Since the Wx has been somewhat colder then normal at times, after the car has not moved for two-three weeks, I've noticed small amounts of oil droplets on the floor in my shop below the differential and over these past two weeks below the engine ( from where, I don't know just yet, because of the under pinning).
My question I guess, is, is this normal due to cold weather? Seems like once I drive the car and get things back to normal temp wise, there are no longer any indication of seeps or leaks in these area's

Thanks in advance---
