I agree thought that excessive idling isn't good. "Reducing to 10
minutes" sounds like too much to me.


Drive by any truck stop at 2AM in the cold. They idle 24/7 and only run 2
million miles between overhauls. What nonsense.


Idling a diesel engine such as in a boat means it will never warm up
to proper operating temperatures thus causing more wear.
In the case of a semi in a truck stop, there is an automatic shutter
in front of the radiator which closes down to keep the idling engine at
operating temps. They don't shut them down because in the morning they
would again be abusing a cold engine.
