I wondered that too. The port fits the end of the tube of Singer Motor Grease. The original tubes had a lead (or lead like) tip that fits into that port sealing most of the leaking. The grease is light weight, and will wick into the bushing/bearing at the end of the motor, and motor heat will help this to keep grease in place. This is why the manual says every 6 months. Oil would be too light, and the bearing would end up dry.
Most of the motor grease ports I have found on sewing machines look like this. My mother's 221 came with a tube of original Singer motor and gear grease in one of those tubes, and the port looks just like the one in my 301.
