1 Auto-Oil Advisory Panel Voice Vote Form 10-DEC

2 Motion 1 The Chrysler Oxidation and Deposit test is accepted into GF-6 for evaluating the performance of engine oils for pvis and WPD contingent upon ASTM PCEOCP accepting the test procedure. Motion by: Saad Abouzahr Second: Thom Smith 7

3 Voice Vote Results Motion 1 Yes No Abstain Not Present = Auto Oil Voting is balanced or weighted to ensure ratios of 50 percent Auto and 50 percent Oil. Two-thirds of Auto and two-thirds of Oil votes cast, less waives, are affirmative. Fifty percent of all possible votes are affirmative on each side. 11

14 Stats Group Analysis A HUGE thank you to Jo Martinez, Kevin O Malley and the entire stats group for an expedited analysis of the matrix data. Slide 11

15 Summary The Chrysler test results show repeatability, reproducibility, and discrimination on PVIS, WPD, MRV, and Phosphorus Retention. The precision matrix performed similarly to the prove-out matrix as expected. The Chrysler test meets the test development objectives Status Criteria Remark Yes Stand to stand repeatability Demonstrated Yes Discrimination Demonstrated Yes 0W-16 viable Demonstrated Yes Field Correlation REO 2/3 Yes Yes Yes Procedure and final hardware available and released Long term engine supply and readiness Lab to lab reproducibility and prove-out and precision matrix 90 hours, 6 oz oil addition every 20 hours 3800 engines to last through 2022, other parts through CPD 2 independent labs and 3 dependent labs

16 Continual Improvement There are ongoing efforts by the Task Force to continue to minimize potential variables between labs in areas of honing, engine build and understand any remaining lab differences. These efforts are expected to continue throughout the test acceptance process, and beyond through the Sequence III Surveillance Panel. Slide 13

18 Viscosity Increase (%) Following the Oil Thickening Process IIIG Viscosity Increase Process ~220 % ~120 % Test Time (hrs) Oil Thickening process has 2 stages: 1. Linear increase due to volatility 2. Exponential increase due to oxidation

19 Differences between the IIIG and IIIH IIIG and IIIH tests on same oil with similar final result (162 and 167 %) IIIG IIIH Linear period is extended in the IIIH with a smaller initial slope due to less volatility.

20 Differences between the IIIG and IIIH Separating these two tests to see the differences we get: IIIG IIIH % % % % Exponential increase starts later with a steeper slope in the IIIH.

21 Additional Results From Both Tests More results on each test shows the trends to be typical. Decreased volatility with increased oxidation in the IIIH over the IIIG Further supported by ROBO results showing 48% / 37% volatility in IIIG/IIIH IIIG IIIH

22 Viscosity Increase (%) Viscosity Increase (%) TMC 438 Performance in IIIG and IIIH IIIG has a different chemistry strategy. The IIIG does not break this oil due to its reduced ability to oxidize the oil Test Time (hrs) 250 IIIH is shifted borderline severe in the IIIH and breaks in 36% of precision matrix tests. Relative to the IIIG these would be false negatives Test Time (hrs)

23 Theoretical Limit Possibilities Passing IIIH Passing IIIG Borderline IIIH Borderline in IIIG Failing IIIH?? Setting the limit anywhere between 50 to 100% preserves the intended separation of oils. LnPVIS, RMSE Overall IIIH IIIG n/a * ** * 438 **434

24 Task Force Recommendation On October 23, 2015 the IIIH Task Force voted on the following motion: The Task Force as a technical group has vetted the precision matrix data reported to date, and determined the tests included are operationally valid. Based on the matrix data the test is capable of measuring PVis and WPD. We recommend to the Surveillance Panel that the matrix data be used to consider the test to be used as an ASTM standardized test. The motion passed with 9 approves and 3 waives. Slide 21

25 PCEOP Recommendation On December 8, 2015 the PCEOP voted on the following motion: Chrysler Oxidation and Deposit precision matrix results show repeatability, reproducibility, and discrimination on PVIS and WPD. The test is suitable for measuring PVIS and WPD of engine oils, and is ready to be fully developed as an ASTM method by the Sequence III Surveillance Panel. The motion passed with broad consensus. Slide 22

26 Motion The Chrysler Oxidation and Deposit test is accepted into GF-6 for evaluating the performance of engine oils for pvis; WPD; MRV; and Phosphorus Retention. The surveillance panel will now monitor and control the test and work on further precision improvements and aligning lab D results with the other precision matrix laboratories /10/2015

33 Comparison of 438 in IIIG/H IIIG The IIIH is more severe on oxidative thickening with less volatility. Bimodal response is due less to the magnitude of the more severe results than to lower mild results than.
