How often should I oil my sewing machine/serger?
With constant use, you should oil your sewing machine or serger about every 10-12 hours of use. A rule of thumb for a machine that is used less often, or used quite a bit and then left to sit for extended periods of time, is to oil it after you are through with your project, and then remember to run it every so often so that the oil is kept distributed through the machine. Of course, you never oil a computerized machine.
