I use Wynns Engine flush before oil changes on my diesels, but many on Forum feel that it disturbs any particles and causes more problems.
Either way I don't think that will cure your black smoke issue as I said before.
Black smoke is either too much fuel or not enough air on a diesel engine, I learnt that 50 years ago.
