After review and discussion, the LSG agreed by voice vote to Ballot “Ballot Table F-**—Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx )” into API 1509, Annex F. A copy of the Motion is included in the documentation. Draft of Annex F, “Ballot Table F-**—Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx )” is provided to show how the Seq. IX equivalency will be included in API 1509. The Analysis the Seq. IX Test data are provided to support Motion to accept “Ballot Table F-**—Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx )” into Annex F. Lubricants Group Members should use the API eBallot System to cast their vote and make comments. The eBallot Link is: http://Ballots.api.org. The Lubricants Group Member votes will be counted, and all received comments reviewed and considered before the ballot results are final. Non-Lubricants Group Members should comment on the Ballot Motion using the eBallot system. The eBallot Link is: http://Ballots.api.org. All comments on the Ballot Motion will be reviewed before the ballot results are final. This eBallot will close on March 30. All Votes and/or Comments must be received by the close date. If approved the Effective Date of the Change to API 1509 will March 15, 2018.

The matrix was not designed to estimate interaction effects and, due to, among other issues, multicollinearity concerns, interactions are not included in the regression analysis.
Correlation of BO and FO properties:
BOV100 and Finished Oil Noack are highly correlated and should not be included in the same model.
Likewise, BO VI and BO API Gp are highly correlated and should not be included in the same model.
