Judging by Steve D's writings in the last year or two, I would say "yes."
Steve's a big advocate of getting the engine oil to between 180 & 200 degrees. Of course this is a function of how hot the engine runs. Newer diesels seem to run hotter than the older ones, the explanation being "to get a more complete fuel burn." If you have an IR gun, it would be interesting to see what the temp is on the oil filter. After coming up to engine operating temp, of course.
