Objective of Exit Ballot Exit ballot objective was to highlight preferred test(s) for further development Exit ballot objective was to highlight preferred test(s) for further development –Not intended to “eliminate” tests Given the timing constraints ESCIT faces, focus is critical to ensure success Given the timing constraints ESCIT faces, focus is critical to ensure success

Exit Ballot The exit ballot asked individual companies to categorize possible tests using the following ratings: 1. Affirm- My company strongly believes this test is a likely candidate for inclusion in the GF-5 Standard and should be the focus of further ESCIT development work. 2.Neutral- My company is neutral to further development of this test. 3.Reject- My company does not support further development of this test within the ESCIT organization and would not consider this test for addition to GF-5. Additionally, each test was ranked 1 to 12 with the lower numerical ratings equating to higher promise.

Tests Under Consideration 1.CIBA Proposed Test Method 2.Phosphorous Retention in the Sequence IV A 3.Phosphorous Retention in the Sequence VG 4.Phosphorous Retention in the Sequence VI D 5.Phosphorous Retention in the Sequence IIIG. (20 Hrs) 6.Phosphorous Retention in Sequence IIIG (EOT) 7.Phosphorous Retention in the Sequence VI B. 8.PEI PEI ROBO- Phosphorous Retention 11.Southwest Research Institute Engine Dyno Test *In addition people wrote in two additional tests – (1) Field Trial and (2) Afton Catalyst Test (both listed as a write in candidates)

Ranking The Results The following point system was used to rank the most preferred tests: The following point system was used to rank the most preferred tests: –First- fifth place recommendations all received points –Tests ranked lower than fifth did not receive any points –Tests only received points if they were labeled accept or neutral The first ranked test on any given ballot received 5 points, second received 4, third received 3, fourth received 2 and fifth received 1 point.

OEM Preferences

Some Ballot Comments PEI 165 and Sequence IIIG were the favorites PEI 165 and Sequence IIIG were the favorites PEI is preferred because it is a bench test, it shows promise and Ted works well within the ASTM process PEI is preferred because it is a bench test, it shows promise and Ted works well within the ASTM process Seq. IIIG is preferred because it is an engine test, it correlates to the field and is less likely to be tricked Seq. IIIG is preferred because it is an engine test, it correlates to the field and is less likely to be tricked There was widespread support for the Ciba test and also for the ROBO test. There was widespread support for the Ciba test and also for the ROBO test. Many groups felt strongly that the Southwest test was not a likely candidate for GF-5 but that this was a very worthwhile part of the ESCIT process Many groups felt strongly that the Southwest test was not a likely candidate for GF-5 but that this was a very worthwhile part of the ESCIT process

Possible Steps Forward Focus on PEI 165 and Seq. IIIG - 20 hrs. Focus on PEI 165 and Seq. IIIG - 20 hrs. Recommend a single company sponsor for each test (PEI 165 and Sec. IIIG 20 Hr.) Recommend a single company sponsor for each test (PEI 165 and Sec. IIIG 20 Hr.) Next meeting sponsors will be responsible to bring forth test development plans.
