When do you guys change the oil and filter.....right before winter lay-up or right before spring launch or both? My dealer says I should do a change oil and filter before lay-up and right before launch. I say just do it before winter lay-up. What do you think?

Just before lay up
Just before means that your engine has clean oil that will not work on the parts. Should run it for a little while before laying your boat up after the change to circulate the oil throughout the engine. I would guess 15 minutes would be fine. I can see no reason nor have I heard of a need to change it again the in spring.

I Have Heard This Before ...............
....... from oil manufacturers and filter manufacturers re new oil and filter in the spring. There is nothing to deteriorate the clean new oil over the winter if the engine is enclosed and dry. Regards, s/v Island Hunter

oil
hello warren, change it befor layup to remove acids and protect the bearings. no reason for a second change befor launch, any water condensation will be evaporated when the engine heats up. john

layup only
As a marine engineer, I concur with comments of others who responded. Change oil at layup. Not needed again just before launch because nothing has fouled oil during layup.

no layup
hello!!!!!!! if you're in the gulf we don't have a winter layup. I'm told change every 25 hours if you use your engine year round. Otherwise I would have to concur with the other responses; if you're not running the engine in the winter, the oil won't have contaminants or acids to a significant degree after the layup. If you just have" to change it twice a year, do it mid-season and just before layup. Bill

Thanks!
Thanks, guys! I was really doubting the service manager's recommendation of doing another change on spring launch. They're probably just trying to earn some extra income...heheh.

Oil is cheap
Engines are not. I always change the oil and filter at layup and again at launch. Always have, always will. The almost clean oil sits in the engine all winter. To remove it, you must run the engine long enough to bring the oil to operating temperature -- fifteen or twenty minutes under load. The clean oil circulates and further cleans the engine of crud you did not get out in the fall. Then you drain that not so clean anymore oil and refill with fresh oil and a new filter. Cheap insurance.

Change twice
I change the oil and filter at layup and run the engine for a short period of time. I then run it again after the layup period and change it again. There are a lot of impurities that accumulate in the oil over a layup period with temperature and humidity changes. If you want to check this out have an oil analysis done before and after layup. As Peter said oil is cheaper than an engine. BTW, what is the expertise of a " marine engineer " ?
