Rotella oil for diesels is what I use. The owner's manual will specify a certain type and I'd use that.
My engine is from 1989 and not a lot of hours use, but the oil turns black after I run the engine. My diesel mechanic says that is not a problem. I changed the oil twice many years ago and saw no improvement, so I just accept that. I only use about 10 gallons of diesel fuel each year and change the oil in the Fall after a long run and the engine is hot. I pull the old oil from the bottom of the pan and change the filter each time.
