Sounds like you are getting backflow from the sewer. As the waste gets flushed down through the waste pipes going to the sewer, some of it will stick to the wals of the pipe. As it breaks down, it usually becomes black and oily. Greases and oils are particularly prone to sticking to the pipe walls, so when there is flow that comes back up through the waste pipe, it will pick up some of this decomposing grease and oil, thus rendering the resulting backflow oily.
