Ok so I’ve always changed the engine oil in my Yanmar (Hunter 356) at the end of season as part of winterization. Thereby starting the next season with new oil and filter. However this year I have lost or misplaced my oil extractor. My home is 700 miles from my boat. So grabbing another extractor from home is not an option. Amazon can’t deliver to this northern location before tomorrow’s haul out. So the question; are there any sailors out there who do not change engine oil until the next season before put in? Or is that a bad idea.....
