I have learned, since owning one, that less is best. I oil gently per instructions in my downloaded manual, about every 8 hours of use. My 'machine guy' says a drop of oil means a drop of oil. I'm going to let him lube my motor, as I take my machines in once a year for their annual checkups. Featherweights are so simple, yet so accurate in their beautiful stitches. I just finished a queen size Bonnie Hunter scrappy on mine (not the quilting though).
