Diesels get great fuel economy, but on days like today they don't run

Diesels powered vehicles get better fuel economy than their gasoline powered counterparts and with advent of turbochargers their drivability improved to the point they became widespread, particularly in europe. If you haven't driven a vehicle powered by a diesel you might be pleasantly surprised. The do suffer from a problem a lot of people don't know about though. Days like today bring it home for us diesel drivers. First off the colder it gets the harder they are to start but right down just a bit below 20 or so degrees the problems gets worse. The fuel turns to jelly when it gets cold that cold and jelled fuel won't pass through fuel pumps. Dead in your tracks, the things won't go anywhere.

As more and more of them are built and find their way onto the roads I thought this is something more folks should know about.
