I'm with Zip on this one.
Any break-in lube should of disolved and been long gone by now, however contaminates such as water and unburned fuels from poor ring seal will build up on the bottom pan and can eventually clog up your oil pump pick-up, you need to pull the pan and clean that gunk out - address the real problem.
Years ago people who added that STP garbage every oil change would have similar problems, seen that stuff 3 inches deep in a pan before.
