See if this works with your machine
SEW-RETRO Grease™ has been specially formulated with the proper melting point and lubricating qualities for vintage & antique sewing machines, including the Singer Featherweight 221 & 222K... some attachments need grease sometimes, too! SEW-RETRO GreaseTM is appropriate for any and all sewing machines with all-metal gears. (Do not use this lube with any plastic or nylon gears.) SEW-RETRO GreaseTM is appropriate for other vintage Singer Sewing Machine motors - so long as the vintage Singer motor has motor ports with a felt wick inside. If you are unsure of this, then if your manual indicates that your vintage Singer motor requires motor lubricant, then SEW-RETRO Grease™ will be perfectly suited for your machine. Each SEW- RETRO Grease™ comes with an instruction sheet for application as well as a port-cleaning tool so you can clean out the motor ports of the old grease. Keep out of reach of children, and do not ingest.
