I would go ahead and do it. I just turned it upside down and moved the parts that move the fabric through (don't know what it's called) and I could see the spring and all the hinges move and that's where I put a couple drops of oil. It worked for me. Just do as I and others have suggested and sew on scrap fabrics for a while to make sure excess oil doesn't get on thatever project you're working on. Good luck.
