Do you leave your diesel running ...?
I see many diesel drivers who leave the engine running while fueling (or other short-term occasions). For a while, I asked why they did that, just to see what their reason was. Never got the same answ...

I lived in the upper midwest for a long time. During the winter, the 18 wheeler guys would not shut down their rigs for a couple reasons, but I believe that one of the main ones was because a running engine circulated the fuel from the fuel tank to that nice warm engine and then back to the tank. The fuel stayed warm which kept it from jelling up.

Exactly... when its -30...-40 or colder your gonna want to leave that diesel idling, especially if your an OTR trucker living, sleeping, eating and doing bookwork, in that sleeper/office. In my long drives to various work sites, I will use a rest stop idle up the engine and grab a catnap(some of my commutes can be 10 or 14 hrs). In my 2005 Ram with the diesel heater it was set up to turn heater fan on, kept the coolant hot and the cab warm...but if too cold the fuel could jell, so, idling was the trick. In my 2013 Ram, due to the newer electronics I can no longer have the heater fan run with the diesel heater, so I'm stuck with idling for a couple hrs while I get some shut eye, which is ok as I'm keeping my fuel warm as well.
