Is it necessary to run the engine to get the oil warm before draining it?
By the time I get to change my oil, the boat will have been sitting for over
a month. It seems to me that all of the oil will be in the sump and should
drain right out. If I run the engine to get the oil warm, the oil will have
to drain back down to the sump again before it can be drained.


I drain mine warm. That way most of the sediment is mixed in with the oil and
flows out of the pan. Also, the oil drains better and doesn't leave as much of
the old stuff in the pan to mix with the new.

This experience comes from changing oil and filters on my Moto Guzzi, where I
must remove the pan to change the filter.
