You sure can make a rubber motor do its stuff, so if you leave the oil on it must be OK. The silicone oil has a listed shelf life of 60 months. I've used it in heating baths and it's pretty stable. It does dissolve oxygen ( see mice immersed in it still breathing and the "Abyss" movie)and latex rubber is sensitive to oxidation. The big question is "how much does it soften the rubber?". We've all seen rubber stiffen with age under the influence of light and air. Experience would set a time and flight number limit on these motors, stored out of light. Maybe Mike Kirda could take some loops of his rubber and stretch them over some nails in a board, with and without lube, to give a "days to break" number.

Thanks for the tips

Joe
