What is the oil grade corresponding to VW50200?
1 Answers
VW50200 is an oil standard set by Volkswagen in Germany, corresponding to the API SN grade. Only oils that meet this standard may be used as original equipment manufacturer (OEM) oil by Volkswagen. The API grade is a quality standard for engine oil established by the American Petroleum Institute (API). The "S" designation indicates specifications for gasoline engines, while "C" denotes specifications for diesel engines. The functions of engine oil are as follows: 1. To separate the surfaces of relatively sliding parts, reducing wear. 2. To carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine. 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away contaminants generated on the working surfaces of parts through the flow of the lubricating oil.
