Oil Change Frequency

For winter storage I usually change the oil and filter, drain the fuel and either run the engine for a minute or two before draining the fuel system until the clean oil circulates, or pull the distributor and oil pump drive and use a drill to build oil pressure and crank the engine over with plugs out to circulate oil everywhere. Then fog the engine with oil and back off the rocker arms to seal the cylinders. Cap the exhaust to keep critters out.

Circulating the fresh oil gets fresh oil to the bearings, ...
A good spring drive or warm up will burn off the condensation.

Other option I use is to start the car every couple of weeks to keep condensation down after the fall oil change. I make sure fuel bowls get filled before turning it over.
