rings, and oil rings appear on the test strip.

If the edges of these three parts are harder, the performance of the oil will be worse. If a test strip is not available, it can also be identified with a clean white paper towel. If the color is black after diffusion, and there are impurities on the paper towel, it means that the oil is dead.

In addition to the color, the driving feel also reflects the performance of the current oil. If you feel that your car is slowing down or that the power is not as strong as it used to be, the "expiration date" of the oil is down and it's time to change the oil. If the power of the vehicle is significantly improved after changing the new engine oil, it means that the maintenance is relatively late, and it can be a little earlier.

Class. As mentioned above, the service life of synthetic motor oil is about 10,000 kilometers, but the service life stated on the Internet is much lower than this value, because the two values do not represent the same oil. Mineral oil has the shortest service life, and needs to be replaced once every 5,000 kilometers or half a year.

The semi-synthetic oil cycle is slightly longer, and it can be changed once at 7500 km; The maximum service life of synthetic engine oil can reach 10,000 kilometers, and the performance of synthetic engine oil is much higher than that of the other two engine oils. For example, this engine oil, such as Kiki Super Bright, is better at dealing with low-speed pre-ignition, anti-oxidation, anti-wear, and fuel economy, which can fully protect the engine.

At present, the basic products of our own cars are synthetic engine oil, and the replacement cycle is too short under the same circumstances. Don't be fooled by the overwhelming amount of information available online. If you buy an oil that is durable, it will last longer.

Summary. Oil is as important to a vehicle as blood is to the human body, so the replacement interval does not have to be too short, so the economy will take a serious hit and it will not be able to be replaced for a long time. After a long time, the engine may not be replaced next time.

Millions of car purchase subsidies.

Engine oil plays a role in lubrication, cleaning and other functions of the engine, its use is very large, can be a good protection of the use of the engine, so what does the oil life mean?

In fact, the life of engine oil is to put it bluntly, the length of time that the engine oil is used, which can also be understood as the aging time of the engine oil, or the degree of cleanliness of the engine oil and the degree to which there is no loss of viscosity characteristics. When the life of the engine oil exceeds the specified years and mileage, it is necessary to change the new engine oil, because the engine oil also has a shelf life, when the shelf life of the engine oil has passed, the lubricity and adhesion will be reduced, which will cause unnecessary wear and tear of the engine. In addition, when the mileage reaches a certain standard, the content of metal chips in the engine oil will reach the upper limit, and the metal chips will also cause certain wear to the engine.

The engine oil with a long mileage will contain sludge, and if it is not cleaned up for a long time, it will cause certain damage to the engine.

The oil life of the engine oil is 100%, but with the increase of time and kilometers, the oil life will gradually decrease, under normal circumstances, when the oil reaches about 20%, it needs to be maintained, and then all need to be replaced with new oil.

Pacific Automobile Network] The life of the engine oil is the time when the engine oil is used. When the oil is used for more than the specified years, mileage must be replaced, the oil also has a shelf life, if the shelf life is exceeded, the lubricity and the rental of the oil will be reduced, resulting in unnecessary wear and tear of the engine.

The service life of the machine is not calculated according to the mileage, but according to the running time of the engine. The life of a normal engine oil is between 100 and 150 hours, and the life of a synthetic oil can reach 200 to 300 hours. When the manufacturer proposes to replace the mileage, it is calculated according to the following method, assuming the speed of 80 kilometers per hour, then 100 hours of operation is 8000 kilometers to 12000 kilometers, change the ordinary engine oil, the owner should drive about 5000 kilometers, and change the oil once.

Since the engine oil has a great impact on the performance and life of the engine, it should be strictly in accordance with the provisions of the automobile instruction manual, and the same series and viscosity grade of engine oil should be selected. The engine oil recommended in the vehicle manual is based on the performance of the engine and the temperature of the sales area, which has a certain guiding role in the selection of engine oil, and leaves a large safety factor, and is also one of the prerequisites for claims during the engine warranty period.

The life of the oil can be understood as the maintenance period of the oil, which needs to be replaced after a period of use. You can do this by time or miles. Like semi-synthetic engine oil, 5000 kilometers or half a year, the whole synthetic engine oil is slightly better, it can be 7000 to 10000 kilometers, about a year.

When the oil life is less than 30%, you can still use the car without causing any danger. After all, this tip is estimated based on maintenance records, which can be said to be relatively accurate. But if there is only 5% or even lower in the hidden defeat, it is better to go to the 4S shop for maintenance (oil change).

Because the engine oil is likely to have deteriorated at this time, it will not only lose the original lubrication and cooling effect of the engine oil, but also cause serious wear and tear of some parts of the engine in the long run. But the data is dead after all, and it still needs to be decided according to the actual situation. First, observe the color of the oil.

If you notice that the color is much darker than before, you may even find obvious impurities floating on the surface, which means that the oil cannot be used at this time and needs to be replaced. Secondly, we can judge by the sense of dependence on the car. If we feel that the engine is visibly shaking, and the nose is getting louder and louder, then we must go to the 4S shop to change the oil as soon as possible.

Of course, we can also use the scientific oil test strip method to determine whether the oil needs to be replaced. First, pull out the dipstick next to the engine, then take out a small amount of oil drops on the oil test strip, let it stand overnight, and wait for the oil on the test strip to diffuse completely. Then you can observe the deposition ring, oil ring, and diffusion ring on the test strip.

If the following three conditions occur, it means that the oil needs to be changed (performance degradation is severe). 1.The three rings are well-defined and can be used for a while, but they still need to be replaced as soon as possible.

2.The oil ring disappears, leaving only the sedimentary ring and the diffusion ring. Go to the nearest car repair shop for a replacement.

Of course, it is also possible to replace it yourself. 3.Only the darker deposition rings remain, which must be replaced immediately, otherwise it is easy to damage the engine.
