DO NOT use "all purpose" oil as it is not suited for sewing machine lubrication".

Singer brand sm oil is available at Hancocks, JoAnne's, etc.

Since this machine is so new, I would think that it would not need oiling yet. I haven't found where it says "oil often". Your DIL might also check the Singer site to see if there are any further instructions.
