That's a nice little machine. All machines need oil. They just tell the consumer they don't need to oil, but to bring it into the shop for a "service" occasionally -- which is cleaning and oiling and adjusting, done by the tech. I think you can take off the front plate to get in to everything that needs cleaning and oiling. Oh, and oil what's inside the left side door. I can't remember for sure, but I think this one might have a wick system inside, with a reservoir at the very top, and a hole to fill it.
