    This is true, but is also why many of them develop cam/ lifter issues due to neglect.

    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:

    INACTIVE 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.

    Have not any of you folks heard of Aeroshell Fluid F fly away preservative oil? Funny, nobody has mentioned it. I recall it's good as a preservative for 3 to 6 months, and can be flown at any time with a 50 hour limit.

    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.

    If you're using two 13W LED bulbs, should they be "Bright White" or "Soft White"? :-)

    This is precisely what I recommended in post #6, although not by brand name as there are others as well. This is Lycoming's recommended procedure. I think the time limit is 10 hours not 50, but I don't have the specs in front of me.

    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.

    One just has to ensure it is aligned to the Sun properly.
