I had a Bernina here that was like that. My fingers were sore the next day from trying to move the dials on it but it id finally loosen up too. It's really a matter of getting the oil into the part of the mechanism that's seized up and if you can't see where it goes it just compounds the problem. The main reason I suggested a synthetic is because it -shouldn't- harm the plastic/nylon whatever like a dinosaur oil could.
