1 To: Cc: API Lubricants Group Lubricants Group Mailing List API Ballot for Technical Principles for New Viscosity Grades and Read Across At the October 11, 2018 Lubricants Standards Group (LSG) Meeting the Lubricants Group reviewed the BOI/VGRA Task Force Proposal 6-Sequence X Technical Principles Read Across Table. Revised Proposal 6 establishes Table F-y Technical Principles for New Viscosity Grades and Read Across for new viscosity grades. BOI/VGRA Revised Proposal 6 is given in Attachment 1, page 4. The Motion to Ballot BOI/VGRA Revised Proposal 6 is given on Attachment 1, Page 5. Background Information can be found Attachment 1, pages After review and discussion, the LSG agreed by voice vote to Ballot Table F-y Technical Principles for New Viscosity Grades and Read Across. Motion to Ballot Proposal 6 Table F-y Technical Principles for New Viscosity Grades and Read Across Motion by: Eric Kalberer Second: Josh Frederick Voice Vote: For = 17 Against = 0 Abstain = 0 Motion Passed Page 1 of 2

5 Proposal 5: Sequence X VGRA Read Table Recommendation Add Table F.xx to Annex F Table F-xx Groups II, III and IV Viscosity Read Across: Sequence X Test Can Be Read-Across 1 to: Test Run on 0W-16 0W-20 5W-20 5W-30 10W-30 10W-40 0W-16 NA X X X X X 0W-20 X NA X X X X 5W-20 X X NA X X X 5W-30 X X X NA X X 10W-30 X X X X NA X 10W-40 X X X X X NA Note: 1. Tested formulations containing Group I and/or Group V stocks must contain an equal amount of the same base stock in the finished oil blend for application of viscosity grade read-across 2

6 Proposal 6: New VGRA Technical Principles Table Add Table F.y to Annex F Table F-y Technical Principles for New Viscosity Grades and Read Across Applies to oils with HTHS mpa s Passenger Car Motor Oils a Detergent (dispersant)- inhibitor (DI) content of the read-across viscosity grade shall be equal to or higher than that of the original viscosity grade. The increase in DI is limited to the maximum allowed by the ACC Code X b Base stock blend kinematic viscosity at 100 C of the read-across viscosity grade must be equal to or higher than that of the original viscosity grade, considering the precision of the test method NA c The viscosity modifier (VM) content of the read-across viscosity grade must be equal to or lower than that of the original viscosity grade Note 3 1. = principle is applicable; NA = not applicable. 2. New viscosity grades and associated read-across can only be added after review by the API BOI/VGRA Task Force and approval by the API Lubricants Group. 3. Viscosity Modifier content must be no more than 1.7 times higher than viscosity modifier content in the oil on which test was run 4. For dispersant-type VM, the VM content of the read-across viscosity grade must be equal to or higher than the original viscosity grade. 5. Read-across viscosity grades must contain an equal amount of the same Group V base stock (e.g., ester) in the finished oil blend if a Group V base stock is used in the original viscosity grade 3

The increase in DI is limited to the maximum allowed by the ACC Code X b Base stock blend kinematic viscosity at 100 C of the read-across viscosity grade must be equal to or higher than that of the original viscosity grade, considering the precision of the test method NA c The viscosity modifier (VM) content of the read-across viscosity grade must be equal to or lower than that of the original viscosity grade Note 3 1. = principle is applicable; NA = not applicable. 2. New viscosity grades and associated read-across can only be added after review by the API BOI/VGRA Task Force and approval by the API Lubricants Group. 3. Viscosity Modifier content must be no more than 1.7 times higher than viscosity modifier content in the oil on which the test was run because this was the highest level of VM tested in the BOI/VGRA Matrix. 4. For dispersant-type VM, the VM content of the read-across viscosity grade must be equal to or higher than the original viscosity grade. 5. Read-across viscosity grades must contain an equal amount of the same Group V base stock (e.g., ester) in the finished oil blend if a Group V base stock is used in the original viscosity grade 4
