What's the history of the unit? Did oil just suddenly appear after cleaning the filter for years with no accumulation?
Used unit first filter cleaning by you? New unit?
I'm also inclined to think cooking grease. Do you fry stuff on the stove? AC is probably pretty close. I've seen very greasy filters on range hoods.
If it is leaking from refrigerant system, it is not long for the world. Slight chance of a bit of leakage from overzealous lubrication of fan motor.
