What is the significance of choosing to change fully synthetic motor oil for car maintenance below 1

Changing to high-quality oil makes the vehicle feel better to drive, so it makes perfect sense. I regret that I changed the GT Magic Red oil too late, the power is much stronger than the original oil, and the throttle is found to be amazing, and the rapid acceleration is super powerful. The long replacement cycle of 15,000 kilometers of PAO engine oil is also a great highlight, which saves several maintenance times compared with the original engine oil in a year, and then the power decline period is 10,000 kilometers.

The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life, so what requirements should qualified lubricating oil meet? In other words, what are the six functions of lubricating oil?

1. Lubrication and wear reduction: between the piston and the cylinder, between the spindle and the bearing, there is a fast relative sliding, to prevent the parts from wearing too quickly, it is necessary to establish an oil film between the two sliding surfaces. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

2. Cooling and cooling: The oil can bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine.

3. Cleaning and cleaning: good engine oil can bring carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash the dirt generated on the working surface of the parts through the flow of lubricating oil.

4. Sealing and leak-proof: The oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering.

5. Anti-rust and anti-corrosion: lubricating oil can be absorbed on the surface of parts to prevent water, air, acidic substances and harmful gases from contacting parts.

6. Shock absorption and buffering: when the pressure of the engine cylinder port rises sharply, the load on the piston, piston chips, connecting rod and crankshaft bearing is suddenly aggravated, and the load is transmitted and lubricated by the bearing, so that the impact load bears plays a buffering role.

Classification of motor oil:

At present, the engine oil on the market can be simply divided into two types: mineral oil and synthetic oil due to the difference in base oil (vegetable oil is not counted due to the scarcity of production). Synthetic oil is divided into: fully synthetic and semi-synthetic. Fully synthetic motor oil is of the highest grade.

The biggest difference between the two is that synthetic oil can be used at a wider temperature, with a longer service life and higher cost; The same oil film requirements can be achieved with a lower viscosity of synthetic oil, while mineral oil needs to be more dense than synthetic oil to achieve this requirement. In the same working environment, synthetic oil is more expensive because it has a much longer service life than mineral oil, but after comparing the number of oil changes, it is not much higher than mineral oil.

Hope it helps.

Hello, fully synthetic engine oil is good for the performance of the engine, and the mileage is long, and it can generally be used for maintenance of 8500-10000 kilometers.

There is no need, just use good oil without bad money.

There is no need to use fully synthetic engine oil for car maintenance and oil change, for the following reasons:(1) The composition of fully synthetic engine oil is good, but it is not suitable for all vehicles; (2) The advantages of fully synthetic motor oils are exaggerated.

Uses of motor oil

Cars rely on gasoline to run, but the importance of motor oil is also self-evidentIt can play a role in the car to protect the parts caused by the friction of the internal metals; Externally, when the internal parts of the car are in a high temperature state, the engine oil can also take away part of the heat and play the role of a cooling system; In addition, the engine oil can also take away the metal chips that peel off the internal parts of the car, which plays a role in scouring and cleaning.

Fully synthetic motor oil is not suitable for all vehicles

Due to the different compositions of engine oil, it can be divided into three types: fully synthetic engine oil, semi-synthetic engine oil, and mineral engine oil. Of the three oils, fully synthetic motor oils are of higher quality and** more expensive. The quality of fully synthetic motor oil is high, but it is not suitable for all models, and for general A-class cars, or cars with a less delicate engine, fully synthetic motor oil does not exert its own stability and lubrication effect, so it is completely unnecessary.

For cars that are generally less than 150,000 yuan, semi-synthetic engine oil plays the same role as fully synthetic engine oil.

The advantages of fully synthetic motor oils are exaggerated

No matter what the price of the model, when you come to the 4S shop or repair shop for maintenance,The clerk will always recommend us a higher quality fully synthetic motor oil, which inevitably exaggerates the advantages of fully synthetic motor oil and has the possibility of making greater profits. As for what kind of oil to choose for maintenance of a car, you can choose according to the suggestions in your car's car maintenance manual.

Car maintenance has a lot of knowledge, good engine oil is like fine food, the quality is good but not suitable for everyone, if the stomach can not adapt, not only can not absorb higher nutrients, but will cause gastrointestinal disorders, bring unnecessary trouble. Car maintenance should still be chosen according to the condition of the car.

It is necessary, just like a person eating, eating well, the body will be healthier, the lubricity of fully synthetic engine oil will be better, compared with mineral oil, it is cleaner, better for the engine, you can run many kilometers and then do maintenance, reduce fuel consumption.

There is no need to use fully synthetic engine oil for car maintenance and oil change, because synthetic engine oil has very high requirements for the engine of the car, and ordinary engines will damage the engine if synthetic engine oil is used.

Although fully synthetic motor oil is the highest quality, it is not suitable for all cars, and some ** cheap cars do not need to use such a good opportunity. If your car** is less than 150,000, you can consider semi-synthetic engine oil when choosing engine oil.

Some are not necessary, although the fully synthetic engine oil is the highest quality, but it is not suitable for all cars, and some ** cheap cars do not need to use such a good opportunity.

Look how you open it. If your car is like a taxi, you have to run two or three hundred kilometers every day, and if you insist on changing it every five or six thousand kilometers, you will have no problem using mineral oil. If you drive less, less than 10,000 kilometers a year, then it must be fully synthetic.

<><For car maintenance below 200,000, can't you use Quanhezhao to infiltrate into engine oil?

In the maintenance project of the car, the engine oil is a very conventional maintenance item, generally speaking, the oil is changed once and it is replaced after running 5000 kilometers.

I have to use the car every day, and I need to maintain it about 3 times a year, and there are no other failures, and the cost of each time is about 500. It's just that 5000 kilometers to change engine oil refers to mineral engine oil, and fully synthetic engine oil can be driven to the spine of 10,000 people, but its ** is more expensive, and ordinary cars will not consider it. It is even said on the Internet that fully synthetic engine oil cannot be used for car maintenance below 200,000 yuan, is this based on the theory that "cheap cars can't use good engine oil"?

The reason why fully synthetic engine oil is expensive is that it has a long service life, which can be driven to 10,000 kilometers after one replacement, and can be used for a little longer if it is a naturally aspirated engine.

Other cheap engine oils are changed more frequently, which is about the same as fully synthetic engine oil, and this oil has strong fluidity, which means that its cleaning ability, lubricity, and oxidation resistance are better.

As for cars below 200,000 yuan, fully synthetic engine oil is not suitable because among the types of engine oil recommended by manufacturers, cheaper mineral engine oil is also recommended. Therefore, some people think that it is a waste to use such good engine oil for a cheap car, and the internal structure of the engine is not so fine, and it is not of much use to use it well, which is actually a fallacy.

The reason why manufacturers recommend cheap cars is also to consider the travel cost of car owners.

If you have enough economic budget, you will definitely choose a better car, so the recommended maintenance plan is that there is no damage to the car and you can consider it for the owner. As for the owner himself, he can choose the type of engine oil independently, mineral engine oil, semi-synthetic engine oil, and fully synthetic engine oil can be used, that is, the service life of each is different, ** is different, there is no way to say it.

<><Car maintenance really can't use fully synthetic engine oil

As a mechanical product, the car is not driven for a long time or has been driven will bring certain damage to the auto parts, and in order to reduce the consequences of these injuries, it is necessary to maintain the car regularly.

As the core part of the car, the engine is the most powerful part of the car, and its quality directly affects the life of the car, so its maintenance is essential. Regularly replacing gasoline is a way to maintain the engine, and when the car is under 200,000 for maintenance, you really can't use fully synthetic engine oil?

On this issue, experienced old drivers gave their own views, about 200,000 models below can not use fully synthetic engine oil, most of the car talk about the owner of the ant are agreed, they have this perception of three main reasons, the first is that the full synthetic engine oil is too expensive, it is not cost-effective to use.

The ** of fully synthetic engine oil is indeed much higher than that of ordinary engine oil, which is in the specific use of the buried process, mineral oil and semi-synthetic engine oil must be replaced every 5000 kilometers, while the fully synthetic engine oil is replaced once in 10000 kilometers, and for a long time, the additional costs such as labor hours required for the replacement of mineral oil and semi-synthetic engine oil are also similar to those of fully synthetic engine oil, but it is not as good as fully synthetic engine oil.

The second is that most people think that cheap models have large gaps between parts, and if you use fully synthetic engine oil, it will leak into the combustion chamber. As for the viscosity of the engine oil, as long as the SAE level is the same, the viscosity of the engine oil is the same, and it has nothing to do with the type of engine oil.

As for the poor car does not use the accuracy is not good, this sentence is not true, as far as Qingchen knows, the robots used in the production line of domestic and joint venture cars are all from Sweden's ABB, Germany's Dürr and Japan's Fanuc, and there is no difference in accuracy between them.

In the end, many people feel that the manufacturer's advice is the best, and many models recommend the use of mineral oil in the manual, and most car owners accept this advice. What Qingchen wants to say is that the manufacturer's recommendation represents only the lowest standard, as long as you are above this minimum standard, the car will have problems, and the manufacturer should also consider the cost when making recommendations.

If the suggestion is too high, consumers will definitely not accept it, so from the above situation, it is not that models below 200,000 can not use fully synthetic engine oil, any model can be used, and the reason for this perception is that everyone is caused by false rumors.

Fully synthetic engine oil for car maintenance is good.

Fully synthetic motor oils offer the following advantages over semi-synthetic motor oils:

1. Fully synthetic engine oil has better high and low temperature performance. Fully synthetic oils are used at a wider temperature and have a longer service life; The same oil film requirements can be achieved with a lower viscosity of synthetic oils, while semi-synthetic oils need to use a higher viscosity than synthetic oils to achieve such requirements. In other words, in the same operating environment, a fully synthetic oil can protect the engine with a lower viscosity.

2. There is a longer oil change interval. Synthetic oils are more oxidation resistant, greatly extending oil change intervals, and reducing the number of oil and filter changes, although the oil input is increased. In general, engine oil change intervals with fully synthetic engine oil can be extended to 7,500-10,000 km.

From the point of view, in 4S shops or fast repair shops, a barrel of conventional 4L mineral engine oil** is mostly 150-200 yuan, semi-synthetic is 250-300 yuan, and fully synthetic is about 350 yuan. Combined with the oil change interval, fully synthetic engine oil is more cost-effective.

3. Suitable for worse vehicle conditions. Synthetic oil is suitable for higher load engines, and also has stronger resistance to high temperature and shear, and the oil will not lose viscosity under high-speed engine operation, and the protection of the engine is more comprehensive. Synthetic motor oil is of good quality and will be noticeable in the following aspects:

Smoother cold starts, especially in the Tohoku region, are more fuel-efficient.

The quality of fully synthetic motor oils is definitely better than that of semi-synthetic motor oils and mineral oils. Its lubrication effect, cleaning and dispersion, oxidation resistance and anti-attenuation ability are better than those of the other two types of engine oils. The oil drain interval is also longer than the other two types of oil.

Engines with large displacement or turbochargers are recommended to use fully synthetic oils. Better protection of the engine and turbocharger. If it is an ordinary family car with a small displacement, there is no special requirement in the manual.

You can choose between semi-synthetic motor oil or mineral oil. However, choosing these two types of motor oils requires a corresponding reduction in service intervals and mileage.

This is based on the performance of your engine, and if your engine requires a fully synthetic one, you must use a fully synthetic one.
