This isn't really M-B related but just an interesting diesel related question.

I was speaking with my father-in-law yesterday after he and my nephew had come back from touring the USS Ling, a WWII sub open as a museum in Hackensack, NJ. They had focused on the diesel powerplant on the sub and had gotten into a discussion with the tourguide and another guest. One of the other gentlemen claimed that large diesels - the type used in locomotives and moderate sized ships - did not use any antifreeze in the coolant since the coolant and oil often mixed. My father-in-law (and I) found this very surprising and were wondering if there were any truth to these statements.

Anyone have any ideas?

Thanks
