You always want to change the engine and gearcase oil before winter. That

I agree with that, and you also eliminate the acidic combustion
products which cause corrosion of moving parts. What I don't agree
with is changing the oil after fogging. I prefer to do it first so
that I can restart the engines and circulate fresh oil throughout
before shutting down for the winter. Once you fog the engines they
don't get restarted until spring and the fresh oil from the change
would just sit there.
