1. ESCIT Ballot January 8, 2007

2. Ballot Results Sequence IIIG preferred by a majority of the members –Sequence IIIG-EOT was the preferred duration Secondary support was equally divided between: –PEI165 16 hr –TEOST MHT –Sequence IIIG at 20/40 hours Consensus vote in favor of the statement regarding SwRI’s catalyst test

3. Ballots 17 returned ballots 16 test votes cast, 1 abstention 20-hr 40-hr EOT

4. Votes by industry ILSAC members supported the Sequence IIIG-EOT uniformly. API/ACC members spread support between the three options. Labs/others supported the PEI165 or abstained.

5. Comments In support of TEOST MHT: –It is an “existing, cost-effective bench test that is appropriate for measuring phosphorus retention and/or volatility.” –It will “not negatively affect the ILSAC GF-5 timeline as the test is already in-place and monitored by the ASTM-TMC.” –It correlates with the a catalyst test which shows correlation with the field. –“Best precision and correlation” with field and catalyst data –It is an “existing bench test” and additional data can be generated quickly.

6. Comments In support of the IIIG –Using the retained phosphorus from a Sequence IIIG test after 20, 40, or 100 hours would be acceptable; the results after 100 hours are the most robust. In support of the PEI165 –“Provides the most data to correlate with field/dyno tests…” coupled with “the best precision/discrimination of all tests” considered. –A bench test that correlates engine and field data is a better path with respect to setting acceptable levels and precision of phosphorus volatility

7. Comments Other: –ESCIT should finalize test recommendation in January to ILSAC/Oil to keep GF-5 progress according to the current timeline.

8. Conclusion & Next Steps ESCIT by majority supports the Sequence IIIG-EOT. Next up: –Letter to ILSAC/Oil –Calculation method –Limits setting
