What is the VW 50200-50500 Standard?
1 Answers
50200/50500 engine oil is a certification standard for engine service oils by German Volkswagen, corresponding to the API-SN grade of engine oil. Only oils that meet this standard can be considered as original equipment manufacturer (OEM) oils by Volkswagen. Since VW50200 corresponds to the API-SN grade, when selecting engine oil, you can confidently use any oil that meets or exceeds the API-SN grade. Below is a detailed introduction to engine oil: 1. Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10(kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber in the engine. It is often referred to as the 'blood' of a car. 2. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricants, determining their basic properties, while additives compensate for and enhance the performance of the base oil, providing new characteristics. Additives are an essential part of lubricants. 3. The API grade is a quality standard for engine oils established by the American Petroleum Institute (API). 4. The 'S' designation indicates specifications for gasoline engines, while 'C' indicates specifications for diesel engines. 5. This grade is an environmental indicator and is not directly related to performance. Higher grades indicate better environmental performance and fewer harmful emissions. Currently, most new engine oils on the market are SN grade.
