The new pictures don’t look great, but prior photos look worse. IMHO and experience, it’s not normal.
Metal does not belong in motor oil, especially at 50k miles. But, like others have said, an analysis will at least give you a little idea of what is in the oil, and if it’s in the normal parameters.
If the dealership is blowing this off, I’d ask the service manager for the regional reps contact info and I’d forward the photos and info to both the regional rep and Ford customer service. If anything bad happens later on, at least you have documentation.
On an aside, the service managers reaction to your request for the regional reps contact info will be telling. If he pushes back, my first question to him would be, “if it’s normal and there’s nothing to hide, why would you care if I contact the regional rep?”
Also, if this is “normal,” why aren’t there dozens of posts here with people who have seen the same thing? And, where is that “normal” metal coming from?
I’ve owned multiple Ford ecoboost products, Focus St, Focus RS, F150 Raptor….None have had metal in the filter.
