Rem Oil is a silicone oil. I didn't know it had any Teflon in it. It is very low viscosity. It seems to have a lot of "carrier" (solvent) that evaporates away leaving a very thin, low viscosity film. I think it is okay as a corrosion preventative on surfaces that don't get a lot of wear. I'm not so sure it's be much good on a chain. It's be way better than nothing but would probably not last too long.

Break Free LP or even CLP is a good one. It has a higher viscosity and has some Teflon in it for sure - shake before using. It'd work on a chain.
