I have Babylock machines and you don't oil them, you can void your waranty if you do. As for needles I throw mine away after using, I feel that once I've changed a needle its "goodness" is gone. I really don't see a need to keep a used needle unless you changed it out to change to another size and it's still got its "goodness". If a well used needle can be recycled for something else, I would like to know. I'm all for recycling. :lol: :wink:
