I've never had this, but I thought I'd look into it as it seems like an interesting question. From what I can tell, best case scenario is that it is condensation mixed with carbon. This would look like oil and it would happen if the car was sitting for a while. Are you 100% sure it's oil. If it is, that's another matter...
