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.

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.






With every used boat we looked at each time we went up or down in boat size,
the first 2 questions would be:

1. Can I see the boat maintenance log or a copy of your receipts showing
the maintenance work done?

If none, I walked away.

2. How often and when do you change the oil?

If the answer was "in Spring only", I walked away.

2 simple questions that told me a whole lot about the boat maintenance.
