I've resurrected my old Jones sewing machine after the super duper computerised one I bought 17 months ago developed timing issues. The Jones machine was bought in 1982 and has only been serviced once, although I have hardly ever used it, to be honest. Since lockdown, I've started sewing and would like to clean up the machine but have no sewing machine oil to use on it. Can I use WD40 instead? Any info would be really helpful.
This is what failure looks like
