Votes by industry
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.


Comments
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.


Comments1
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


Comments2
Comments

  • Other:

    • ESCIT should finalize test recommendation in January to ILSAC/Oil to keep GF-5 progress according to the current timeline.
