Mentioned in the "update on wire brushing" post, I have a 1/2 HP,
110v, Peerless motor that looks maybe 50 years old. It works fine. It
has special ports for lubrication, with little doors that open upwards
and where you just drip some lubricant. They are not grease gun
fittings, they just open up and you can add oil.

My question is, what oil and how much.

If it is a babbit bearing motor with slinger rings, you use
something like 20W or 30W oil. Probably the same with oil wick
design, although those may need to have the gummed-up oil
dissolved so the wicks can oil the bearings. You may just have
to replace the wicks with cotton shoelaces.
