Scottoiler (chain oiler)

[Wisedrum]

Of course z, x and o ring chains are much more resitent than industrial chains. They have an inner lubrication, that will stay for a longer time.
Outer lubrications hinder abrasive behavior of metal running on metal and rust to catch your chain. Something that is not easily to prevent during riding in rain, no matter how you or another oiler will oil the chain.
