1 Answers
When selecting engine oil for diesel vehicles, you can choose based on quality grade and viscosity grade. The selection should consider factors such as local temperature conditions, the actual condition of the vehicle, and the recommended viscosity for the engine model to pick the appropriate viscosity oil. Diesel engine oil grades are roughly categorized into: CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, CJ-4. The different grades of diesel engine oil indicate varying oil quality levels and corresponding suitable vehicle types. In other words, the further the letters are in the sequence, the higher the oil quality grade, and so on. The highest grade of diesel engine oil is: CJ-4. Diesel engine oil grade specifications: The English letter 'C' at the beginning represents diesel engine oil. The further the letters are in the sequence, the higher the oil quality grade. General diesel engines can use CD-grade oil, while turbocharged diesel engines require higher-quality oil, such as CF-4, where '-4' indicates that the oil is suitable for four-stroke diesel engines.
