Sewing machine oil is mineral oil. I am sure that olive oil (organic) would get rancid and stink! I clean and oil all my vintage machines. You can get the "zoom spout" oiler at Joann, ect. with the notions (it's a 4 oz. bottle of sewing machine oil with a long tube that pulls out to reach into places) pretty reasonably. I use Tri-Flow oil (find it at a bike shop) which is a light machine oil with teflon so it lasts longer. Tri-flow needs to be shaken well before each use. Don't use 3-in-1 oil, it contains parafin which will harden and gum up your machine.
