Do you leave the truck running or shut it down? I Know the big rigs leave them running and I've noticed other diesels do both. So what do you do and what's your reasoning?
I generally shut it down, it takes so long to pump 40 gallons in that it's not worth leaving the thing running for that long. I top off until the fuel is all the way at the top of the filler neck too, so it takes a bit longer. If I lived where it was super cold I might leave it running, but in CA what's the point? Maybe this thread should be moved to the general forum?
I keep mine running for three reasons... 1. The 2002 and earlier Cummins doesn't use hardly any fuel idling anyway. 2. Get to keep the A/C going or the heat going 3. Getting to excercise the fact that diesel trucks don't have to shut off and gassers do is kind of fun. imp:
I leave mine running - mainly to let the EGT's come down, don't see the need to shut the motor off when I can leave it running and keep oil circulating taking away heat. The other reason is it sure does feel good to get back in the cab when the A/C is COLD as can be ...... Tom
I also tend to leave mine running, even though it takes a while to pump 50+ gallons. As suggested, keeps the truck cool, and saves on starter/electrical stress.
Yeah, and the motor itself wears less idling in that five minutes than it would restarting it by a long shot.
If I`m pulling heavy or the wife and kids are inside and it's hot, I'll let it run. If niether of those conditions exist, I'll shut it off. Marc
From what I understand it's alot eaiser on a Diesel engine to idle due to the engine temps being able to drop while idling on a hot day preventing heat soak and posiable dry-lube starts. Plus as mentioned before less stress on the electrical/starter and keeps the A/C-Heater at temps. Of coarse in the winter time it helps to keep the engine at operating temps.
he he.. OOPS!! California is now a "No Idle" state. if you are not in te drivers seat they CAN ding ya. its a new lay and i have yet to hear of it being enforced... but its there. i know in a lot of residential areas they will talk to you, BUT i have yet to hear of anyone being cited. oh, and to the origonal poster... i shut off, BUT i do let it idle for 3 to 5 min before i shut off. thats normaly my clean the trash out of the truck time.

I shut mine off.. because it says to on the pumps.. since we have combo diesel/gas pumps here in CA.. that and there is that new STUPID no idle law. Scott
I let it run most of the time. It barely burns any fuel and saves on wear, might as well just let it run.
