I understand the opinion bit. But according to your experience, you could tear the engine down and clean it. Or, you could try a solvent in the oil. It sounds like you only do in the former.
If you disassembled your engine, you would probably clean the parts in some kind of solvent. Why wouldn't solvents added to the oil have a similar effect?
