I have a 2012 F250 6.7L. Is this stuff ok to use? Does anyone else use this?
I like "Howe's" additive myself and have used it for years. Never had any problems with "Seafoam" products, and it is popular around here, but I'm not really one to change what is known to work.

A couple of my customers have the same type powertrain as you and also use "Howe's" with no detrimental effects noticed through two winters I'm aware of.
