Do you know that the more viscous the oil lasts?

Some car owners think that the viscosity of the engine oil will continue to decrease with the use of time, so they think that the higher the viscosity of the engine oil, the longer the use time, in fact, this is a misunderstanding, the use time of the engine oil is related to the working conditions of the automobile engine such as performance, wear degree, driving road and environmental conditions, and at the same time with the quality grade of the engine oil and the anti-wear agent in the oil, anti-high temperature oxidation additives, and the viscosity of the oil is not related. The owner's manual has detailed instructions, you can choose the lubricating oil suitable for your own model, Kunlun lubrication has a complete range of products, reliable quality, for reference.

Due to the high viscosity of the oil, the frictional resistance of the friction surface of the parts increases. The friction area of friction parts in automobile engines is large. These surfaces are covered with a layer of oil, and when the movement speed of the parts is very fast, even if the viscosity of the oil increases slightly, the loss of frictional power will increase a lot, and in order to overcome the increased friction, more fuel will be consumed.

On the other hand, the viscosity of the engine oil is large, and the agitation resistance of the crankshaft at high speed will also increase, so that the power loss inside the engine increases, which also reduces the effective power of the engine.

How to choose a viscosity engine oil, what is the role of oil viscosity, and why must you consider oil viscosity when choosing a motor oil? Yacco French motor oil brand will tell you below: in fact, the bottle will have the viscosity of organic oil, and it is generally in a conspicuous position, you can see at a glance, the viscosity of the oil is very simple.

It is recommended that car owners check whether the engine oil has reached the cycle that needs to be replaced, and you can choose the oil with a relatively high low temperature fluidity mark in Kunlun lubrication.

The viscosity of the engine oil is not getting higher and higher, and the engine of the car needs to use the right viscosity oil. When choosing an oil, be sure to read the oil model specified on the manual. If the oil viscosity is too high, it will affect the power output and fuel economy of the engine.

Everyone must choose the right viscosity oil for their car. Engine oil is used by every car owner.

Engine oil is something that every car owner comes into contact with when they are using their car. If there is no oil in the engine, the engine of the car will not function properly.

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

When the engine is running, the oil will form an oil film on the surface of each component in the engine, which can prevent friction caused by direct contact between the parts in the engine.

If the parts in the engine are in direct contact and cause friction, it will increase the wear and tear of the engine, and a large amount of heat will be generated in the engine instantaneously.

The performance of the engine oil will be reduced after a long period of use, so it is necessary to change the oil regularly.

If you don't change the oil for a long time, it will increase the wear and tear of the engine.

Replace the oil with each oil change along with the filter cartridge.

The oil filter element is used to filter the oil. Without an oil filter, the oil will get dirty after a period of use.

When buying oil filters and oil, be sure to buy them from regular channels.

What's the harm of having a low viscosity of the oil.

If the viscosity of the engine oil is too low, the oil will not be able to form a stable oil film on the surface of various parts in the engine, which will increase the wear of the engine and cause a large amount of heat to be generated in the engine instantaneously. But some cars require the use of low-viscosity oil, which is related to the design of the engine.

Engine oil is something that every car owner comes into contact with when they are using their car. If there is no oil in the engine, the engine will not function properly.

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

If there is no oil in the engine, the engine will not run properly.

When the engine is working, the oil will form a layer of oil film on the surface of each component in the engine, which can prevent friction caused by direct contact between the parts in the engine.

If the parts in the engine are in direct contact to produce friction, it will aggravate the wear of the engine, and it will also cause the engine to generate a lot of heat instantaneously, which is fatal to the engine.

Long-term use of oil can reduce performance, so regular oil changes are required. If you don't change the oil for a long time, it will increase the wear and tear of the engine.

It is recommended that you change the oil on time when you are using the car, and change the oil filter element together with each oil change.

The oil filter element is used to filter the oil. If you don't have an oil filter, the oil will get dirty after a while.

Is the higher the viscosity of motor oil, the better @2019

The higher the temperature, the thinner the oil, and the thinner the oil film, which may face tearing under extreme conditions. The lower the temperature, the thicker the oil, the slower the flow of the oil, not to mention the increase in fuel consumption, but also more likely to cause cold start wear.

The viscosity index indicates the degree to which the viscosity of all fluids changes with temperature. The higher the viscosity index, the less affected the viscosity of the fluid is by temperature, and the less sensitive the viscosity is to temperature.

To put it simply, the higher the viscosity index of motor oil, the less affected it is by temperature, it is less likely to thin when the temperature rises, and it is not easy to thicken when the temperature decreases. Therefore, it is true that the higher the viscosity index of motor oil, the better.

Generally, the viscosity index of engine oil is generally around 160, and it is relatively high if it can reach about 170.

Some car owners think that adding a high viscosity lubricating oil can protect the engine, while some car owners think that using a low viscosity oil can save fuel, these ideas are all misconceptions.

To prevent friction in the internal parts of the engine, the oil must have sufficient viscosity to form adequate oil film protection at operating temperatures. However, the use of an excessively viscous engine oil will lead to slow internal flow of the oil, increase resistance, increase fuel consumption, and reduce the power output of the engine.

Although the fluidity of the oil is guaranteed by using an oil with too low viscosity, it is difficult to form a good oil film protection at the operating temperature, which will cause damage to the engine and also cause a loss of power.

Therefore, only the correct use of oil viscosity can make your car look its best. What is the best oil for your car's engine? Just check your vehicle's manual.

Of course, it's not the climate is different, the viscosity of the oil is different.

In terms of the selection grade of engine oil, it is mainly divided into two grades: viscosity grade and quality grade. Next, let's talk about how to understand the viscosity grade and how to choose the viscosity of the engine oil. And the high viscosity of the oil will have some damage to the engine.

For example, 0w-20 letters and numbers, 0w can be called multi-grade oil or all-season oil, which is an old concept, because the previous engine oil, may choose one type of engine oil in winter, and then choose another model of engine oil in summer, because the temperature is different, the selected oil model will be different. For now, only the same type of oil is used all year round.

The w in 0w refers to winter, that is, winter, and 0 refers to the working temperature that it can adapt to, which can basically be understood as the lowest temperature is minus 35 degrees. For example, if there are other 5W, then you can add the number before W to minus 35 degrees, that is, the minimum working temperature is minus 30 degrees, and so on.

Then the number after w is a viscosity of 100 degrees under the premise of this level. For example, when the viscosity of this grade is 20, in the case of 100 degrees Celsius in the general standard, the kinematic viscosity is between to, and if the number is increased to 100 degrees Celsius, then its corresponding 100 degrees Celsius will also increase its kinematic viscosity range. Therefore, the higher the number, the greater the kinematic viscosity it will be.

High viscosity means that the oil is more viscous, so the resistance of the stirring oil is relatively large, and the fuel consumption will be relatively high. The smaller viscosity is correspondingly more fuel-efficient. Therefore, the high viscosity of the oil will have some damage to the engine.

So how should car owners choose the right engine oil for their car? In fact, it is very simple, you can choose according to your own manual, as well as the engine oil when the vehicle leaves the factory. If you want to choose a high-viscosity and high-grade engine oil, as long as it meets the requirements of the engine operation, it is possible to choose the best fuel economy.

When the age of the car is relatively large or the total mileage is high, or the driving speed is relatively fast when driving, and the floor oil or oil temperature is relatively high, you can choose a slightly higher viscosity engine oil.

If the oil viscosity is too high, it will damage the engine, so choose the viscosity of the oil according to the temperature, the oil with high viscosity when the temperature is high, and the oil with low viscosity when the temperature is low.

If the viscosity is too high, it will damage the engine, and you can choose oil with different viscosity according to the season, for example, the viscosity should be higher in summer and lower in winter.

The viscosity of the engine oil should be judged according to the existing engine oil in the car; High viscosity engine oil, after combustion, will damage the engine to a certain extent, so you must be cautious when choosing.
