Read the manual first, and let it decide. A great deal of advice online says to oil your machine regularly. For many machines sold in the last fifteen years that advice is actively wrong.
Sealed machines. Many current domestic machines are lubricated for life at the factory, with the lubricant where you cannot reach it. The manual will either say so or simply not mention oiling. Adding oil to one of these does not help, and it can carry lubricant to somewhere it will reach fabric.
Machines that do want oil. Older mechanical machines and most industrial and semi-industrial machines have named oiling points, and the manual lists them. On those, oiling is genuinely part of maintenance.
If your machine does take oil. Clean it thoroughly first — oil on top of lint makes a paste that does the opposite of what you intend. Use clear sewing machine oil only: household oils and penetrating lubricants gum as they age and several stain fabric permanently. One drop per named point, not a general application. Run the machine unthreaded for a minute, then sew on a scrap to catch any excess before it reaches a garment.
What most machines actually need is cleaning, not oil. Lint in the bobbin race is what stops machines working. A brush costs almost nothing and fixes more than a bottle of oil ever will.
Questions people actually ask
My manual does not mention oiling at all.
Then it does not want oil. Silence here means sealed for life, not "we forgot to say".
I already oiled a sealed machine. What now?
Run it unthreaded for a minute and sew on scrap fabric until nothing transfers. It is unlikely to have done lasting harm; just do not repeat it.
