Absolutely.

Engines love that. We Do on ships all the time.......with bigger engines and means to recirc fuel tanks.

But I wouldn't do it on your boat.

Don't do it

Main reason for changing your oil is because of the products of combustion and other impurities that get into the oil. Used oil has traces of metal elements from bearings wearing and even from the castings on newer engines. These impurities in a diesel engine, when burned with fuel, end up being deposited on piston crowns and turbocharger blades. The residual bunker fuels used on diesel ships are tested for used lube oils and would be rejected if found. Due to the high costs of reclaiming used lube oils these often found their way into ship fuels.
