Diesels shouldn't really smoke much more with age. A good tuned diesel will hardly smoke at all. Black smoke can be caused by a restricted air filter or even a fuel filter as well.
Do diesels smoke more as they age?

I drive a Freightliner with a Cummins. One of the best running trucks i have driven in a long time. And to the OP your trash truck's smoke is most likely due to poor maintenance. They don't take care of those trucks until they break.
