What are the grade models of diesel engine oil?

[JasonLee]

Diesel engine oil grades are roughly divided into: CA, CB, CC, CD, CE, CF, CF-CG-CH-CI-CJ-4. The different models of diesel engine oil grades indicate different oil grades and corresponding applicable vehicle models. That is to say, the further back the letters are arranged, the higher the oil quality grade, and so on. Therefore, it is not difficult to conclude that the highest grade of diesel engine oil is: CJ-4. Relevant information about fuel additives is as follows: Classification: Fuel additives are divided into gasoline additives and diesel additives based on the usage object. In terms of function, they are generally divided into three categories: cleaning type, maintenance type, and power enhancement type. Function: Due to poor atomization and incomplete combustion, fuel forms a large amount of black smoke. Fuel additives can effectively reduce the combustion activation energy, improve atomization efficiency, and allow the non-combustible colloids in the fuel to fully burn, thereby eliminating black smoke and reducing emissions.
