Max,
Back in the good old days - two or three years ago - diesel at the pump was low sulfur. Now, from the pump, it is ultra low sulfur.
That small reduction is enough to remove the lubrication the engine needs. The practical solution is to add biodiesel. Even 5% is enough to restore the lost lubricity.
(I guess the IP, the injectors, and the engine internals need the improved lubricity.)
The sad part is that is not illegal to sell low sulfur diesel. It is only illegal to put it in a 2009 or later car or truck. So everyone is paying a higher cost per gallon and risking damage to their engines for the benefit of a small percentage of drivers. Almost enough to make you believe in conspiracy theories.

In air brake equipped vehicles, drive as soon as you have air. Sulpher is a good lubricant, so it is not recommended to idle diesels for more than a few minutes. Most truckers shut their engines down after letting the temps equalize, or set the engine to fast idle.
