If you have an oil leaks, changing to a high detergent full synthetic or using an idle flush can make oil leaks worse, as the sludge and varnish can help old worn or split oil seals or gaskets work (It's called the false oil seal effect). In a bad case it might be best to use an HM oil or even some stop leak as a precaution after flushing.
As i mentioned in the initial post, the pan was dropped and cleaned out during the service. What is a 15 minute oil flush going to clean out that the prescribed LC20 isn't going to remove over the next couple thousand miles? Not trying to be argumentative, I'm just not in a rush and would prefer to play it safe.
