Three rumors of lubricants, do you know?

<

For the lack of professional knowledge of the card friends, the purchase of oil is somewhat confused it? It does not matter! Xiao Bian Shell as an example for everyone to enjoy the oil to buy three sentences of pursuing a secret, pack your chest to buy good oil!

The first sentence: The low temperature viscosity determines how far to run, the high temperature viscosity determines how much

General oil packaging is marked with a similar "0W-40" viscosity grade, which is a very important parameter to buy oil! Low temperature viscosity determines how far to run, 0W that the engine oil can support the engine at minus 35 degrees or even lower temperature Work, snow and ice ride. The high-temperature viscosity (such as 40) decided to run more cool, consumer automotive oil common high-temperature viscosity indicators 20,30,40.

For the average consumer, the lower the high-temperature viscosity is, the more fuel-efficient it is, and the higher the viscosity, the more suitable it is for older engines and engines with very high operating temperatures. It is recommended that patients with motorcycles, old vehicles, or burned oils have an optional high-viscosity engine oil (eg, 40), while daily city driving, new vehicles, and fuel-efficient parties can choose low-viscosity (eg, 20 and 30) engine oils that meet the original viscosity requirements. Oh! Did you get it?

Second sentence: Want to love your car for a long time

We all hope that the car can be saved worry-free for more than a few years. Buying good oil is like buying good skin care products. It can keep the car alive. With the development of science and technology, engine oil is roughly divided into mineral oil, semi-synthetic oil and total synthetic oil. In the field of synthetic oils, Shell's exclusive PurePlus technology can directly convert natural gas into a pure, fully synthetic base oil. After the base oil and additive are perfectly blended, Heineken Ultra has excellent performance in many aspects such as easy flow at low temperature, high temperature viscosity, high temperature volatilization, and clean protection.

Although the total price of synthetic oil is slightly higher, it is wise to consider comprehensive engine protection, automotive performance improvement, and saving fuel and maintenance costs.

The third sentence: Do not hesitate to change the oil, do not dare to clean the oil

The problem of the oil change cycle is often puzzling. It has a direct relationship with oil. It will also be affected by fuel quality, air cleanliness and driving habits. The old driver suggested that when the engine sounds louder, the power is reduced, and the fuel consumption increases, the oil is changed when the oil is changed.

Most people's attention is usually focused on the brand, price, and parameters of the engine oil. It is also important to ignore the engine oil used in the oil change process. Shell Tmall flagship store not only provides high-quality genuine oil, but also supporting Shell cleaning oil, antifreeze and so on.


Substrate

The formation of fluoride crystal mica is a sub-grade, and does not adsorb impurities. It was selected by the Chinese Academy of Sciences Environmental Biology Research Center Peking University, Tsinghua University, Shanghai Fudan University, Nanjing University, and more than 100 national research institutions and universities for AFM substrate After (microscopy carrier wave), the relevant person said: Compared to natural mica, fluorite mica has better flatness and less adsorption impurities. The images observed in the analysis of the DNA structure, especially in the 1 nm to 100 nm scale, have observed surface interference fringes not found in the natural mica experiment, which are clearly dozens of times better than the natural mica substrate. Experts involved in the experiment believe that the use of fluoride mica instead of natural mica as a substrate material is expected to catch up with the international level.
