What kind of engine oil can effectively clean the engine and remove carbon deposits?

The cleaning ability of engine oil is mainly to wash the carbon deposit, paint film and sludge from the friction surface through solubilization, dispersion, washing and neutralization, so as to keep the engine clean and ensure the high stability of engine oil. In this process, the quality of base oil is very important. The Maroon 5 engine oil I have been using is very good in this respect, mainly the quality of PAO base oil is good. After driving for several years, the engine has basically not produced serious carbon deposit, and there is nothing to say about the clean and protective ability of the engine.
