A third advantage is that engine longevity on Diesels is almost
inevitably better-a lot better-than gasoline engines. Most of the
indirect injection mechanical diesels sold in cars and light trucks
far outlived the chassis in which they were sold. The Benz engines are
the only ones commonly left, aside from a few VWs.

Re: Diesel engines: better low-end torque?
I have no bitch at all about the diesels used in pick up trucks
pulling trailers at fifty five miles an hour, that's what they were
designed to do. Their pollution is just a fact of life:
