Most newer machines should not be oiled at all; everything that needs oil is enclosed. In some of these machines, oil can actually damage the machine. For example, many newer machines have plastic in the bobbin case area. My older Bernina is all metal in that area and the shuttle race needs a thin coat of oil periodically; however, oil in contact with plastic can cause the plastic to deteriorate.
Especially for a newer machine, read the machine's manual and oil only if the manual specifically tells you to oil.
