Every sewing machine, even the new computerized machines, needs to be cleaned and oiled from time to time to keep it in prime running condition. The good news is that if you can operate your sewing machine, you have enough mechanical ability to oil your sewing machine. Doing so will help your investment to sew smoothly for many years to come. The first step to oiling your sewing machine is to choose the proper kind of oil.
Some new machines come with a small container of sewing machine oil.
Some do not. Use only oil that is formulated for high speed precision machinery like your sewing machine. If you own a really expensive brand of machine, like Pfaff, New Home or Bernina, you may want to spring for the more expensive oil that you'd buy at the dealer. It is not that the oil is any better, but it doesn't hurt to have that tiny bit of insurance. The next step to oiling your sewing machine is to clean off your sewing table.
