Subject:	Minutes of T-11 June 4, 2003 Teleconference
Here are the unapproved minutes of the Mack T-11 Task Force Teleconference of June 4, 2003.

Participants:
Jeff Clark - TMC; Steve Kennedy, Riccardo Conti - ExxonMobil; Michael Minotti, Pat Fetterman - Infineum; Bob Campbell, Charlie Passut - Ethyl; Jim Moritz, Joe Franklin - PerkinElmer; Scott Richards - SwRI; Greg Shank, Ken Goshorn - Mack; Jim Matasic, Herman George, Gita Krishnaswamy, Mark Rees - Lubrizol; Jim Rutherford, Wim van Dam, Mark Cooper - Oronite; Ron Buck - TEI

Summary of Action Items:
1. Jeff Clark to provide the reference oil quantity remaining for oil 820-2
2. Labs to continue submitting data
3. Jim Rutherford to continue analysis

Stand Instrumentation Calibration
A motion (Campbell, Richards) was approved that specifies stand instrumentation calibration be performed at a minimum, at rebuild or 9 months, which ever comes first. The motion passed unanimously.

Lab Visitation
There will be O&H lab visitation at Ethyl on Tuesday, June 17th for 10 am.

Review of Data
Jim Rutherford's presentations are attached (Two dated June 2, one June 3). Jim's assessment is that once a measure has been selected, the question is at what soot level is that measure reached. Rate Index itself does not appear to be a good p/f criterion. That leaves absolute vis, relative vis, and rotational vis. The absolute kinematic viscosity appears to be the most promising. The one piece of the puzzle we don't have yet is what happens on other oils. Greg desired narrowing down to two or three possibilities for p/f parameters. After much discussion, it was decided that we still need more data to make any further decisions. The soot range of interest may determine which measure is best. Greg indicated 6% soot is the area of interest. After much more discussion, it was decided that we didn't have enough information to eliminate any of the remaining possible parameters. Jim was asked to look at linear interpolation around 6% soot. For relative viscosity, 0.88 x DIN Shear viscosity will be used as the denominator. Discussion continued for quite some time.

Future Meetings

Conference Call: Wednesday, June 11, 10:30 am Eastern.
