Dragboat, the Motorcraft that I recently purchased for my Explorer also had a light coating of oil on it. It was very thin oil, almost like sewing machine oilquote:

Depends on whats used I guess. Proline paper filters sold at Pep Boys has a oily feel to it and it works very well.
The oil analysis of my Daughters car showed this to be a very good air filter,,would like to know what they put on them out of curiosity
