How often is it better to change the oil? Is there any harm in not replacing it for too long?

It is better to change the oil every 6 or 12 months. If you don't replace it for too long, it will affect the normal operation of the engineCarbon depositsIncrease, and in severe cases, cause engine failure.

How often to change the engine oil is better, depending on the quality of the oil, if it is just an ordinary mineral machine should be replaced every 6 months, so as to ensure that the oil has good performance, if it is a fully synthetic oil, it can be replaced every 12 months, so as to ensure the quality of the oil and the normal operation of the engine. The oil replacement cycle can also be determined according to the mileage of the car, the mineral oil should be replaced in time after the car has traveled 5,000 kilometers, and the fully synthetic engine oil should be replaced in time after the car has traveled 10,000 kilometers.

When judging whether the car needs to change the oil, it can also be based on the car engine.

If the oil in the engine of the car has deteriorated and deteriorated and the performance has deteriorated, it is necessary to replace the new oil in time, otherwise the engine function will be damaged. The oil in the engine has a variety of functions such as sealing and cooling, lubrication, and cleaning, and if the oil is not changed on time, it will reduce these effects, and the car engine and many parts will be damaged.

If you don't change the oil for too long, the harm to the car engine is extremely obvious, because the high-quality engine oil has a good viscosity, which can block the gap between the cylinder block and the piston and prevent gas leakage, but if you don't change the oil for a long time, the oil will lose its sealing performance, and then the cylinder will leak. If the oil is not changed for a long time, it will also lead to a decrease in the cooling performance of the oil, and when it deteriorates severely, the heat dissipation function of the engine will be greatly reduced, and it is easy to fail due to high engine temperature.

High-quality engine oil has good lubricating properties, if you do not change the oil for a long time, the lubrication performance of the oil will decrease, which will make the gears and shafts and other parts can not work smoothly, and abnormal wear will occur. If you do not change the oil for a long time, the cleaning performance of the oil will decrease, because the metal parts will produce some debris when working, if these debris are not removed in time, it will lead to a large number of carbon impurities in the engine, which will cause harm to the engine, easy to make the engine fail frequently, and will also shorten the service life of the engine.

I think it's best to change the engine once a year or so, if you don't change the oil for a long time, the impurities in the oil will cause the engine to wear and tear aggravated.

The oil needs to be replaced after 8,000 kilometers or a year, and it may deteriorate if it is not returned for a long time, so that the lubrication coefficient will decrease and the engine will wear and tear will increase.

It should be changed every 50,000 km. If you don't change it, it will affect the performance of the engine and cause the car to be particularly fuel-intensive.

Change it every three months. There is a thing, if the oil is not changed, then the car will break down and the service life of the car will be shortened.

It should be replaced once every six months, and there will definitely be something wrong if you don't change it, there will be certain problems, there will be potential safety hazards, and it will affect the life of the car.

<> "How often should I change the engine oil so that it doesn't hurt the car?"

Should I change the engine oil after 5000 km? What is the best service interval? Now, according to the requirements of this OEM and automobile manufacturers, most of the standards and specifications stipulated by this are these six months, or this 5,000 kilometers, so is this standard reasonable?

It should be said that it is relatively reasonable from the perspective of car safety and car maintenance standards.

It should be out of consideration for the protection of the engine and the safety of our car, right? It stipulates a relatively safe oil change interval and oil change mileage, which should be from the maintenance and a requirement of our current engine, it should be said that according to the different models of the engine and the oil and maintenance we use, the quality of this wearing part is different, and the oil change cycle will be different, right?

If you say that everyone uses this ordinary mineral oil, because it itself belongs to a relatively basic maintenance oil, right? It should be said that this 5000 kilometers should be more reasonable, then if we use a higher grade and higher and better grade oil, if we use a fully synthetic or semi-synthetic oil, it should be said that we should extend the maintenance cycle appropriately.

This kind of engine oil itself, its oxidation resistance, lubrication, including some parameters and indices will be relatively high, then it should be said that the speed of attenuation of its oil performance will also slow down, so if we say that we will replace it at 5000 kilometers, it should be said that there will be some waste from an economic point of view, so what about this suggestion?

If you say that you semi-synthetic engine oil, your oil change cycle can be increased to 7,000 kilometers to 8,000 kilometers, if you use this fully synthetic engine oil, you can travel up to 10,000 kilometers to change the oil, then there is no problem with the maintenance and driving safety of your engine, it should be in the mature automobile market, right? Should Kieson say that the oil change interval or should it be said that it is in the range of 7,000 to 10,000 kilometers?

The standard that we regret Xun should pass in China, most of the automobile host manufacturers are implementing 5000 kilometers, and there is no problem with this, but it should be said that from the perspective of car maintenance and car use, it may be said that it will increase the cost and expense of some car maintenance, and we can choose according to the specific situation of our own vehicles and the efficiency and frequency of a specific use of our own cars.

It is better to replace the mineral engine oil once in about 5000 kilometers, the semi-synthetic engine oil in about 7000 kilometers is appropriate, and the service life of the fully synthetic engine oil is longer, which can be replaced once in about 10,000 kilometers. The oil change should also be determined according to the driving environment and driving habits, if the car environment is relatively bad, you can appropriately shorten about 500 kilometers to change the oil.

Now many families are in order to meet their daily needs, buy a car, the maintenance of the car is also the top priority, the car needs different oil, many people in the maintenance of the 4S shop will also recommend the full synthetic oil, and require 5000 kilometers to replace once, this is also a means of 4S shop to make money, we should also determine the different replacement time according to the different oil.

How often should the oil be changed

Different types of engine oil replacement time is different, our common engine oil in life is roughly divided into three categories, namely mineral oil, semi-synthetic oil and fully synthetic oil Generally speaking, mineral oil is about 5000 kilometers, you need to replace a semi-synthetic oil needs to be replaced at about 7000 kilometers, and fully synthetic oil needs to be replaced at about 10,000 kilometers. In this way, the normal use of the engine oil can be ensured.

What else to pay attention to when changing the oil?

As we all know, the main role of oil is to lubricate and dissipate heat, if the oil filter is not replaced for a long time, it will also cause poor lubrication and heat dissipation. In the process of driving the vehicle, we must develop good driving habits to avoid the behavior of stepping on the accelerator to the end, which can better protect the engine.

It is better to change the engine oil about once a year; It is necessary to pay attention to the quality of the engine oil, be sure to add engine oil according to the needs of the engine, be sure to preheat before adding engine oil, change the filter after changing the engine oil, and choose the engine oil according to your driving habits.

I think it can be replaced after 5000 km; Pay attention to the type of oil, avoid the temperature being too high, check it regularly, and change the filter element of the oil.

6 months or 5000 km. When changing engine oil, pay attention to choosing a good quality engine oil.

How long does it take for oil to deteriorate If the oil is not used in the oil pan of the engine, it will deteriorate in 6 to 8 months. Therefore, it is recommended that everyone change the engine oil regularly. Engine oil is called the blood of the engine, and if there is no oil in the engine, the engine cannot function properly.

Engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention, and heat dissipation.

When the engine is running, the oil forms a film on the surface of the various parts in the engine, which prevents the friction caused by direct contact between the various parts in the engine.

If the various parts in the engine are in direct contact to produce friction, it will exacerbate the wear of the engine and also cause the engine to overheat.

If the engine is running in an overheated state, it can cause serious damage to the engine. Zhengqing.

The performance of the engine oil will be reduced after a long period of use, so the engine oil needs to be changed regularly.

When using the car, be sure to change the oil regularly, and change the oil filter element every time you change the oil.

The oil filter is used to filter the oil, and if there is no oil filter, the oil will become dirty after a period of use.

When buying engine oil and oil filter cartridges, be sure to choose the best products from big brands, and be sure to buy them from regular channels.

When you usually use the car, you must maintain your car on time, and regular maintenance can keep the car in good condition.

How often should you change your oil?

It is best to change the engine oil once every 5000 kilometers or so. Engine oil is the lubricating oil for the internal components of the engine, in addition to cooling the engine, can absorb the heat generated by the engine combustion chamber and the top of the piston, and can also be used as a cylinder sealant to fill the gap between the piston and the cylinder wall.

According to the different chemical composition of the oil, the oil can be divided into: mineral oil, semi-synthetic oil and fully synthetic oil, ordinary mineral oil is best changed every 3500-4000 km; Semi-synthetic engine oil can be changed once in 5500-6000 kilometers; Fully synthetic engine oil can be changed once every 7500-8000 km.

Generally, it is best to change the oil and oil filter element once every 5000 kilometers or half a year. For example, if your car has only been driven for three months and the mileage has reached 5,000 kilometers, then you should go for maintenance and change the oil in time, and if the mileage does not reach 5,000 kilometers within half a year, you should also change the engine oil, because the engine oil also has a shelf life. Before you do it.

When a new car travels to 3000 kilometers, it is best to change the oil once and do the first insurance. According to different car environment, driving habits and other factors, it can be appropriately extended or shortened. When changing the oil, it must be replaced together with the oil filter element, only change the oil without changing the oil filter element, just like the effect of not changing the oil, the oil filter element on the market is very cheap, the general ordinary model filter is below 15 yuan, the mid-range car is between 15-35 yuan, and the high-end model is about 50 yuan.

No.

Theoretically speaking, the fully synthetic engine oil needs to be replaced once when the mileage reaches 10,000 kilometers or is used for about a year, because the oil is not changed for a year, and the oil is used for too long, which will lead to the reduction of cooling, sealing, cleaning and lubrication, and contains a large number of metal chips and gels, which affects the stable operation and life of the engine, so it is necessary to change it once a year.

The fully synthetic oil molecules are neatly arranged, with stronger ability to resist external variables, better thermal stability, oxidation resistance, viscosity change resistance, wider application temperature, and better high and low temperature resistance. Compared with the same oil film requirements, the usable viscosity of fully synthetic motor oil is lower, which can achieve the effect of protecting the engine and has better stability and dryness.

Difference Between Semi-Synthetic and Fully Synthetic Motor Oil:

1. The base oil is different: the semi-synthetic engine oil uses the third type of base oil; Fully synthetic motor oil is used.

Class III, IV and V base oils are blended.

2. Different applicable temperatures: the temperature used in fully synthetic oil is more suitable than that of semi-synthetic engine oil.

3. Applicable vehicle conditions are different: semi-synthetic engine oil is mostly used in economical models with small displacement and smooth driving; Fully synthetic motor oils are mostly used in harsh conditions.
