OTR diesels have very low specific output compared to a light duty diesel engine.
In defense of 30 weight oil, there are very knowledgeable members here who have run 30 in their diesels without issue. Spectacular UOAs as well.
Not every engine is the same, though. I have not and will not run a 30 in an engine spec'd for a 40 any time soon.
