Can you tell ... by the smell?

With Detroit's being the worst IMHO very sooty smell (diesel mechanic)

I know I could tell if it was a Cummins, Detroit or a Cat by the smell of the exhaust, all burning the same fuel.

Yup, pretty easy to tell apart from the sound too. Also 7.3 Powerstroke too, very distinct sound/smell

I can tell from a whiff when out in the back yard if the furnace is burning hot/clean...or not. Hot/clean is a nice light roasted wood smell, cool/dirty has that pungent, strong creosote smell. To me the smell is more accurate than the presence of (or not) smoke

There is no other diesel that sounds like one of the old screaming Jimmy's.
