AI Technical Summary

Problems solved by technology

There are relatively few general-purpose lubricating oils in my country, and there are relatively many lubricating oils mainly for a single type of engine oil, and the gasoline engine oil or diesel engine oil mentioned in the patent mainly uses mineral oil as the base oil, and the obtained lubricating oil has a low viscosity index. Limited by the ambient temperature, the freezing point and pour point are high, and the lubricating oil often freezes when used in winter in the cold northern regions, which affects the use effect, which brings inconvenience to people's use.
