Agreed with the "Properly maintained" engines not smoking. Unfortunately, there are a lot of people that do not properly maintain their vehicles.A properly maintained gas engine will not smoke, even when at full throttle. An older (pre DEF) diesel will have soot in the exhaust on heavy throttle, however a newer truck should not unless they have defeated emissions control devices. If you see a fairly new truck spewing black clouds it is entirely intentional.
I personally know 3 people that drive fairly new (less than 5 yrs old) and well maintained diesels with zero modifications, and they all have some soot in the exhaust when flooring the vehicle. Noticeably less than pre DEF engines, but there nonetheless.
