I know, I know, use the search...........but since we are having another oil thread anyway, is just about everyone using synthetic in their diesels? I have 2 diesels but have not switched and wondering if I should.

Besides longer "potential" intervals between change, are the lubrication advantages worth the difference in cost?

Which brand is best? And there are no issues switching in a high(er) mileage engine. For some reason, I used to think (or be told) the one switched right after a car was broken in or not at all. At least with american gassers.
