I don't shut anything down while fueling.
They hold more oil and they are on the hwy at speed all the time not in stop and go traffic.
Yeah there aint no reason to change the oil in these trucks at 3000 miles(well maybe the HEUI injected Powerstrokes) most over the road trucks run close to 30,000 miles on an oil change and they run the same oil as we do mostly Rotella 15w-40...i change mine at about 10-12k

they hold more oil but its just to compensate for the bigger engine, its probably the same ratio of oil to displacement, and i realize that they are on the road all the time, but alot of us drive on the highway more then thru the city and i still dont think our oil is breaking down that fast and needs changed at 3k miles

I have a FASS on my truck, and the return line going back into the filler neck will spit out enough fuel and fumes to click off the pump sometimes, so I shut my Diesel off to fuel.
FYI>>15litre Cummins ISX holds 44 quarts. 5.9 Cummins holds 11 quarts.

My own personal preference, On the big truck, I usually shut mine off because while I am fueling I'll generally check my oil and give things a good once over under the hood. Many times that has worked to my advantage. On my pick up, it just kind of goes according to how I'm fueling, if I'm paying at the pump, I usually just leave it running but If I've got to go inside I'll shut it off.
As for the cool down period, I usually let my pick up cool down. I've had a turbo lock down before, it ain't pretty. In fact, it's rather violent. I happened to be cruising at highway speed when it happened, and let me tell you, sh*t got really interesting for about forty five seconds or so. For those of you who have not been properly educated on the finer points of turbo failure, imagine a twelve gauge shot gun going off in the cab of your truck, followed by copious amounts of white smoke rolling from under the hood and immediate power loss. Side bar on the smoke, roll your windows down because that smoke will be coming through your A/C vents. Kinda makes your truck look like something out of a cheech and chong movie. After you pull over and raise the hood, you'll discover a small fire caused by the oil from your dead turbo spraying down on the manifold!
As for the big truck, I go by the pyrometer, engine oil temp and water temp. If the pyrometer is below three hundred degrees, and my water and oil ain't too hot, I'll go ahead and shut her down.
That's my take.
