Most sewing machine oil is a pure very light weight mineral oil and usually is devoid of any R&O additive. It tends to oxidize over time to a carbon based varnish. R&O is Rust and Oxidation, rust for the metal that is lubed and oxidation for the lubricant.
Clock oil is a much higher refined product and does contain additives. If it is synthetic clock oil it will last almost forever and does not creep. Spring oil is another clock item that the phono folks should pick up on. Springs in open barrels probably should be greased, use a synthetic grease or you will be doing the job again in a couple of years.
