What is the classification of diesel engine oil?
1 Answers
Diesel engine oil is roughly classified into: CA, CB, CC, CD, CE, CF, CF4, CG4, CH4, CI4, CJ4. Different grades of diesel engine oil indicate varying oil quality levels and corresponding suitable vehicle models. In other words, the further the letters are arranged, the higher the oil quality grade. The English letter 'C' at the beginning represents diesel engine oil, and the further the letters are arranged, the higher the oil quality grade. Generally, CD-grade oil is sufficient for ordinary diesel engines, while turbocharged diesel engines require higher oil quality, such as CF4, where '4' indicates that the oil is suitable for four-stroke diesel engines.
