FWIW the "old school engine flush" is 1 part kerosene or diesel to 3 parts new oil, run until it gets warm to the touch and drain. Refill with new oil, change oil in 500 miles or 8 hours. This is what a Navy mechanic told me anyway.
Actually you are correct,diesel is kinda ok ,reminds me when I ran a smaller stern trawler my first job as chief engineer had 2 aux engines to run domestic power and winches,we swapped load every 200 hrs but they had a habit of puking injectors before service time (2K hrs) and the oil dipstick would float up and down in the tube,used to be a mad rush to change duty
.
We used to do overhaul them every 45K hours ,the bottom end bearing were always within service hours but replaced anyway.
Anyway rant over .
