A Synthetic virgin sample with a higher ad pack would mean it is a lower group oil (more by %) and they just added stuff to make it meet certification requirements? I'm talking off the shelf oils, not posh oils.
For example, O'reilly full syn has a stronger ad package than Mobil 1 syn. Virgin oil samples from Blackstone.
