Base oil, additives such as Calcium are detergents but they don't clean dirt and sludge that is already there, they just prevent the formation of new deposits.
Oils with a high ester content are well known to be good at cleaning, and actually also Group 1 conventional oils, Group 1 is at the same time the "dirtiest" type of base oil, but also it has pretty good solvency compared to something like a Group III HC oil or PAO, because they have a large amount of Aromatics compared to other bases, PAO or GTL are the "cleanest" base oils, but really don't have all that much solvent power.
Hope that makes sense

You might also consider sending a PM to @High Performance Lubricants as they are very smart and capable individuals that make an oil specifically for cleaning.

Stumbled upon this recently. Amsoil blog
"Lubricants maintain internal cleanliness by suspending contaminants within the fluid or by preventing the contaminants from adhering to components. Base oils possess a varying degree of solvency that assists in maintaining internal cleanliness. Solvency is the ability of a fluid to dissolve a solid, liquid or gas. While the solvency of the oil is important, detergents and dispersants play a key role. Detergents are additives that prevent contaminants from adhering to components, especially hot components such as pistons or piston rings. Dispersants are additives that keep contaminants suspended in the fluid. Dispersants act as a solvent, helping the oil maintain cleanliness and prevent sludge formation."
With modern formulations, who knows what they're using in place of ester cobases in some of these blends.
