This engine is broken in already, these particles just didn't appear out of some crevice in a casting somewhere something is causing them.
In over 35 years doing this for a living i never saw a engine just start shedding specs of metal no matter how small unless it was a unit with gearbox attached and shared the same oil e.g original Mini's and motorcycles.
This is the fifth OC and you notice it on this one and not the others? That is a good indicator IMO.
You need to document this ASAP with the dealer even if they say there is possibly nothing wrong.
It may be nothing significant but on the other hand who knows.
As far as people claiming you can run 0w20 in this engine don't believe everything you read on a forum.
If Ford saw fit to allow its use they would have spec'd it or at least allowed it as an alternative.
If they don't there is a good reason especially when this a 2011 engine, its not like the oil was unavailable when the engine was built.
