Also for using the VIN, it is literally a copy paste thing. I have dual monitors at work, my own that I supplied along with my PC, and I have the RO pulled up on one screen. Then I copy/paste into the parts catalog. For competitive make, meaning not Ford or Mazda, I use the Omnicraft catalog we have since we stock some of those oil filters, or else use OReilly's or Autozone. If it is something where we don't have it and don't need it right away I will used IMC which is owned by Parts Authority, since they have a wider selection of filter brands. This is especially helpful when people bring Euro cars to us for service.
