Kind of like Smokey Yunick's recommendation that an engine should have 10 lbs of oil pressure for every 1000 RPM...a good rule of thumb, but not 100% accurate in all situations.
Maybe for a gasser, but not even close for a diesel. There's no way a diesel would survive pulling with 15 PSI oil pressure at 1500 RPM.
