It could be the oil just needed time to soak in. Most problems with sewing machines are operator error. I had one yesterday I thought was operator error. I was trying to sew on a Davis Vertical Feed, a late 1800's long bobbin. It just made knots. I finally figured out it had a bent bobbin carrier. The back end of the shuttle didn't seat so thread was going in the slots, pulling up and making a big mess down under. I kept retreading thinking it was user error. Finally I watched it make a stitch. And process of eliminating everything else figured the carrier was bent.
