Mike: Most industrial sewing machines have the oil holes marked with red paint to help you with the oiling process. Put a little sewing machine oil (don't use regular oil, if it gets on fabric it can stain) in each of the holes, and a little next to the bobbin case. Take the end plate on the left side off the machine, and look for places to oil in there also. If you do that, you should be fine.
No one lives forever, the trick is creating something that will.
