Why diesel engines last longer than gas engines

One of the main reasons diesel engines last longer than gas engines is diesel fuel comes from a lower petroleum distillate than gasoline and it lubricates the fuel pump, injectors, which helps reduce the wear on the engine. Another reason diesel engines last longer, is they are made to driven on more, than any other engine. A third reason that a diesel engine can last longer than any other engine, is they are overbuilt so they can last.
