Reference Oil 820-2 Supply Issue
The reference oil supplier has indicated that the one additive component in question is still available, though it will be sourced from a different plant than the original versions of 820. The base oil will come from the same supplier though different cuts will be used to make the base oil. The reference oil supplier will run a T-11 on a small blend of the oil using the newly sourced additive and base oil. If it checks out OK, then the TMC will pursue a full reblend. The availability of the additive is good news for the SP, and will not require any additional action from the SP outside of the normal introduction of a reference oil reblend.

T-11 Soot at 4 and Soot at 15 Results
The question was raised as to how far back test results can be calculated/used. It was acknowledged that results can be calculated as far back as data is available, but the usability of that data is to be determined outside of the Mack SP. It was noted that data on the new rings is severity adjusted and data prior to that is not. No further action is necessary on the part of the Mack SP.

T-11A Oil Analyses
The only oil analyses required for a T-11A are soot and mrv. Any other measurements are at the discretion of the test sponsor. A T-11A is run for the purpose of generating an MRV sample. Soot at 4, 12, and 15 require a full length T-11 and cannot be obtained from just a T-11A.

T-10 to T-12 Correlation
This conversation was a continuation of yesterday's conference call. Prior to the call, Wim circulated a spreadsheet (attached) and reviewed it for the panel. General discussion followed and Wim subsequently moved that the SP recommend (Shank second) his proposed merit system to the class panel as an alternate to the T-10. After discussion, the motion passed 4 - 1 - 3. Wim and Greg will handle presenting this to the class panel.
