  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 EOT 40-hr 20-hr

  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

  9. Addendum • Voting Parties • RT Vanderbilt, Lubrizol, Chevron Oronite, Infineum, Afton, Phosphorus Derivatives Inc., RohMax, General Motors, Ford, Chrysler, Toyota, Nissan, Savant, Tannas, SwRI, ExxonMobil, ConocoPhillips
