The oil I use in a McCulloch CS 380 (18 inch rail), a Jonsered 2234 (15 inch rail) and a Rancher 460 (24-inch rail).
The canister has a 5 cm long gooseneck for easy oil filling. But I have a jerrycan of Oregon with this mixture and oil in another container. So you hold it for a while in the forest without being too tight with lubricants or fuel.
The oil is recommended uneingschränkt.
