That's the TBN number, it's an optional add-on for more $$ per anaylsis at Blackstone. Ripped from A Quick Guide to Oil Analysis Tests :
The Total Base Number (TBN) is a measure of the reserve alkalinity in engine oils. Because acids form in the oil (sulfates and nitrates), lubricants are manufactured with a high alkaline count to counteract the acids. TBN should never be a problem if the proper lubricant change intervals are followed. If the change intervals are lengthened too much or skipped, then acids that form will consume the alkaline reserve of the lubricant and advanced corrosion of the engine parts will ensue.
