Recently, the Guangzhou Municipal Administration of Industry and Commerce announced the monitoring of the quality of automotive lubricants sold in the circulation market in Guangzhou in the second half of 2013. Of the 46 sampling samples produced by 31 manufacturing enterprises, 34 samples failed to pass the inspection. The products of the European Wing, Zhongguan, Niueer, Alpha Pineapple, and Anaichi were found to be unqualified. Judging as unqualified, the failure rate was 26.1%. It is understood that this sampling inspection is based on the national mandatory standards, product or its packaging on the express use of product standards, the automotive lubricants kinematic viscosity, low temperature dynamic viscosity, high temperature and high shear viscosity 12 items were tested. The test results showed that the indicators of low temperature dynamic viscosity, flash point (opening), kinematic viscosity, high temperature and high shear viscosity, pour point, foam, and evaporation loss were unqualified, among which the products that failed the low temperature dynamic viscosity index accounted for unqualified Half of the product. It is understood that when the low-temperature dynamic viscosity fails, the lubricating oil cannot be pumped to the moving parts in time through the engine oil, resulting in a large starting wear. The use of lubricants with poor low-temperature kinematic viscosity, when the weather is cold, is prone to engine start-up difficulties, and can easily cause piston ring and cylinder liner wear.
