From the photo and knowing it came off a 2010 Mercury Milan Premier, this looks very much like a broken oil pressure sensor (oil pressure switch).

Here’s why that fits 👇

===== - Black plastic body with a hex (meant for a wrench) =====
* Metal threaded section that screws into the engine block
* Oil residue on the tissue
* Looks snapped, with the metal end separated from the plastic housing

That’s exactly how the oil pressure sensor is built—and they’re known to crack or shear off when aged or overtightened.

===== The oil pressure sensor: =====
* Screws into the engine block
* Monitors oil pressure
* Sends the signal to your dash light or gauge

===== - Oil leaking from the engine =====
* Oil pressure warning light coming on
* Engine may shut off or refuse to start (depending on failure)
* Oil spraying or dripping quickly after start

===== - Near the oil filter housing or =====
* On the side of the engine block
* Often toward the rear of the engine, closer to the firewall

===== - Do NOT run the engine until this is fixed — you can lose oil fast =====
* The broken threaded piece may still be stuck in the engine
* It will need to be: - Carefully extracted (easy-out or extractor), then - Replaced with a new oil pressure sensor

===== - The part itself is cheap ($15–$40) =====
* Labor is usually quick unless the threads are badly stuck

If you want, tell me:
* 2.5L or 3.0L engine?
* Did oil suddenly start leaking?
* Did an oil light come on?

I can then:
* Confirm 100% which sensor it is
* Tell you exact location
* Walk you through removal/replacement step-by-step 👍
