> every time I belched black smoke
If you've got visible smoke coming out of a diesel (in any color), something's wrong with the engine.
"Rolling Coal" is a thing in some parts of the USA.

Well, the dirty looks I got every time I belched black smoke on the streets of SF were a given. What I did not expect (or notice previously) was the other truck drivers (however few) there were in San Francisco. It seems I too was inducted into a little club. Whenever I saw another truck there was always a thumbs up, or a "nice truck". Kinda funny when all I got was dirty looks from everyone else.
