Are Short Trips bad for diesel engines?

Short trips are less detrimental on Diesel vehicles than they are on gas powered rides. Gasoline condenses and washes down cylinder walls into the oil when cold, diesel does not. cold diesels will produce more soot, so long term you would be into sticky VNT vanes or a (again) clogged intake.
