JimH is correct, the real danger of leaving old oil in the engine over the
winter, is the acids and sludge that are in used oil.

If you wanted the ideal situation, change your oil after and before the
boating season. I for one, only change it after the season.

All you have to do is go looking to buy a used boat. It is amazing the

not keep up with routine maintenance. The other amazing thing you will

is the number of folks who change the oil in spring, rather than when
winterizing the engine(s).


Why would you want to run an engine with 6 months worth of
condensation in the oil pan?


Condensation in the oil pan? How about contaminated dirty oil sitting in
the engine for 6 months.
