What is the oil change interval? Do you need to look at the number of miles to tell the difference?

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.

Take a look at the owner's manual, according to the instructions on the manual to determine the oil change cycle, generally 5000-7500 kilometers for a replacement cycle, each time the oil should be changed at the same time as the oil filter. Vehicles that often drive in urban areas can shorten the oil change interval accordingly; Vehicles with semi-synthetic or fully synthetic oils can consider extending the oil change interval appropriately.

If you use mineral oil, because it contains more impurities, the oil performance is poor, and it needs to be replaced frequently, about 5000 kilometers. Fully synthetic motor oil contains almost no impurities, is far more stable and anti-aging than mineral oil, and can be used for a long time, about 7500 kilometers. The use of lubricating oil with good anti-wear performance such as Kunlun Lubrication KR9-T can effectively extend the service life of the engine; And the oxidation resistance is also good, which can extend the oil change interval, about 12,000 kilometers can be changed.

The oil change cycle depends on the oil you use, 6 months or 5000 kilometers for ordinary oil; semi-synthetic motor oil for 8 months or 7500 km; Fully synthetic motor oil for 12 months or 10,000 km.

The best thing to say is to do a maintenance, the oil and everything for you to get it, don't worry about it yourself, and it can also extend the life of the car.

It's not easy to hit by hand, hope.

It mainly depends on what kind of engine oil you add. In the case of full synthesis, it may take a little longer.

After the warranty period, who will come later! Usually maintained once a year, such as more than 10,000 kilometers per year, the selected engine oil can be.

The oil will be changed in half a year. Because the engine oil will oxidize and deteriorate after half a year of alternating use of hot and cold.

There is no automatic or manual oil for the engine.

The kilometers or times on the maintenance manual whichever comes first will go.

Kill Alto and don't explain, the god car.

Statistics show that 60% of engine failures are caused by wear, but the right oil can not only improve engine performance, but also reduce wear. However, once the oil is added too much, used for too long, and the viscosity is too high, it will also bring drag to the engine and cause fuel consumption to increase. In the end, the oil must be added, the question is by kilometers or by time?

In the manufacturer's vehicle maintenance, the engine oil maintenance will require time in addition to mileage. So is it based on mileage? Or according to the time?

In fact, it is safest for everyone to follow the first-come-first-served principle. Let's talk about it first, the first insurance must be changed.

How to change the engine oil for the first insurance?

Let's take a look at the first insurance, generally speaking, the first warranty time of a new car has a specified mileage and time, if your new car first warranty is 5000 kilometers 6 months, then if you are less than 5000 kilometers in half a year, then ignore the time and where to go to maintenance; And if the new car is bought and not driven much, even if it is less than 5,000 kilometers in half a year, then you have to do the first insurance, and you must not delay, after all, the first insurance is very important for the new car.

How to add engine oil after the first warranty?

After the first warranty of the new car is completed, the subsequent maintenance nodes will depend on the specific use.

Judging from the maintenance manual, the standards for changing the engine oil are different for each car brand, but generally speaking, as long as the mileage and time specified in the car are carried out in advance or slightly delayed, the maintenance is not a big problem. However, there is another point to note here that the oil product level added to each car is different, which will also directly affect its replacement cycle.

Generally speaking, if the engine uses mineral oil, basically 5000 kilometers 6 months to change, semi-synthetic oil can be 7500 kilometers 6 months to change, fully synthetic machine can be 10000 kilometers 12 months to change.

What should I do if I don't get Miles or Time after the first insurance?

Of course, some car owners usually do not have many opportunities to drive, which leads to the required maintenance time, but the driving distance is far less than the required mileage.

For example, after the first insurance, you can drive less than 5,000 kilometers of this kind of car for a year, and add fully synthetic engine oil, so can you leave it alone and change it when you reach the specified mileage? In fact, everyone should have heard the saying, that is, "cars are broken". Even if the car is not driven, it cannot be left unattended for a long time without changing the oil and maintaining it.

Because from the point of view of engine oil, it also has a shelf life, and if the oil is not changed for a long time, the viscosity of the engine oil will be reduced, and even deteriorated and emulsified, thus losing the original Zen performance.

One of the functions of engine oil is to help the engine reduce the wear between various components, if this anti-wear performance is reduced, then the engine is directly harmed. Therefore, even if you don't usually drive, you still have to do engine maintenance when it comes to the specified maintenance time.

In most cases, the filter is changed every 5000 km, but if it is not 5000 km, as long as the oil is changed, the filter is generally changed together. A machine filter is only ten or twenty yuan, and it doesn't hurt to change one. For some long-lasting engine oil cars, such as 8000km or 10,000km to change the oil once, you can also choose some long-lasting engine filters, some can reach 8000km life, but ** will be slightly more expensive.

Generally, after half a year or 5000 kilometers, the oil change time and kilometers should be changed: 1. The service life of general mineral oil is half a year, the service life of semi-synthetic engine oil is nine months, and the service life of synthetic engine oil is one year; 2.

After a period of time, the oxygen in the air will react with the additives in the oil, thereby weakening or disappearing the protective effect of the oil. Therefore, after a certain period of time, the engine oil must be changed; 3.In actual use, it should be adjusted according to the specific use case.

For example, low-speed driving, short-distance driving, low-temperature driving, and poor local fuel quality are delayed. At the intersection of urban congestion, in these cases, the oil change interval should be appropriately shortened; If the engine is always in good road condition and works more at economic speeds, the oil change interval can be extended appropriately.

Lubricants are divided into fully synthetic, semi-synthetic and mineral oils, and the service life of these three types of engine oils is different.

Under normal circumstances, it is better to replace the fully synthetic oil within 10,000 kilometers; The number of kilometers for semi-synthetic oil is 7,500 km, and the lowest grade of mineral oil needs to be changed within 5,000 km. However, in addition to the number of kilometers as a reference, there is also the time of use of the engine oil to measure, in general, the replacement cycle of fully synthetic oil is 1 year; Semi-synthetic oil is within 6-8 months; Mineral oil, on the other hand, needs to be replaced within six months.

In addition to judging the change of engine oil by the number of kilometers traveled by the car, the rotten answer should also be combined with the time of using the engine oil, which of these two parameters needs to be replaced first. However, it is recommended that car owners should change the engine oil a little in advance to avoid waiting until the oil deteriorates before changing it, which is easy to cause some damage to the engine.

How to determine if the oil needs to be changed

Under normal circumstances, there are certain precursors before the oil is replaced, such as increased engine noise, or the oil lamp will flash to prompt. At the same time, we can also use the oil test strip to test the quality of the oil, the following are the operation steps:

1. Prepare a blank oil test strip;

2. Use the oil dipstick to drop a drop of oil to the oil test strip**;

3. Observe the change of engine oil on the test strip, if the oil is divided into three layers, the outermost layer is the oil ring, the middle layer is the diffusion ring, and the innermost layer of black is the oil deposit, which means that the oil needs to be replaced;

4. If the oil is not clearly layered on the test strip, there are only two layers, and there is no obvious black matter in the middle, it means that the oil can continue to be used.

Similarly, the oil test strip can also be used to detect whether the oil is new, and when the test strip shows that it is not stratified and very clear, it can prove that the oil has not been used.

The replacement cycle of fully synthetic motor oil is generally 7,500 to 10,000 kilometers, or 7 to 12 months. Everything is based on the replacement cycle guided by the manufacturer, and the durable ones have high technical requirements and are more expensive. When it comes to the replacement cycle, no matter which condition is achieved first, you must not be reluctant, if you do not replace it in time, the damage to the engine is great.

However, the most appropriate way to change the engine oil is to look at the use of the engine oil, which is mainly in terms of color and condition.

The first arrival is the case, and the kilometers can be changed when the time is upGenerally, the first warranty maintenance period is 3 months, and it is recommended to replace it when it expires, and then it can be replaced according to the maintenance manual for 5,000 kilometers or 10,000 kilometers.

In fact, mileage is only a standard for maintenance and oil change, and it is clearly marked in the vehicle maintenance manual, and for oil change, in addition to mileage, time will be required. That is to say, even if the mileage of the car does not meet the maintenance standard, but the time is reached, it is still necessary to go for maintenance and oil change.

The role of motor oil.

1. Lubrication and wear reduction.

A layer of oil film is formed on the surface of the two sliding parts, so that the parts will not be rubbed when running, and the parts will run smoothly.

2. Clean and dispersed.

Good engine oil can wash the dirt on the surface of the parts and components through the flow of oil, absorb some tiny metal debris in the engine, and then scrape off the oil pan by the piston oil ring.

3. Cooling and cooling.

When the engine is running, it generates high temperatures, and when the oil reaches the running part, it will absorb the heat, and then take the heat away to assist the parts to dissipate heat.
