9 Sequence IV Surveillance Panel Motion The Sequence IV Surveillance Panel, having secured hardware supply, test fuel and reference oils for a test procedure that measures the performance of passenger car motor oil for low temperature engine wear, recommends to the Passenger Car Engine Oil Classification Panel, the Auto Oil Advisory Panel and the American Chemistry Council that the Sequence IVB test is ready for inclusion in ILSAC GF-6 and that the Sequence IVB procedure be published as an ASTM method. Realizing that the test parameters (AVLI and Fe content) need to be finalized and the LTMS still needs to be developed. Teri Kowalski / Ron Romano / Passed
10 Summary of Activity Since 12/7/17 Toyota solicited oil suppliers for Sequence IVB results from potential high wear oils Data from 3 oils from 3 suppliers was presented to Toyota and the Sequence IV surveillance panel 1 of the 3 oils produced high valve-train wear and very high Fe content at EOT, indicating high overall engine wear Much higher Fe versus valve-train wear than the typical valve-train wear to Fe correlation 1 of the 3 oils produced moderate valve-train wear and high Fe content at EOT, indicating high overall engine wear Much higher Fe versus valve-train wear than the typical valve-train wear to Fe correlation 1 of the 3 oils produced low valve-train wear and low Fe content at EOT, but is suspect of having formulation components that relaxed the oil degradation mechanism of the Sequence IVB test Surveillance panel action item for supplier to investigate and report back 8
11 Summary of Activity Since 12/7/17 Toyota solicited oil suppliers for Sequence IVB results from potential high wear oils Conclusions: Sequence IVB evaluates more than just the performance of a passenger car motor oil for low temperature valve-train wear, but evaluates the performance of a passenger car motor oil for low temperature engine wear Fe content is an indicator of engine wear, and is important, in addition to average intake volume loss Sequence IVB responds to a variety of passenger car motor oil formulation components 9

20 Sequence IVB Precision Matrix Analysis (n=28) Statistics Group Jan. 25, 2018
21 Executive Summary Precision Matrix (PM) Analysis Highlights: This analysis includes the results of 28 valid precision matrix tests Data supports the use of Sqrt(AVLI) transformation Significant oil differences: 1012 < 300 Lab differences are statistically significant (A < B1) Stand within Lab differences are not statistically significant Estimated within a stand test precision (r; ASTM repeatability) Sqrt(AVLI) = Estimated test precision across labs and stands (R; ASTM reproducibility) Sqrt(AVLI) = Oil means and standard deviations Target Mean AVLI Target Standard Deviation Sqrt(AVLI) Number Target Mean Oil of Tests Sqrt(AVLI)
22 PM Analysis Concerns The two high results on Oil 300 at stands B1-2 and B1-3 have large influence on discrimination between oils 300 and Without these two tests, differences between oils are not statistically significant. Discrimination is not consistent among the stands. Labs F and G may not discriminate oils Stands rank oils differently This could be an issue if the same phenomenon is observed in candidate oils Test precision is large compared to the observed range of measurements; lab differences are larger than oil differences; the high and low oils diff by 1.4 standard deviations (lowest of any GF6 test). The resulting LTMS would likely allow calibration of stands that don t discriminate oils Discriminating future oils in the test will be difficult; especially with only one test result 20
23 PM Analysis Comments - 1 Statisticians chose to weight targets by lab (25% per lab) rather than by stand (approx. 14% per stand). The effect is that the average of a lab with 3 stands and the average of a lab with 1 stand will have the same 25% weighting on the targets. This was seen by stats group to better represent industry-wide performance, align with past analyses methodology, and does not affect any results other than the targets. Stand weighted targets could be pursued if the panel desires. Some belief amongst some stat group members that transforming individual lifter results before averaging may be more appropriate than transforming the average. Since the benefit of doing this new approach was minimal and time was short, this analysis is included in the appendix only. AVLI in the LTMS file is sometimes off in the hundredths place from the calculated average of the eight lifters shown in the same file. Impact is negligible, but the source of the AVLI in the LTMS file should be made clear. 21
24 PM Analysis Comments - 2 Based on analysis conducted, there is no additional benefit in using parameters other than AVLI Additional tests could help better understand discrimination and precision of the test. Statistical analyses have not yet been completed to assess the impact of operational differences on test severity. The outcome of such analyses and discussions could ultimately affect oil targets. Given the differences noted in the surveillance panel call on January 11 th, the panel may find it helpful to review the full datafiles for all tests. 22
25 Additional Comments - 1 A review of individual lifter measurements suggests some merit to the incorporation of an outlier screening methodology An initial review of the impact of outlier screening indicates minimal improvement in oil discrimination and precision It is unknown whether or not the number of outliers for candidate oil tests are more likely to occur as compared to reference oil tests. (Greater number of outliers in candidate oils would make a stronger case for outlier screening.) Lifter bias is observed and can be taken into account in outlier screening methods Some methodologies investigated included: Removal of the max and min lifter result of both non-transformed and meancentered lifter data Weighted average with higher weights for lifters that differ Similar approach to what is done for T12 and C13 for performance properties with lifter bias Evaluating several outlier screening methods listed in E178. Outlier screening can be pursued further if the surveillance panel deems it appropriate; the final methodology will likely impact oil targets that are established using nonscreened lifter 23 measurements
26 Additional Comments - 2 An initial review of the impact of lifter weighting indicates minimal improvement in oil discrimination and precision Lifter weighting can be pursued further if an engineering reason exists for the differences by position 24
