Uhhhhhh... you forgot to mention the idling diesel.
I am one with an idling diesel. You need to keep in mind that when I pull into a campground and back my trailer in the exhaust temperature does increase to about 450*. Without idling to cool the exhaust down (time depends on how warm everything is, how hard the engine is worked prior to arriving, etc) the turbo is spinning about 10,000 rpms and shutting it down hot causes the oil flow to stop while the turbo is still spinning and the heat will cause the oil to burn (coke) around the bearings and cause a premature turbo failure. If you are next to me when I pull in I will shut the engine down soon as I arrive PROVIDED you or anyone else puts $1000 in my hand because it will cost me more than that to replace the turbo. Now, I don't let it sit and idle for hours but I also watch the pyrometer and soon as I can I shut it down.
