I actually agree, especially with injector cleaners in the fuel tank. They just cover up problems that need addressing. Straight diesel purge
might clean the injector tips, but I don't think anyone can be sure of that. When I did a diesel purge, the pinging went away for a little bit, but came back in a month or two. I needed new injector tips. I don't think they make significant difference.
I do use iso-heet, however, to remove water from the tank, but that's it.
