I would lean toward exposed pipe dope. It separates and must be stirred occasionally. The oily substance I have found on sprinklers looks just like the oil in the compound. If it were from the fittings, I would almost certainly think we would see water. Since most helpers (I in the day) use the glob/brush method, I would think there is enough outside the threads to separate over time. Even years.
