Problems solved by technology

[0002] At present, the use of gasoline engine oil on the market has the following problems: firstly, the fluidity of the existing engine oil is poor at extremely low temperature, and the composition of the existing mineral oil is complex, and the fluidity at low temperature is not as good as that of synthetic engine oil, so it is not suitable as a blending component of internal combustion engine oil; secondly , the compatibility between the synthetic base oil and the mineral base oil in the raw materials of the existing engine oil is checked, and there will often be increased oil sludge and increased fuel consumption caused by engine operation; thirdly, the configuration and composition of the existing oil products are relatively complicated, and the production time is long. The emission is high and not up to the standard, and there are defects such as not being environmentally friendly, high fuel consumption, poor wear resistance, and weak power
