If it was used oil full of acid I could see a point to draining it. With new oil I can't see any point.
In any case, you would be wise to follow the manufacturers recommendations. In the case of Lycoming SL 180:
https://www.lycoming.com/content/ser...etter-no-l180bINACTIVE ENGINES:If it is known that an aircraft is to remain inactive for 30 or more days, the following procedure should be applied to the engine, especially if the aircraft is located near salt water or similar humid environment.
I put a pyramid on top of the engine. Never had a problem.
I think a 25 watt lightbulb in the cowl to keep it above dew point is all that is needed.
But don't heat the bottom to make steam that condenses on the cold top and cam.
Just keep it 10° above dew point.

Fresh oil, Cam Guard, run up to warm oil. Shut down and don t move prop. Any longer, i would "fog" cylinders and comply with Lycoming proceedures.
