Oiling a sewing machine is often part of its regular maintenance. Properly oiling your machine will keep it running smoothly and extend its life by preventing it from wearing out or rusting.
Identification
You should use only oil designed for sewing machines on your machine. Sewing machine oil is a white mineral oil, meaning it is clear and has no smell. The oil has a light viscosity and will not collect on the machine's gears. It is usually marketed as machine or sewing machine oil.
Warning
You shouldn't use cooking oil or automotive oil in your machine, since doing so may clog the gears and damage any fabric used in the machine. Also, 3-in-1 oil is not suitable for sewing machines, according to Threads magazine.
