There is a LOT of disagreement on just how much damage is done by Wet Stacking / Diesel Slobbering and not running an engine under load etc. You can find studies done by the US Army that indicate little if any damage is incurred, quite to the contrary of what most of us shade tree mechanics think. Army has many thousands of Diesels that are not often run and put under a load, but sit in motor
pools and if they are lucky, get run a little on a weekly basis or just sit.
Many, many years ago US Army went to SOAP or spectrographic oil
analysis program, now it's not uncommon at all for an engine to not get it's oil
changed for years, cause oil change
only happens when the SOAP says to, another Sin to us shade tree types.
I run an engine hard every so often as I believe it's good to do so, but only for a short while, and not all that often.
I don't run it at 80% power continuously, mostly cause I can't stand the noise
, but if you can, and want to, it should handle it. Above 2000 RPM and the thing just grates on my nerves.
I don't think percent power follows RPM all that well, I bet the last 25% power is actually in a pretty narrow range of RPM, for example I believe my 4-JHE is 44 HP at 3600, and drops 10% to 40 HP in only 100 RPM to 40 at 3500, and I bet drops another 10% in another 100 or maybe 200 RPM.
