Problems solved by technology

At present, in order to achieve a better fuel combustion effect, the operating temperature of the engine is increased, especially in the engine equipped with a turbocharger. The common engine lubricating oil on the market is easy to evaporate and lose at high temperature, so it needs to be checked and added frequently. , thus causing unnecessary waste and increasing environmental pollution
If it is not found in time, it may cause engine damage, resulting in greater economic losses
In addition, the lubricating oil sold on the market has a relatively high pour point, and it has a poor lubricating effect on the engine when starting a cold car or starting in some cold regions, and accelerates the wear of engine parts
Some lubricating oil products will break the oil film at high engine speed, which will not protect the engine and shorten its service life
