Congrats on your new machine. I know you are excited! Be sure and post a picture!
I learned in machine maint. workshop any name brand sewing machine oil is good quality. Machine oil should be very clear. If it has any yellow color toss it out. Sewing machine oil is made to evaporate, that's why a machine that uses it needs to have it replenished. If it didn't evaporate it would get old and sticky and really gum up the machine. Many vintage machines are a gummy mess because 3in1 oil was used. It's better to over oil a few drops then not oil.
