Zoom in & brighten the picture, It's no theory & those holes are not "Nice little Holes" either. Certainly not uniform & most certainly from debris. OP car was using 20 grade to boot when this engine should be using a 30 grade IMO but Ford needing to increase their numbers.

I used 5w20 once at 96,720 miles and have used 5w30 ever since. Previous owner likely did use 5w20 though.

^^^ Yep, like said, without any engine UOA trend data: "A real major wear issue might be noticeable right off the bat if the wear metal levels are crazy high." Since you had at least some UOA history data on that engine that helped to see just how far out of bed the wear metal was, and that helped raised the red flag because it was way out of the norm. Just looking inside the oil filter for visible metal debris would have raised a red flag too.

Thanks for the details. Yeah, Not out of the ordinary, I know several folks who jumped on Ford's 5w-20 recommendation over the years. All of a sudden OLD engines were okay but I wouldn't & doesn't sound like you are convinced either.
