Oiling is the piece of sewing machine care most people get advice about from someone else’s machine. A neighbor oils hers every few projects, a video shows six oiling points on a model you do not own, and somewhere in the garage there is a can of general purpose spray that looks like it would do. Two of those three will cost you a service visit.
The rules that are safe to give in general are narrow: which oil, which oils to keep away from the machine, and where to find the oiling points for your specific model. Everything else, including whether your machine should be oiled at all, is a question the manual answers and a web page cannot. This guide sticks to the part that generalizes.

Quick Answer
Which oil does a sewing machine need, and where does it go?
- Use oil sold as sewing machine oil. Singer describes its own as filtered and purified so the oil is clear, and lists it as petroleum based.
- Do not use cooking oil, general household oil, three in one type oils, or a water displacing spray such as WD-40, which is sold as a penetrant rather than a lubricant.
- Check the oiling points in your manual. Some modern machines have sealed bearings and are not owner oiled at all.
- Unplug the machine before you touch anything inside it, and stay out of the electrical side entirely.
Bottom line: the right oil is clear and specifically labeled for sewing machines, and the right places are the ones your manual names.
What Sewing Machine Oil Is
It is a thin, clear, light mineral oil made to sit between fast moving metal parts without gumming, staining fabric or attracting more lint than it has to. Singer describes its own sewing machine oil as filtered and put through a purification process that leaves it clear and clean, and lists it as petroleum based.
The clarity is not cosmetic. A colored or heavy oil that creeps out of a bearing and onto a seam leaves a mark that may not wash out of a light fabric, and a thick oil holds lint against the moving parts instead of letting it fall away. That is the whole design brief.
What to Buy
A small bottle of oil labeled for sewing machines is the entire purchase, and it lasts years. Buy the plain version rather than anything that promises extras, since additives are what make oils go sticky. Keep it upright, keep the cap on, and keep it away from heat.
The Oils to Keep Away From It
Three things end up in sewing machines that should not. Cooking oil, which turns rancid and sticky. General household or multi purpose oil, which is heavier than the machine wants and often carries additives. And water displacing spray, which is not a lubricating oil at all.
WD-40 is the one worth naming, because the can is in most houses. It is sold as a penetrating and water displacing product, not as a bearing lubricant, and spraying it into a sewing machine both fails to lubricate properly and thins whatever oil is already there. A spray also goes where you did not aim it, including onto electrical parts and into the felt pads that some machines use.
Grease Is a Separate Question
Some machines specify grease for gears rather than oil, and the two are not interchangeable. Whether yours takes grease anywhere, and which grade, is stated in the manual or by the manufacturer. If the manual does not mention grease, do not introduce it.
Where the Oil Goes, and Why We Will Not List Points
Oiling points differ by model, and that is not a technicality. Older all metal machines have many points and expect regular oiling. Many modern machines are partly self lubricating or use sealed bearings, and adding oil to them puts it somewhere it was not meant to be.
So the instruction is the same for every reader: find the maintenance section of your manual and use the points it names. Manuals for most current Singer and Brother models are available as downloads from the manufacturer if the paper copy has gone, and a dealer can identify the right one from the model number on the machine.
The One Place Most Manuals Do Agree On
The hook race area, under the bobbin, is the place most manuals that call for oiling at all will name, because it is the fastest moving part in the machine. Even there, follow your own manual for the amount and the exact point, and clean the lint out before any oil goes near it. Our maintenance guide covers the cleaning routine that comes first.
How to Apply It Without Making a Mess
Unplug the machine. Remove the needle, the presser foot, the needle plate and the bobbin so you can see what you are doing, and brush out the lint with the small brush that came with the machine before any oil is applied. Oil on top of packed lint makes a paste.
Then use one drop per point, not a squeeze. A bottle with a long fine spout puts the drop where you want it instead of running down the outside of the machine, which is the main reason people end up with oil on the next thing they sew. Turn the handwheel by hand a few times to spread it, then sew a few lines on a scrap of old fabric before going near a real project.
Cleaning Comes Before Oiling, Every Time
Lint under the needle plate is a cause of stitch problems in its own right, and Brother lists dust and lint collected there among the causes of skipped stitches. A soft brush and a small vacuum attachment do the job. Compressed air is popular and is worth avoiding, because it drives lint further into the machine rather than out of it.
Which Oil for Which Machine
The table sorts the common situations, since the answer genuinely differs between an inherited cast iron machine and a computerized one bought last year. In every row, the manual for your specific model is the authority.
| Machine | Oil situation | What to use | Watch out for |
|---|---|---|---|
| Vintage all metal machine | Designed to be oiled regularly | Clear sewing machine oil | Old hardened oil may need a service first |
| Modern mechanical machine | Often a small number of points | Clear sewing machine oil | Follow the manual, not a video |
| Modern computerized machine | Frequently sealed and not owner oiled | Usually nothing | Adding oil where none is specified |
| Serger | Model dependent, often has points | Clear sewing machine oil | Oil near the loopers can mark thread |
If your machine has started making a new noise, oil is not automatically the answer and can mask the real cause. Our guide to machines making noise covers what different sounds usually mean.
Inherited and Vintage Machines
An old machine that has stood in a loft for twenty years often has oil that has thickened into varnish, and fresh oil on top of it does very little. Those machines usually need the old residue cleaned out before new oil helps, which is a job worth paying for once rather than fighting for a month.
They are also the machines most likely to reward the effort, since a well maintained all metal machine keeps going for decades. Our guide to the vintage Singer machines covers what to look for and what to leave alone. Whatever the age, do not open the electrical side, and take anything involving wiring, the motor or the foot pedal to a technician. Our article on when to take it to a repair shop sets out where that line sits.
Frequently Asked Questions
What kind of oil do you use on a sewing machine? Oil sold specifically as sewing machine oil, which is thin and clear. Singer describes its own as filtered and purified so the oil is clear and clean, and lists it as petroleum based. Avoid cooking oil, general household oils and water displacing sprays.
Can I use WD-40 on my sewing machine? No. It is sold as a penetrating and water displacing product rather than a bearing lubricant, and it thins the proper oil already in the machine. A spray also reaches parts you did not aim at, including the electrical side.
How often should I oil my sewing machine? That depends entirely on the model, so check the maintenance section of your manual. Some machines expect regular oiling and others have sealed bearings and are not owner oiled at all. There is no general interval worth following.
Where do you put the oil? Only in the points your manual names. The hook race under the bobbin is the point most manuals that call for oiling at all will list, but the amount and the exact location differ by model. Clean the lint out first.
What if I put too much oil in? Wipe the excess away, turn the handwheel by hand to distribute what is left, and sew several lines on scrap fabric before touching a real project. Excess oil migrates and will mark light fabric long after you think it has gone.
Does oiling void the warranty? That depends on the manufacturer and on what the manual instructs, so check with the maker rather than assuming. Following the manual’s own maintenance section is the safe route, and anything beyond it is a question for the manufacturer or an authorized dealer.
The Bottom Line
Buy a small bottle of clear oil labeled for sewing machines and keep everything else away from the machine, especially cooking oil and water displacing spray. Unplug, strip the plate and the bobbin, brush the lint out, then apply one drop at each point your manual names, and test on scrap before sewing anything that matters. If the manual does not call for oiling, do not invent it. Read next: our maintenance routine and our guide to what different machine noises mean.
