This happens with every long engine run , weather you are changing the oil or not.
"Best Practice" would seem to remove it every time the oil is changed.
Or use a centrifugal bypass filter system and catch it as its formed.

I don't mean to drift the thread too much, but to your comments above, is that the reason why the Gulf Coast oil filters (long thread cellulose) are touted as being so advantageous? These passive filters seem more practical than a powered centrifugal unit on a typical small trawler.
