    Park Plane Without Oil?

    I will be unable to fly my plane for 6-8 weeks. My plan is to change the oil and let the plane sit after flying it briefly with fresh oil and CamGuard. A friend suggested leaving it with the oil drained, he thought that might be better. I like my idea more, what say you mechanics? Thanks in advance. Glenn

    You have the better idea. Keep the oil.

    I don't think it makes any difference other than no oil might result in a major problem if you forget to fill it.

    I don't see that it matters. Oil in the sump doesn't protect any of the parts (cam, crank, cylinder bores) that are subject to rusting.

    In your climate I wouldn't be that worried about it. If you want to do it right, drain the oil and fill with preservative oil, run up to temp per Lycoming's instructions, spray some fogging oil in the cylinders, done.

    For 6 - 8 weeks you do not need preservative oil. I will suggest never ever leaving an airplane that can be started and run, empty of oil. It just takes a minor mis-communication or brain fart to create a $25000 problem. Heck, I won't leave my airplane overnight without oil in the engine. And if I do have to walk away for an hour, I put a sign on the prop and on the instrument panel "NO OIL!".

    Oil is cheap. Engines are expensive.

    Best of luck,

    Wes

    90% of the light GA airplanes is this country sit for periods longer than 6-8 weeks throughout their life.

    I would put new oil in it with the Camguard, fly it, and then let it sit without moving the prop.
