I use 50wt. Motor oil. A good "rule of thumb" is: ANYtime you purchase (new) ANYthing metal, SOAK it in oil 3 days to 2 weeks to PERMEATE the material in question. I've been oiling metal items for 35 years now, so I can say, from personal experience, "It works for me".
HOWEVER, if you are wanting to preserve AN ANTIQUE: DON'T DO IT! -Get an opinion from an antique dealer as you may actually depreciate it's value.
Footnote: DO NOT SOAK THE HANDLE.
Use whatever type of oil the user manual specifies.
