With so many types and models of vehicle engine oil, how do we choose?

Many car owners know that the vehicle needs to be maintained, and they know that engine oil is very important for the car. However, there are many types and models of engine oil, and at first glance it seems complicated, so you don't know how to choose the right oil for your vehicle.

There are three main categories of motor oils: mineral oils, semi-synthetic motor oils, and fully synthetic motor oils. Mineral oil is the most traditional engine oil, extracted from petroleum, and this oil performance is the worst of the three categories, and now fewer and fewer vehicles use mineral oil.

Synthetic engine oil, which is synthesized artificially in the laboratory, has excellent performance, and was first used in the aerospace field, and then gradually extended to racing cars, and now ordinary vehicles are also using more and more synthetic engine oil. A fully synthetic motor oil means that all the ingredients are synthetic. Fully synthetic motor oil has excellent cooling ability, sealing, oxidation resistance and fluidity, so it is recommended for vehicles with turbocharging, and some vehicles with large displacement self-priming engines are also recommended to use full synthetic motor oil.

Although fully synthetic engine oil is good, it is more expensive, and it is not necessary to use fully synthetic engine oil for all engines. Semi-synthetic engine oil fills the gap between fully synthetic engine oil and mineral oil, it is made of synthetic engine oil and mineral oil mixed in a certain proportion, although the performance is not as good as fully synthetic engine oil, but it is also correspondingly cheaper, and small displacement self-priming engine vehicles can choose semi-synthetic engine oil.

Let's talk about the various types of engine oil. What we commonly see is a number plus W followed by a number like 5W-40 in the form of engine oil labeling. The 5 before W represents the antifreeze index of the engine oil, and the specific value is this number minus 35, and 5W means that the engine oil can ensure the normal start of the vehicle in an environment of minus 30 degrees.

The following number is the viscosity at high temperatures, and the higher the value, the more viscous it becomes. Now we know that we first choose according to the low ambient temperature, and then look at the high temperature viscosity, the viscosity is not the higher the better, but according to the engine's own needs to choose, you can also ask the service consultant.

The above is about the classification and selection of engine oil types and models, we only need to know which engine to choose according to the needs of the vehicle engine itself and the extreme minimum ambient temperature in winter. In addition, it should be added that the replacement cycle of semi-synthetic engine oil is 8 months or 7,500 kilometers, while that of fully synthetic engine oil is 1 year or 10,000 kilometers.

There are so many types of engine oil, how do we choose?

There are two parts to the selection of automobile engine oil model, one is the quality grade API, the other is the viscosity grade SAE, the quality grade API can be selected according to the corresponding level of the engine model, and the more important is the selection of the viscosity grade, which is also relatively complicated.

According to the classification of SAE viscosity grades, there are 6 types of winter engine oils, 5 types of summer engine oils, and 16 types of winter and summer oils.

There are 6 kinds of winter engine oil, which are 0w, 5w, 10w, 15w, 20w, 25w, w means the abbreviation of winter, the smaller the number in front of it, the greater the fluidity of the oil, and the lower the applicable temperature.

There are 5 types of summer engine oil, which are. The higher the number, the higher the viscosity of the oil, the stronger the protection against high temperatures, and the higher the temperature environment can be applied.

There are 16 kinds of common ones in winter and summer, which are 5w w w50.

There are many factors influencing the choice of viscosity label, such as driving environment, driving habits, vehicle model, and so on. For example, German cars are recommended to use a higher viscosity oil, while Japanese cars and Korean cars use a lower viscosity oil, which is due to the internal structure of the engine.

Similarly, for new or high-performance vehicles, the cylinder is better sealed, and low-viscosity oil can be used; For low-grade cars and old cars, a higher viscosity oil is required, because of the engine process and long-term cylinder wear, a high viscosity oil can form a thicker oil film and better protect the engine.

If the driving environment is harsh in winter, such as the weather in northern China, 0w or 5w engine oil is generally used to ensure its smooth cold start and better protection for the engine.

There are 12 grades, and there are 9 grades of diesel engine oil. The second is the classification of viscosity grades, which is classified according to the standards of the Society of Automotive Engineers (SAE), and the specific meanings are as follows:

There are 6 types of winter oils, 4 types of summer oils, and 16 types of winter and summer general oils.

1.The oil grades used in winter are: 0w, 5w, 10w, 15w, 20w, 25w, the symbol w represents winter, the smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature;

2.The higher the number, the greater the viscosity, and the higher the applicable maximum temperature;

3.The general oil grades in winter and summer are: 5w w w w

The label after the classification of the engine oil indicates its viscosity specifications, for example, in "15w w-40", "w" means winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the oil seepage source, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start, such as 5w represents the external low temperature resistance -30 °C, and the 20w low temperature resistance is -15 ° The following digital generation of the cluster meter oil at 100 moving viscosity dust beam, the higher the value, the higher the viscosity. 40 represents 100 degrees Celsius, and the kinematic viscosity standard is between to, which is definitely not what some people say can be used below 40.

Now you know how to choose the right oil for your car. Move your rich hand, and pay attention to me. It is recommended that you choose a fully synthetic engine oil when buying engine oil, which can give better protection to the engine and a longer oil change interval.

<> you have decided what type of oil to choose, the next step is to choose the type of oil that suits your car's engine. For example, I know what the letters and numbers in the engine oil model mean, for example, 0w40 engine oil, w is the abbreviation of winter, winter is the representative of winter, if there is a letter w in the engine oil model, it means that the oil can be used normally in winter. The next number is the viscosity at high temperatures, and the higher the number, the greater the viscosity.

In this way, we know that we should choose according to the low ambient temperature, and then look at the high temperature viscosity, the higher the viscosity, the better, but according to the needs of the engine itself.

The number in front of the w indicates the low-temperature fluidity of the oil, and the number after the w indicates the high-temperature viscosity. 0w means that the oil can flow normally at minus 35 degrees, 5w means that the oil can flow normally at minus 30 degrees, and 10w means that the oil can flow normally at minus 25 degrees. Semi-synthetic oil is a mixture of wild Zen synthetic oil and mineral oil in a certain ratio.

Although its performance is not as good as that of fully synthetic oil, it is also correspondingly cheaper. Vehicles with self-priming engines with small displacements can opt for semi-synthetic oils, thus bridging the gap between fully synthetic and mineral oils.

It can be divided into mineral oil, semi-synthetic engine oil, and fully synthetic engine oil. Generally speaking, it can only be divided into these three categories, and our more common ** and cheaper ones are mineral oil. It is necessary to choose the right engine oil according to our own acceptable ** range, and then according to the quality of our own car.

If your car is cheaper, you can choose regular mineral oil.

It can be divided into fully synthetic engine oil, semi-synthetic engine oil, and mineral engine oil, you should choose the right type according to the engine model of the car, pay attention to the mineral oil is easy to oxidize, and then do not change the oil frequently, you should also pay attention to the viscosity of the oil, for example, mineral oil is generally more viscous, which is directly contained or extracted from minerals.

Fully synthetic motor oil, mineral oil, semi-synthetic motor oil, which is mainly classified according to the extracted square wheel tremor method. It is best to choose a fully synthetic engine oil, this kind of engine oil is relatively expensive, but it can protect the engine well, and the lubrication effect is very good.

There are three types of automobile engine oil: mineral oil, semi-integrated engine oil and fully synthetic engine oil; Fully synthetic engine oil has the best protection for the engine, and the lubricating fluid is very good, so it is recommended to choose a fully synthetic engine oil, but the price will be more expensive for the first money.

At present, there are three main types of automotive engine oils: mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil. We all know that the engine is like the human heart and plays a very important role in the car, while the engine oil is like the blood of the human body.

The inside of the engine has been lubricated to ensure the normal output of the engine, so many customers do not know about the engine oil and do not know how to choose. So today we will talk about the three most common engine oils on the market: mineral engine oilMineral engine oil is a lubricant extracted from petroleum, and the base oil of mineral oil is the product of refining the remaining base oil into useful light substances (such as aviation oil, gasoline, etc.).

In the refining process, by its very nature, mineral oil uses inferior ingredients in the oil. Mineral oil is the most common type of lubricant on the market today. Although mineral oil** is low, its service life and lubricating properties are not as good as semi-refined oil and synthetic oil.

Semi-synthetic engine oilSemi-synthetic engine oil is a kind of lubricating oil refined by hydrofission technology on the basis of mineral oil with international base oil as raw material. Specifically, it is made by mixing mineral oil and synthetic oil in a ratio of 4:6 and adding some additives.

Fully Synthetic Motor OilFully synthetic motor oil is the premium oil among motor oils. It is a lubricating liquid composed of macromolecules composed of ethylene and propylene dispersed in gas or gas, and then refined by complex chemical reactions such as polymerization and catalysis. Essentially, it is to use the best components to achieve the expected molecular form through chemical reaction and artificial control.

The silver balance molecules of fully synthetic oil are neatly arranged, and the ability to resist external variables is naturally very strong, so the physical constitution is good, and the thermal stability, antioxidant reaction, and viscosity change resistance are naturally much stronger than mineral oil and semi-synthetic oil. Although there are three main types of common motor oils, each has a different grade and viscosity. It is advisable to check your own factory maintenance manual.

Finally, I would like to remind you that about 10 models without turbo pressure should use semi-synthetic engine oil, and more than 200,000 models with turbocharging should use fully synthetic engine oil as much as possible, which is good for engine performance and can also reduce internal wear and tear of the engine.

There are two parts of the selection of vehicle oil model specifications, one is the quality grade API, the other is the viscosity grade SAE, the quality grade API can be selected according to the corresponding grade of the engine model, the main one is the selection of the viscosity level, which is also correspondingly more complicated.

According to the classification of SAE viscosity grades, there are 6 types of engine oils in winter, 5 types of engine oils in summer, and 16 types of universal oil in winter and summer.

There are 6 kinds of winter engine oil, which are 0w, 5w, mausoleum or 10w, 15w, 20w, 25w, w indicates the abbreviation of winter winter, the smaller the data in front of it, the greater the circulation of the oil, and the lower the available temperature.

There are 5 types of summer engine oil, for . The higher the data, the higher the viscosity of the oil, the stronger the high maintenance characteristics, and the higher the temperature natural environment can be used.

There are 16 types of winter and summer universality, each of which is 5w w w w50.

There are many factors influencing the selection of viscosity models, such as safe driving, natural environment, driving habits, and vehicle series. For example, German cars are proposed to use higher viscosity oil, while Japanese cars and Korean cars use lower viscosity oil, which is also due to the internal structure of the car engine.

Similarly, for new cars or cars with excellent performance, the cylinder has good airtightness, and low-viscosity engine oil can be applied; For low-grade cars and old cars, it is necessary to choose a higher viscosity engine oil, due to the automobile engine processing technology and long-term cylinder damage, the high viscosity engine oil can produce a thick slick oil, stronger maintenance of the car engine.

If the conditions in the natural environment are more extreme in winter, such as the weather in the north of our country, the engine oil of 0w or 5w is generally used to ensure that its cold start is smooth and the car engine has stronger air inspection and maintenance.
