OK, can accept the fuel mileage things....
Just watch a guy hook up his truck to a trailer.
backup....
Shutdown...
dolly down for fifth to match
startup
backunder....
shutdown.
hook up air lines and pigtail.
start up
Check connection.
shutdown.
Dolly up.
start up.
air up trailer.
shut down.
check inside trailer. Do pre-trip.
start up.
leave.
All in less than 5-7 minutes.
4 start-ups.
Seems like a lot of wasted fuel there.
fuel mileage.....overboard or ????

Lots of company trucks count idle time. But this is quite ridiculous.
MNdriver Thanks this. -
Why? Not running long enough to get hot. It isn't like he is pulling a long hill and reached down and turned the key off. And what he is doing with the trailer, the turbo is doing nothing. The engine is doing nothing more than a naturally aspirated engine.
I have seen this kind of thing going on as well. It seems really ridiculous to shut the truck off anytime during the hookup. Maybe after the hookup and one is doing all the pre trip stuff regarding the trailer. But each time you leave the seat? Oh well.MNdriver Thanks this. -
Most company trucks have an idle timer. I know Walmarts is set to 5min. My father drives for them and he can't idle the truck any longer than that, it turns itself off. At SNI back in 2003 my truck had a timer as well, but if I released the tractor brakes it would idle w/o going on the Qualcomm. Or u could just bump the idle and the shutdown would not happen.
But what u described above is just ridiculous!!!! That starter will go out very soon -
Have the distinct honor of knowing a few very good diesel mechanics in my life they told me this, turbos need lube and every time you shut the engine down the oil is regulated from pressure to keep it lubed.
Starting and stopping turbo charged diesel engines that many times as described by the OP is not good for the turbo, so I have been told by the mechanics.
No turbo charged diesel is like a naturally aspirated engine, that turbo spins as the engine runs.MNdriver Thanks this. -

Wearing is more related to corrosion caused by the chemical reaction of combustion products, such as sulfuric acid at low exhaust temperature and the composition of sodium and titanium at high exhaust temperature.
I am not talking about idle for a long period but to do as the OP post then it could not be helping anything, because so many think that a engine is simple this is what happens.
Not saying I am correct, just passing along what I was told by a few very well known diesel doctors.
