I noticed this morning that they were tiny ( quarter & nickle sized) spots of oil under the front of the car. Never seen this before and the car was sitting for full day and night. When I looked under the car (see pics below) I noticed some parts of the under carriage were saturated with wet oil that came right off on my finger tips. I have no idea what I'm looking at

used (see pics) nor whether I should call a BMW mechanic.
Has anyone experienced this before?
My car is a 1995 318i. I'm due in about 20-30 days for oil servicing.
Thanks
