Quality indicators According to the API quality classification method, engine oil is divided into gasoline oil series(ie, S series) and diesel oil system(ie C series). The oil products of each series are arranged in alphabetical order(A, B, C, D, E, F). Divided into several levels, the more the letters are ranked, the higher the level. Selection Method The logo on the engine oil packaging sold on the market currently consists of the SAE viscosity classification level and the API quality classification level. Usually begins with SAE, followed by a viscosity code; The engine oil number classified by API quality is generally omitted from the API, and the quality level code is directly marked. For example, the label number is SAE10WSD, which means that the viscosity classification is SAE10W and the quality level is API SD's winter gasoline engine oil; The label number is SAE30SD, which represents the viscosity classification SAE30, and the quality level is APE SD's summer gasoline engine oil; The label number is SAE10W-30SD(or SAE10W/30SD), indicating that the viscosity classification satisfies both SAE10W and SAE30 winter and summer general gasoline engine oil, and its quality rating is API SD level. 荐 ，桂东县美孚机油经销，苏仙区美孚机油零售，资兴市美孚机油批发
