All machines need oil. The manufacturers of the new machines just make it difficult for you to do. If you can keep the bobbin area clean and oiled, that will make a big difference. The upper shaft sometimes has a little circle plug that you can pop out of the top cover to oil that area. You can also oil the take-up area, which is just above the needle. You don't have to open the machine to oil that area, just poke the end of the oiler through the slot in the front, and oil all of the joints.
