EGT and engine shut down
Greetings,
Since I've been out of the diesel game for awhile could someone give me some guidance on how long to let my 2012 F250 6.7 idle prior to shut down.
95% of the time I let the engine idle shut down option do its thing and let it idle for 5 minutes.
Is this overkill for commuting around town? I have never towed with the truck and mostly just drive it to work or to the store, very light use.
Thanks for the guidance.

If you are not pushing the engine hard ( No serious boost on turbo) the EGT's on these motors cools off really quick. I get off the freeway and it's a mile of surface streets to my home at 25-35 mph. By tim I get home my egts are down around 350°. And letting it idle my drop it to 300° I just don't see that 5 minutes of idle really cools it much from just an easy drive through the neighborhood.
So personally, when I get to where I'm going, I shut the truck off. Now if you live on top of the mountain and you used 20 psi of boost to get up the mountain on your way home, Then maybe the idle is warranted.

I let my EGTs (pre-turbo reading) get down to 300° or less before I shut down. Sometimes that means it idles for 30 secs, other times 1-2 mins. With the turbo failure rate I figure it's worth the fuel to cool the oil/bearings in the turbo. Maybe not necessary but it's worth it for the peace of mind, can't hurt either.

In this 101°+ heat it's taking me around 1-2 minutes to get it below 400°F on factory EGT1.
I used to shut down at 380 but I just wait until under 400 now.
Getting off the highway and driving through my subdivision, it's still 460° ish by the time I reach my driveway.
When it hits around 420, I line up and back into the garage, park, turn off air, open door and by that time it's in the 390's.
