Next winter change the oil BEFORE storing the boat.

Any acids not neutralized by the used additive package have been chewing on the engine surfaces all winter.

For me single weight still wins .

Change the oil after a long hard run ,all day if you can , while still very hot.

PIA but should do the best job of removing the fines, that work like grinding paste if not removed.
