There are extra detergents and esters in Rislone that will clean, if you indeed have a bona fide issue with sludge and deposits. However if you've been diligent about a) using a quality lube and b) changing your oil on time, then you likely have little to no sludge/deposits to begin with. So you might not notice a meaningful change in DS color (right off the bat) outside what is normal for you, if you don't have a big problem to begin with. But like demar' said, give it some time to see what develops. The active ingredients are slow acting and meant to be left in for a full drain interval so they can do their trick.
