change all oils at the end of the season for winter lay up. This is written in all marine engine manuals and most owner manuals. .

while winterizing...... get the contaminates out of the engine

I've seen holes rusted in the oil pan from the inside.... Change Oil at Lay Up.

Change it after your last run, don't let the contaminants sit in there all winter and settle into the pan. Oil changes are pretty simple and quick too. You can rest easy all winter then without any concerns.

Before layup and always with 5W20 Redline!

Since you started it , lol, this begs the question, does synthetic or conventional stay clinging to parts better over long term storage.

Remember, quicker/faster flow has always been toughted as a + for synthetics.

Fresh oil.
Cheap filter.

Warm it up in the spring; and then change out the cheap filter to your nice one for the season.

Change it in the fall,add fuel stabilizer, run it to to get the oil hot and to pump the new oil into the lifters, winterize, hook the battery to some sort of maintenance charger and walk away.
In the spring, drop it in the water and turn the key.
No need to change the oil again
You really should restart the engine, because if you don't, the only engine part that gets the benefit of the new slug of additive is the top of the oil pan.

Neither , change it in the middle of winter.. This way the contaminents don`t sit there all winter and also the oil doesn`t go bad from sitting all winter!!



February 2nd sounds good.
