I think I can defend that practically and theoretically. I would suspect
that you will find the shutdown and startup phases of a machine to be orders
of magnitude less reliable than the smooth running phases. This is driven
by transients - temperature, shock, electrical and others that occur on
cycling up or down. There are as well systems that are used only coming up
or going down. Copiers run in single copy mode for instances were a factor
of more than 10 x more unreliable than very similar machines run flat out as
computer printers.
Practically I have had boats die on a half dozen different occasions when
shut down or throttled back. Many of these were "rent a boats" which are
often much less reliable then better maintained personal boats.
While I do not consider it a huge risk I would avoid shutting down and
changing oil at sea.
