How often is it best to change the engine oil, and must it be changed according to the time of the m

Engine oil has always been silently playing a "supporting role" in the automotive world. People can always think of "big coffee" such as engines and gasoline, but it is easy to ignore the role of engine oil. In reality, there are few things that are evergreen, and engine oil cannot escape the fate of aging and replacement.

How often is it reasonable to change car oil? The following will introduce this situation in detail, which can better maintain the car and drive a higher number of kilometers.

Reasonable change intervals for automotive oil.

1. Mineral engine oil: It is recommended to replace it at 4000-5000 kilometers.

2. Semi-synthetic engine oil: it is recommended to replace it at 5000-7500 km.

3. Fully synthetic engine oil: it is recommended to replace it at 7500-10000 kilometers.

This kind of data can only serve the public, in fact, readers will always have questions and uncertainties about this kind of generalized data. If you consider the efficacy, it is definitely that the sooner you replace it, the better the cleaning and lubrication effect of the oil. The real pocket does not allow it, and the economy is the benchmark for measuring purchasing power, so the above data is for reference only, not for implementation.

The actual replacement interval depends most importantly on the operating conditions and the frequency.

The oil change interval will be indicated in the maintenance manual of many cars, and the manufacturer's advice is the most reliable. If not, the owner can tell if it's time to change the oil of your car from the following methods.

1. The easiest way is to check the oil scale directly, if the oil level is lower than the minimum limit, you should replace the oil with a new one.

2. When the oil is emulsified, foaming, blackening, impurities or viscosity is reduced, the oil should be replaced in time.

3. The engine is abnormal and the noise in the cylinder can be heard. Debris from mechanical friction may enter the oil pan and are constantly carried to the cylinder with a crashing sound as the oil is transferred to the pistons. At this time, there are many impurities in the oil, so the oil should be replaced, and the oil pan should be cleaned if necessary.

4. High fuel consumption, serious engine shake and other phenomena should attract the attention of car owners.

5. The engine temperature is abnormal, or it may be that the cooling system fails due to insufficient oil.

6. There is a harsh sound when the engine is transported, which may be because the viscosity of the oil is not enough, resulting in a decrease in the lubrication effect, and the sealing ring of the piston is directly scraped against the cylinder wall, which is the so-called "pulling cylinder", which will lead to the scrapping of the engine in serious cases.

Fangxiang engine oil is also those ordinary engine oil, which is almost the same as changing once every 5000km. It is better to change the exclusive engine oil than to change the PAO engine oil, which is much more cost-effective. I am now using GT Magic Red engine oil maintenance, the oil is much more cost-effective, 15,000 kilometers for maintenance, maintenance is particularly convenient.

Moreover, the GT is a PAO engine oil, which is of high quality, and the car feels particularly good to drive.

First of all, for fully synthetic engine oil, the recommended replacement cycle is one year or 10,000 kilometers, whichever comes first. The main driver here understands that the change of engine oil is not only based on the mileage, but also on the time cavity. If you are using a fully synthetic engine oil, you will need to change it even if you haven't run 10,000 kilometers in 1 year.

Because the performance of the engine oil will deteriorate after a long period of use, it will slowly lose its original efficacy, and it will not play a protective role in the vehicle engine.

Therefore, the recommended replacement cycle of engine oil is the point at which its performance begins to deteriorate, and if it is not replaced after this point, of course, it will not immediately have a great impact on the engine, but in the long run, it will shorten the service life of the engine, and it will also cause the performance of the engine.

In addition, the oil change cycle has a lot to do with the state of the vehicle in normal use, if the vehicle usually runs at high speeds, the maintenance cycle can follow the recommendations. If the vehicle is usually driven in a more congested city, often starts and stops, and cannot run, in this case, we recommend that you can shorten some replacements.

And if we want to change the oil, in fact, we don't need to look at the number of kilometers traveled, which has little to do with the number of kilometers, specifically to see what kind of state the oil in our car is, which requires the maintenance master to do a test of the oil, and you can also use a special test strip to check. If it is blackened, it means that it does not play a role and should be replaced in time.

In fact, for the vehicle, it is better to change the oil early than to prolong the change, in addition to economic factors, we still believe that try not to exceed the recommended replacement interval of each oil, so as to protect the vehicle, prolong the service life of the engine and maintain the good condition of the vehicle.

The oil change time depends on the type of engine oil: 1. Fully synthetic engine oil 10,000 km or change once every 1 year; 2. Semi-synthetic engine oil is 7500 kilometers or changed every 7 to 8 months; 3. Mineral engine oil is changed once every 5000 kilometers or 6 months. If the oil is not changed for a long time, the oil will deteriorate and the lubrication effect will be reduced, and the internal parts of the engine will not 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.

Oil identification method: 1. Smell method: take out the oil dipstick and smell it close to your nose, if there is a strong sour smell of return, it means that the oil has deteriorated and should be replaced; 2. Hand twisting method:

Grind the old engine oil with your thumb and index finger repeatedly, if you feel impurities, poor viscosity, or even astringency, you should replace it; 3. Color discrimination method: take a clean white filter test paper, drop a few old engine oil on the limb burning paper, and replace it when it is dark black and brown with impurities after the oil leaks.

There is no fixed cycle for the oil replacement cycle, which is related to many factors such as the car environment, habits, oil types, etc., without considering the influence of factors such as environment and habits, if you want to change the cycle for a long time, you can use fully synthetic engine oil.

Normally, mineral engine oil needs to be replaced for about 5,000 kilometers, semi-synthetic engine oil about 8,000 kilometers, and fully synthetic engine oil about 10,000 kilometers. It is important to note that motor oil also has a shelf life, and it is generally not recommended to change the cycle for more than 18 months. So you can't run thousands of kilometers a year, and you don't necessarily have to use synthetic motor oil.

He won't increase the power of the engine, because no matter what the oil, it only cools and lubricates, and cannot change the engine power.

Hello! Automobile engine oil is generally 5000-10000 kilometers or 1 year, whichever comes first, and it is regularly replaced, which can be referred to the maintenance manual.

Hello, fully synthetic engine oil is generally a year or 10,000 km.

Replace once a yearGenerally, depending on what specifications of engine oil the owner chooses, if you choose a better engine oil, you can change the oil once a year. Of course, some car owners have not driven a few times a month, and this situation can be appropriately extended.

If the owner's car is not driven for a long time, it is recommended to choose fully synthetic engine oil, although the overall cost will be more expensive than the general special oil and semi-synthetic engine oil, but the manufacturing and refining technology of fully synthetic engine oil is high, and the cleanliness, lubrication, viscosity, and sealing performance inside the oil can meet the requirements of long-term non-open parking.

The type of engine oil and the corresponding replacement interval:1. Mineral engine oil: 5000 kilometers or replace once every 3 months;

2. Semi-synthetic engine oil: 7500 kilometers or 6 months to replace;

3. Fully synthetic engine oil: 10,000 kilometers or once a year to replace.

The engine oil is generally changed every 5000 kilometers.

In fact, how often you change your engine oil depends on many factors, including the quality of the oil you use, the environment in the region, the age of the model, and so on. Just like the number of meals you eat each day, it is related to many factors such as the calories of the food you eat, the amount of exercise you exercise that day, and so on.

Generally speaking, the use of mineral oil needs to be changed once within 5000 km, and the longest should not exceed 5000 km. Semi-synthetic oil can extend the oil change interval to 7,500 km, and fully synthetic oil can be extended to 10,000 km to change once. According to different car environment, driving habits and other factors, it can be appropriately extended or shortened.

Precautions for engine oil:

In addition to determining the oil change interval based on the mileage driven, the oil also has an expiration date. Because compared with placing it in the oil drum, the shelf life of the engine oil in the harsh environment of high temperature and high pressure in the engine will be greatly shortened, and the performance will be greatly reduced, and the engine will not be protected over time. Therefore, even if the vehicle has less mileage, it is also necessary to change the oil regularly.

For newly bought cars, the first maintenance can be a little earlier, after all, it is also in the run-in stage of the car, and there are a lot of metal chips in the oil, which is very harmful to the sealing devices, especially the models with turbines. So early maintenance, it must be right.

The maintenance interval of mineral engine oil and semi-synthetic engine oil is one year or 5,000 kilometers, and the maintenance interval of fully synthetic engine oil is one year or 10,000 kilometers, so it is best to use fully synthetic engine oil to maintain the vehicle.

There are three types of engine oil, mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil, add semi-synthetic engine oil to replace once every 5,000 kilometers, add fully synthetic engine oil to replace once after 10,000 kilometers, and change once every six months.

General mineral engine oil new car regulations 5000 kilometers or half a year, semi-synthetic 7500 kilometers or months, fully synthetic oil change time is longer, generally 10000 kilometers or a year, but also according to the vehicle use environment and driving habits. I hope mine can help you.

If it is a fully synthetic engine oil, it will be replaced at about 10,000 kilometers or a year, whichever comes first.

Regarding the replacement cycle and dosage of engine oil, everyone is particularly concerned about the issue, the most direct is to check their own car maintenance manual, which is generally very clearly introduced. But there are also many people's maintenance manuals that have long been missing, so you need to know more about it. Generally speaking, the oil replacement cycle is 5000 kilometers, and the specific replacement cycle and amount should be judged according to the relevant information of the model.

The engine oil is generally changed once every six months or so, and it can be adjusted according to the usage. A good oil can be changed for a longer time.

The maintenance interval of engine oil is theoretically said to be the most suitable to be replaced once every six months or 5,000 kilometers.

However, if the cycle is too short, you can choose a fully synthetic engine oil, so that you can change it once every 10,000 kilometers.

If it helps.

The oil change interval has a great relationship with the quality of the engine oil used and the type of engine oil, which is divided into mineral oil, semi-synthetic engine oil, and fully synthetic engine oil from the perspective of engine oil type. Among them, fully synthetic engine oil is indeed better than mineral oil and semi-synthetic engine oil, with fewer impurities and more stable performance, so the oil change interval is longer is fully synthetic engine oil. As I have always been, the quality of Shell Pioneer Helix Ultra synthetic motor oil can extend the service interval, usually every 10,000 km.

It depends on the type of engine oil, if it is fully synthetic, you can do the first change once a yearThe type of engine oil and the corresponding replacement interval:

1. Mineral engine oil: 5000 kilometers or 3 months to replace one-year-old celery.

2. Semi-synthetic engine oil: 7500 kilometers or 6 months to replace;

3. Fully synthetic engine oil: 10,000 kilometers or once a year to replace.

The role of motor oil.

1. Lubrication and friction reduction: a layer of oil film is formed on the surface of the two sliding parts, so that there will be no friction when the parts are running, and the parts can run smoothly.

2. Clean and dispersed: good engine oil can wash the spoils on the surface of parts and components through the flow of oil, adsorb 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, high temperature is generated, and when the oil reaches the running part, it will absorb the heat, and then take away the heat to assist the parts to dissipate heat.

4. Sealing leakage: It refers to the formation of a sealing ring by oil film between the piston ring and the piston to prevent the exhaust gas after combustion from entering the crankcase.

Summary. 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.

Please wait. 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.

The general fully synthetic engine oil is 10,000 kilometers or 1 year to replace Sun Tuan. 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 will be reduced, and the internal parts of the engine will not be lubricated when the engine is working, which will lead to the wear and tear of the internal parts of the engine and shorten the service life of the engine.
