Use only when specifically recommended by the manufacturer. Use only when specifically recommended by the manufacturer. For certain naturally aspirated and turbocharged engines. Can be used in place of CC and CD oils. The center of the Symbol shows the oil's SAE viscosity grade.
Viscosity is a measure of an oil's flow characteristics, or thickness, at a certain temperature.
The lower the number the more easily the engine will start in cold weather. The bottom of the Symbol tells whether the oil has energy conserving properties when compared with a reference oil in a standardized engine test. With API SJ a set fuel saving requirement is incorporated within the API specification, and only one level of Energy Conserving is allowed. Widespread use of motor oils with these designations should result in an overall saving of fuel in the nation as a whole, but a particular vehicle operator may not experience a fuel savings as a result of using these oils. The energy conservation experienced by individual vehicle operators may differ because of many factors, including the type of vehicle and engine, engine manufacturing variables, the mechanical condition and maintenance of the engine, oil that has been previously used, operating conditions, and driving habits.
