Without DEF, you’d have trucks billowing smoke from the stacks again as you used to have with trains. It’s for emissions. Not performance.


That's incorrect. The DPF (particulate filter) is for the smoke, DEF is for NOX emissions.

And to add... my deleted diesel RV does not blow black smoke at all.

18 wheelers weren't constantly blowing black smoke before 10 years ago. Unless it's just a shitty trucker, you control it entirely from over revving. Unless there's just a really steep hill or a quick emergency type situation it didn't happen often. It wasn't really a problem
