Maybe that's why it was included at no charge?
In my experience, you can definitely over-oil. I over-oiled my Brother 1500 and figured it out when I opened the bobbin area and there was brown, gooey stuff on the floor of the machine's casing. You can start by oiling with every bobbin and if you have an excess, then you know to back off to every other bobbin. It doesn't hurt the machine, just makes a slight mess.
