Perhaps a another relevant question is that to Synthetics oils burn more cleanly that dino stuff.
I read somewhere that when synthetics burn off they turn to ash which is then easily solvated by the detergent/dispersant additive package.
However it said Dino oils turn to coke and sludge when burned off. And this is the cruz of the dino versus synthetic debate...in that synthetics maintain superior engine cleanliness (generally speaking) over thier dino counterparts.
