Some netizens are often seen on the Internet and talk about the quality of oil. Some netizens even though they are very knowledgeable, there is a lot of misunderstanding about the oil.
At present, the use of low-viscosity oil is a trend. The major auto manufacturers in the world have also consistently promoted the use of low-viscosity engine oil as an after-sales service oil for automobiles. So, what are the benefits of using low-viscosity oils for automobiles?
1 The use of low-viscosity engine oil is a requirement for the development of engine technology. Modern technology makes the engine more and more precise, and the engine clearance is also getting smaller and smaller.
The precision engine does not need to rely on the large viscosity of the oil to improve the engine's tightness. The low viscosity oil can fully meet the sealing requirements of the precision engine.
2 The friction pair of the engine has been processed by the advanced manufacturing process with a very smooth, low-viscosity oil that provides better lubrication on smooth friction surfaces.
3 The viscosity resistance of the low-viscosity engine oil to the crankshaft is small, and the small viscous resistance means that the fuel consumed by the engine will be reduced accordingly.
The reduction of fuel consumption means that the emission of exhaust gas will be reduced accordingly, which means that low-viscosity engine oil is more powerful for environmental protection.
Oil and water-like, meaning outside the word, that is the viscosity of the engine oil is great, in fact, this understanding is a big misunderstanding, I ask the water there is no lubrication effect?
Of course not, water is a very good lubricant. For example, when our hands touch the glass, the surface of the glass will be very astringent. If we sprinkle water on the glass, the surface of the glass will become very slippery. This proves the lubrication effect of water. very good.
Of course, water cannot be used as a lubricant in the engine. This is not because the water does not have a lubricating effect because the first water will cause the steel to rust, and the second water has a boiling point of only 100°C and will evaporate quickly in the high-temperature engine. So water cannot be used as a lubricant in the engine.
