What is the equivalent of VW50200 engine oil?
1 Answers
vw50200 corresponds to the API SN grade, which is the highest grade of engine oil. It is the original equipment manufacturer (OEM) oil standard required by Volkswagen engines in Germany. Among OEM oils, both 5W-30 and 5W-40 grades meet the VW50200 standard. Additional information on engine oil requirements: 1. Friction heat: The general requirements for engines are small size, lightweight, compact structure, and high power output, resulting in significant load on the unit friction surface. 2. Combustion heat: The high temperature of the friction surface reduces the viscosity of the lubricating oil, making it difficult to form an oil film. 3. Oil contamination: High-temperature and high-pressure combustion gases in the combustion chamber can leak into the crankcase through the gaps between the piston, piston rings, and cylinder liner. These combustion gases are the result of complete and incomplete combustion of fuel and a small amount of lubricating oil, forming gases and certain particulate matter, which typically become the main components of crankcase blow-by.
