Didn't get many posts on this, but here are the data.
The second column might be fill lines. "TAG" is German for "Day", too, so I don't know. Perhaps everyone didn't provide all of the alpha characters in the codes.
Significant difference in the second column identifiers might mean that the oil is filled in more than one location, too.
If anyone else with the oil cares to provide numbers, I'll update my table and repost.
If anyone has knowledge about how Castrol lots out their blends, please share.
