All machines need oil -- they're machines. You should be comfortable with removing your needle plate and cleaning under it. I'm assuming you have a drop-in bobbin. You can put a drop of oil in the center hole under your bobbin case, and oil the feed dogs that are usually at the front of the feed dog area. This area doesn't really need to be oiled very often -- maybe every 6 to 9 months.
These newer machines are hard to get the covers off, so it's a good idea to take it to the shop for deep cleaning. A lot of the new machines don't have service panels or doors to get inside easily. I tell my customers that if they sew every day, they need to bring the machine in at least once a year. But don't go longer than 4 or 5 years without a service.
