Does your car s oil need to be changed frequently? Why?

The main reasons why oil will gradually deteriorate during operation are:

Combustion by-products: such as moisture, acids, soot, carbon deposits, etc.;

fuel dilution; high-temperature oxidative deterioration of the oil itself;

Dust and metal particles.

These substances are contained in the oil, and the additives in the oil are constantly depleted as they are used. Failure to change the oil on time will significantly reduce the protective effect of the oil on the anti-wear of the engine. Changing the oil not only removes contaminants from the oil, but also ensures that the components in the oil are kept at a reasonable level.

The oil of the car needs to be changed frequently in order to maintain the balance of the car's oil quantity.

There is no need to change it often, as long as the car is not faulty, there is no need to change the oil frequently, you can change it when you maintain the car, and there is no need to worry about this problem.

There is no need to replace it often, just change it once a year to two years, and if you replace it frequently, it will cause some damage to the car.

Yes, because changing the engine oil frequently, in fact, it is also conducive to the maintenance of the car's engine, and it also plays a role in the maintenance of the engine.

For car oil change maintenance, many car owners change the oil according to the periodic table provided by the car manufacturer and change the oil in the repair plant of the 4S shop. So, why do you need to change your engine oil regularly?

The importance of oil changes.

Engine oil is to the engine what blood is to the heart. Engine oil contains a variety of additives, which can effectively protect the important moving parts of the engine and ensure the normal operation of the engine.

Lubrication: The main function of engine oil is lubrication, which can form an oil film on the surface of the metal parts of the engine and reduce the wear of the metal surface.

Cleaning: Decomposes the sludge and deposits generated during the use of the engine to keep the inside of the engine clean.

Anti-rust: neutralize the acidified substances generated during use in the engine, and form an anti-rust and anti-corrosion layer to avoid rust and corrosion of metal parts due to oxidation.

Sealing: Seal the gap between the piston and the cylinder block to make the fuel burn fully and improve the fuel efficiency.

Cooling: Disperses the high temperatures caused by engine wear and protects engine components.

In the process of lubricating oil, additives are gradually consumed, and the pollutants produced by combustion are mixed with the engine oil to produce sludge and deposition, which will not only accelerate engine wear and tear over time, but also lead to serious consequences such as engine rust and corrosion, poor heat dissipation, etc. Therefore, changing the engine oil in time is the best care for the engine.

The interval between oil changes.

When buying a car, the car manufacturer will come with a car maintenance manual, which lists the vehicle's oil change mileage, that is, the oil change interval, most of the cars are 5000-10000 kilometers. Generally, the oil should be changed when the specified oil change mileage is reached, and some high-end vehicles, when the oil change mileage is reached, there will be an oil change prompt in the car.

In actual driving, road conditions, vehicle conditions, and oil quality will affect the oil change interval. If you drive in the city for a long time, the car stops and starts frequently, which will aggravate engine wear and accelerate oil pollution, so it is necessary to shorten the oil change interval.

The owner can regularly test the oil condition of the car, dipstick a little oil on the finger, if the oil is black, very thin, and contains gravel, it means that the oil has deteriorated at this time, and must be replaced immediately.

Change the oil and change the three filters.

The function of the filter is to filter all kinds of impurities in the oil to prevent impurities from causing wear to the engine, such as not replacing the filter for a long time, the filter will be partially blocked due to dirt, and the pollutants will flow directly into the engine, aggravating the wear of the parts; If only the oil is changed without changing the filter, the contaminated oil remaining in the old filter will re-enter the oil circulation, so experts emphasize: the filter should be replaced every time the oil is changed.

In addition to the regular replacement of the filter, the gasoline filter (air filter) and air filter (air filter) must be replaced regularly, and the general replacement standard is to replace the air filter every 20,000 kilometers and the air filter every 10,000 kilometers.

Many friends who have just bought a car may think that the role of engine oil is only lubrication, which is not true. When added to the engine, engine oil plays five major roles.

The first is lubrication: oil enters the valve and camshaft, cylinder and piston, crankshaft and bearing and other metals to form an oil film to reduce friction and make the operation balanced.

The second is sealing: the oil fills the gap between the cylinder and the piston, preventing the leakage of compressed gas and gas from the combustion chamber of the engine, so as to give full play to the power of the engine.

The third is cooling: the oil absorbs the heat generated by the engine when it is running at high speed, preventing expansion and sintering due to overheating.

The fourth is cleaning and dispersion: the e-liquid and insoluble components produced during combustion hinder the normal operation of the engine, and the oil absorbs these dirt to make the engine clean.

The fifth is anti-rust effect: the engine oil will adhere to the metal surface inside the engine, and has the effect of a surface coating agent that prevents rust and corrosion on the metal surface.

Engine oil has these five functions, which is enough to prove its importance in the driving of the car. So, that's why every time we go for maintenance, the repairman will check the oil in the engine first.

In addition, a good engine oil will keep your car running for years with its engine as clean and running as good as new.

Engine oil can help car parts work efficiently and can also effectively reduce the heat energy generated when the engine is working. Secondly, the oil reduces the build-up of carbon deposits and varnish on the engine, which protects the engine in addition to reducing heat. Finally, motor oil acts as a lubricant that helps the engine perform several functions.

Therefore, whether the car can run smoothly depends on the engine oil, which is the main purpose of oil change.

Hello Generally, we understand this problem in this way - 1 - after a certain mileage, the air filter is polluted, and the air enters the engine, which produces a certain amount of pollution to the oil; 2--The working temperature of the engine aggravates the oxidation of the engine oil, and the engine oil no longer has the role of good lubrication and protection of the friction pair as new; 3--The oil has been mixed with some impurities, which is not clean, accelerated, and the crankshaft and bearing pads are worn; 4--If the engine oil that has been used for a long time is not changed in time, it is easy to produce carbon deposits and sludge inside the engine.

Engine oil can dissipate heat and lubricate the engine, and if it is not replaced regularly, it will lead to premature wear of the engine and affect the service life of the engine.

Actually, this question. Engine oil is the enterprise and its lubricating effect. If it's extremely worn for a long time, there's some iron foam or something in it.

The oil is not very clean, so if you use an iron trowel to wipe the machine, the aging degree of such a machine should be faster, so you should change the oil in time. It can better protect the machine.

Because if the car is cold for a long time, then it will slowly age in it, and the damage to the car is very great, so it is necessary to change the teaching materials regularly to be safe enough.

Why should cars change their oil regularly? Because the oil runs to a certain number of kilometers, it needs to be replaced, otherwise the safety factor is not high.

The car runs 5000 kilometers, or well, how many distances do you have to change the oil regularly? This helps the machine to run more and avoids wear and tear.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

<> today's automobiles, the general requirement is 5,000 kilometers or half a year to change the oil and maintain. Some well-known brands stipulate that within 3,000 kilometers in 2 months, and some need to be within 7,500 kilometers within 6 months. According to the classification of the model, under normal conditions, Japanese cars must change the engine oil for 3 months or 5,000 kilometers; European and American cars must change the engine oil for 1 year or more than 10,000 kilometers.

Therefore, it is necessary to change the engine oil or follow the maintenance manual.

There is also a common misconception that must be elaborated, that is, whether the engine oil needs to be replaced if it is blackened? It should be said that such views are not comprehensive. If the car engine grease is not added with a static thickener, then the blackening indicates that the refined oil has already been seriously mildewed.

However, today's motor oils are generally infused with quiet thickeners, so this is no longer the case.

This is also because the lubricant of today's automobiles is generally added with a quiet solvent, which cleans out the adhesive tape and carbon deposits adhered to the piston rod and disperses them in the oil to reduce the conversion of high temperature precipitation in the automobile engine, so the color of the grease needs to be black after a period of application, but the oil at this time is not completely mildew.

Nowadays, the vast majority of private car owners have already replaced their vehicles before they have been transferred to more than 200,000 kilometers. Therefore, the result of washing the engine oil is basically to spend a lot of money to return to the natural environment to produce work pressure, and the engine oil released should be used first-class, and it cannot be discharged casually. "Diligence" or "not diligence" is the relative definition, the appropriate scientific research is good, even if some is money, some is time, don't waste it, just like the kind of your own car, carry us to see the splendid rivers and mountains, the world of rivers and lakes, wouldn't it be happy?

The main reason is that the automobile engine must have a kind of integration and running-in period for each oil that has just been changed, which is generally the most beneficial to the moisturizing and deheating of the automobile engine above 100 kilometers. Therefore, if the oil is changed frequently, there is no way to achieve the effect, so the oil should be replaced in accordance with the rules and norms, rather than every once in a while.

It must be noted here that generally speaking, after 5 minutes of driving, the color of the oil will change from golden yellow to dark yellow, and after 500 kilometers, the color of the oil will be completely black. This, in turn, is likely to indicate that the oil is actually cleaning up well. Generally, when the oil has just been changed at 5000 kilometers, it will be the best to clean the actual effect.

Naturally, how often you change the oil is actually related to your attitude towards the car. If you are very concerned about the car in front of you and are not ready to replace it in ten years, you can change the oil in the above way, if you want to sell it after two years, then it doesn't matter if you postpone it. However, in view of the problem of whether to change the engine oil frequently, it is not so much as searching for some unreliable maintenance methods on the Internet to destroy the car, it is better to take a good look at your maintenance manual, change the engine oil in a reliable area according to the above requirements, and do maintenance to ensure that your own car is running normally.

The oil of the car does not need to be changed frequently, and if it is changed frequently, it is likely to cause problems in the car, which is not conducive to the service life of the car.

No, just change the oil regularly, as frequent oil changes can lead to damage to the engine and can also affect the parts of the car.

It doesn't need to be replaced frequently, it can be replaced every two to three years to get a good drive, and you can also maintain the car.

After buying a car, changing the engine oil is a must for car maintenance, because the oil contains a variety of additives that can protect the normal operation of the engine. Therefore, it needs to be regularly maintained and replaced, so why should the car change the oil blade?

1. The engine oil itself plays a role in lubricating the engine, if the owner does not change the oil, it will easily lead to ineffective and deterioration of the oil, the degree of wear and tear on the engine will increase, and the engine will pull the cylinder if the situation is serious.

2. The engine oil also plays a cleaning role in the engine, if the oil is not changed for a long time, there is a problem, and the impurities generated on the surface of the parts can not be effectively cleaned up, which will affect the heat dissipation function of the engine in the long run, and if the situation is serious, it will also cause the oil channel to be blocked.

3. The cooling effect of the engine oil will be reduced, especially for the parts with weak automobile structure, which are prone to damage in the long run, and there is a possibility of burning.
