why let diesels idle for a long time?

Never owned a diesel until now. I've always seen guys let their trucks idle while they go into a store etc instead of shutting it down for however little time until they leave. Is there a reason for this?

It is to let the turbo cool down (oil cooled)

If you just run it and shut it down right away all the time, you reduce the life time of the turbo!

This is not on just diesel trucks, but applies to ALL turbo vehicles

I was told it's very bad to shut the truck right after getting off the freeway or using the motor hard. But if you drive it normally for the last few minutes you can shut it off right away.

Some people just like to leave them running, I don't. I shut mine off in the drive through. I've seen people leave their trucks idleing at the gas pumps when it clearly says "turn your motor off" on the pump. I told one guy he was supposed to shut off the motor and his reply was "that's only for gassers, diesels don't make sparks..." or something like that. I think it's just a certain type of person that does things like that.

I'm one of those idiots who leaves their truck running while pumping fuel even though I know I shouldn't... I believe that the reason they say to shut it off is because of static electricity, just like why you shouldn't get in and out while pumping. So gasser or diesel, it doesnt matter. I may be wrong but I believe that is the reason.

it's mostly so that they can feel like Cletus Snow big rig truckers in their big hoss 3/4 ton truck

there's no reason to leave the truck running to go into a store, etc.

I leave mine running while pumping fuel because I want to sit in the AC. I'll leave it running with the AC on for my dog. But just idling a truck "cuz it's a diesel" is just ignorant

cracks me up when guys leave their modern straight piped dodge sitting outside home depot running for 30 minutes like it's some wore out old 72 Mack R with an air starter or something

I also leave mine running while fueling. Main reasons are for the dog/other people in the truck, less wear on the starter, and it actually takes a significant amount of energy to start the truck, so where I can save money and wear on the truck, I do so.

Doing it "cuz it's cool" is asinine. Depending on how long i'm going to be pumping or in the store, I shut her down. And yes, the turbo ALWAYS needs to be cooled. You don't want to make that mistake.

I never said anyone was an idiot for it. Just want that clarified. It takes all kinds of people to make a world and we all have the right to be who we are.

If I see someone with kids in the truck and the windows up then I know exactly why the truck is running. The guy I confronted had nobody in the truck and the drivers door was open with music blaring. It may have been Cletus.....

If I'm going in the bank and my GF is in the truck I'll leave it running for her.

You know what!! I bet if the cletus types had a scangauge2 and could watch their exhaust temps they would know exactly when they could shut off the truck!!
