Polyalphaolefin synthetic oil has been widely used in automobiles. The advantages of synthetic oil used are as follows:
• Improve engine cleanliness - For example, the engine oil based on polyalphaolefin oil is very clean after driving more than 60,000 kilometers.
• Improve fuel economy - Polyalphaolefin was tested under 10 test procedures on 182 vehicles, and the average fuel saving was 4.2%.
• Improve lubricant economy - After a variety of different test methods, the unit consumption of polyalphaolefin lubricant can be saved up to 156%, and the average unit consumption can be saved by 55.9%.
• Excellent cold start performance - When polyalphaolefin oil is used as engine oil, it can be started directly at -40℃, while when using mineral oil of the same viscosity grade, the minimum cold start temperature is -34℃.
• Excellent low temperature fluidity - The pour point of engine oil based on polyalphaolefin oil is -54℃, while the pour point of mineral oil engine oil of the same grade is -38.3℃.
• Extended oil change period - after test comparison, the engine oil using polyalphaolefin as base oil is compared with other engine oils, and the replacement cycle of engine oil and oil filter is longer.
• High temperature oxidation stability - for example, when polyalphaolefin oil is used as base oil in an engine, the viscosity increase value is only 10% when it is operated at a tank temperature of 150℃ for 64 hours, while the increase of mineral oil base oil is 135%.
It can be seen that polyalphaolefin as an engine oil can meet the performance requirements under the harsh use conditions of today's advanced automobiles. It is not only better than mineral oil in thermal oxidation stability, but also its thermal conductivity and heat capacity are about 10% higher than the corresponding mineral oil. Therefore, equipment using polyalphaolefin lubricants can dissipate heat and cool faster.
