Here's another article.

According to the link below, dispersants help control varnish and sludge caused by low temp operations better than metallic based detergents. I found that interesting.

"Dispersants
A major development in the additive field was the discovery and use of ashless dispersants. These materials may be categorized into two broad types: high-molecular weight polymeric dispersants used to formulate multigrade oils and lower molecular weight additives for use where viscosity modification is not necessary. These additives are much more effective than the metallic types in controlling sludge and varnish deposits that result from intermittent and low-temperature gasoline engine operation."
