Last night we had an MD-88 taxi into the gate with oil on top of the flaps. I never see oil on top of the flaps or the wing, but I have seen it on the bottom and off the engines. I told the capt. while he did his walk around but I never got to ask him where it would come from because we were offloading the plane. I did see him call MTC then check both mains and walk around to the other wing and look at that and then go back to the other side and he talked for a little bit more and that was it.
Does anyone know where that oil would come from? It was more in-bored close to the main gear area but on top of the flaps.

It was probably grease. After sitting in the airstream, it takes on a look of oil staining. The grease comes from an over-zealous person with a grease gun during routine maintenance. If you don't wipe-off the excess it gets everywhere. Hell, even if you do wipe it off, it shows up in the dardest places.
