How to choose the right lubricating oil for different vehicle systems?
How to choose lubricating oil for different car series? It is believed that most people will have such problems. The choice of lubricating oil is also related to the temperature of the use area, personal driving habits and other factors. Here are the following points for you:
Let's first understand the international commonly used lubricating oil grade standards, so as to better choose lubricating oil:
1.German system:
In German cars, the internal working pressure and temperature of the engine are generally high, and the requirements for lubricating oil are high. Therefore, it is recommended to use the oil meeting the ACEA standard. Generally, the words "ACEA" will be marked on the outer package of the oil barrel.
2.Japan and South Korea
The engine design of Japanese and Korean series cars is relatively precise, and the requirements for lubricating oil are not as strict as those of German series cars. Generally, they prefer low viscosity oil, which can meet the SM and Sn levels of API standards, and 0w-20 or 5W-30 can be selected for viscosity
3.American Department
American Series cars are similar to Japanese Series cars. They are suitable for using low viscosity oil. The viscosity of 5W30, 5w40 and 0w40 are all OK. Oil with ACEA A3 / B4, A5 / B5 or ILSAC gf-5 grade printed on the package is also suitable for American Series vehicles. If it's a GM model, you can recognize the logo of "dexos". It's also a low viscosity engine oil, which has passed the certification of American GM demos. It's undoubtedly very suitable for GM models
4.Domestic
The technology of domestic vehicles tends to be Japanese American series, such as Haval, Chery, Zhongtai, Dongfeng and other independent brands, so the lubricants that generally meet API or GF standards are applicable, and the viscosity requirements are the same.
