Actually diesel engines aren't that sensitive. Certainly one should
not idle them for long periods - hours, but it does no damage to let
an engine idle while you are clearing up the lines or what ever. Ever
been into a truck stop on a winter morning and seen the lines of
Peterbilt's sitting there idling while the driver is in having
breakfast.

I've had them idle all night... not sure what the idle speed was... wasn't
in charge, just a passenger.


All that guy's post proves is that truck drivers are insensitive to their
motors, not that the diesels are insensitive to prolonged idling.
Most truck drivers, I suspect, do not have to pay the maintenance costs of
the machines they drive. They much prefer to come back to a warm cab after
breakfast..
However, it has to be said that those engines are warmed up when they
arrive at the truckstop. Idling a cold engine to warm it up is much worse
than what they are doing, stupid though it is..
