Abstract

The invention discloses high-performance internal combustion engine oil capable of performing viscosity classification and a preparation method thereof. The internal combustion engine oil comprises synthesized base oil, high-temperature antioxidant, metal clearing agent, ash-free dispersing agent, anti-oxidation preservatives, nano multi-effect abradant, viscosity index improver, pour point depressant and oiliness agent. The high-performance internal combustion engine oil has the advantages that the internal combustion engine oil is outstanding in energy conservation and environment protection performance, excellent in wear resistance and friction resistance, good in fuel economy, excellent in low-temperature flowability, outstanding in high-temperature oxidation resistance and high in abrasion resistance; the influence of temperature on the viscosity change of the internal combustion engine oil is small, the internal combustion engine oil can flow under a low-temperature condition and keep proper viscosity in a high-temperature environment, and the internal combustion engine oil can reduce engine wear and prolong the service life of an engine; in addition, the internal combustion engine oil prepared by the method is high in extraction purity and cannot be easily oxidized and degraded into oil sludge and carbon deposition, and accordingly the oil change period of the internal combustion engine oil is long.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a high-performance internal combustion engine oil capable of viscosity classification and a preparation method thereof. Background technique [0002] With the gradual popularization of automobiles, people have higher and higher requirements for vehicle maintenance. The performance of green environmental protection, energy saving, high temperature resistance and high friction resistance will become the development orientation of the new generation of automobile lubricants. The application of high-tech and high-performance additives, supplemented by the excellent characteristics of synthetic lubricating oils, will endow engine oils with better performance in many aspects. [0003] Lubricating oil additives are the main way to improve the quality of lubricating oil and expand the variety of lubricating oil, and also an important means to improve the performance of lubricating oil, sav...
