When I got my Featherweight, about a year ago, I really dreaded oiling it. There are so many places that need oil. I made a copy of the charts showing places that need oil and check off the places as I oil them. Now, I no longer dread oiling, I don't really need the charts anymore, and the process goes quickly. I oil my Featherweight once a week and change the needle at the same time. I think I sew about 8 hours a week on it as I use my Bernina quite often.
