              best practice would be new oil in for storage, then new oil in again for recommisioning after lay up, used oil can leave a corrosive film on engine parts eating away at bearing surfaces/cylinder bores and cam lobes

         Yeah, I was thinking expense and for a shorter lay up I suppose - for an 18 month lay up that wouldn't be a consideration even for a tight erse like me.
