1 API Lubricants Group Ballot Proposed Revisions to API 1509, 16th Edition, April 2007 PLEASE RETURN BY TO DENNIS L BACHELDER AT BachelderD@API.org, BY CLOSE OF BUSINESS JULY 11, 2011 Name: Company: Telephone/Fax: Address: A DISAPPROVE VOTE MUST INCLUDE THE (A) SPECIFIC PARAGRAPH, SECTION, OR PART THE NEGATIVE BALLOT PERTAINS TO; (B) SPECIFIC SUBSTANTIVE REASONS FOR THE NEGATIVE; AND (C) PROPOSED WORDING OR ACTION TO RESOLVE THE NEGATIVE. PLEASE ATTACH YOUR COMMENTS ON A SEPARATE SHEET OF PAPER. IF THE API LUBRICANTS GROUP APPROVES ANY OF THE CHANGES, THEY WILL BE EFFECTIVE FEBRUARY 25, 2011 OR THE DATE NOTED IN THE BALLOT ITEM, WHICHEVER COMES FIRST. Ballot Item 1: API SN, ILSAC GF-5 Elastomer Compatibility VGRA for Group I Base Stocks This ballot expands Elastomer Compatibility VGRA to include Group I Base Stocks. Data supporting the change is provided as an attachment to the ballot. Table F-14 Groups I, II and III Viscosity Read-Across: GF-5 Elastomer Compatibility Test (ASTM D 7216 Annex A2) Can Be Read-Across to: Test Run on 0W-20 0W-30 5W-20 5W-30 10W-30 10W-40 0W-20 NA X X X X X 0W-30 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 Notes: 1. X = read-across is permitted for the viscosity grades identified based on data and some applications of the technical principles approved by API BOI/VGRA Task Force and API Lubricants Committee. 2. A dash ( ) means that read-across is not permitted; NA = not applicable. 3. The data used to develop these guidelines did not include Group V Base Stock For VGRA when using Group I, Group II and/or Group III base stocks, the GF-5 Elastomer Compatibility Test (ASTM D7216 Annex A2) is not required if the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content (within the precision of the tests) of the candidate oil falls within the range of the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content of the base oils in the original passing oils (minimum two passing oils) and the DI package is unchanged.

We feel the intent of the proposal was to extend the current VGRA guideline to formulations containing Gp I base stocks; not restrict the existing Group II/III guideline. Currently for Group II & Group III base stocks, read across to viscosity grades beyond those listed in the table are permitted with bracketing based on BO Vis only. Current approved wording (for Group II & III) For viscosity grades not listed in the table above, bracketing two passing formulations for a given 1/11/2012 Page 1 of 5

3 Ballot Summary and Comments on Revision of API 1509 BOI/VGRA technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil viscosity at100 C falls within the range of the base oil viscosity at 100 C of the 2 passing formulations. While we agree that BO Saturates & BO Sulfur should be taken into account when Group I base stocks are present, we object to making the current guideline for Group II & Group III more restrictive. If approved, the wording proposed in this ballot would require Group II & Group III base stocks to meet the additional BO saturates and BO sulfur bracketing restrictions. We feel that ASTM D2007 variability on base oils with > 90% saturates is erratic and could cause undue burden when bracketing with Group II & III oils. We recommend that the wording be changed to include bracketing on Base Oil Saturates and Base Oil Sulfur only when Group I base stocks are involved. Proposed alternate wording (including Group I) For viscosity grades not listed in the table above, bracketing two passing formulations for a given technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil viscosity at100 C falls within the range of the base oil viscosity at 100 C of the 2 passing formulations for Group II and/or Group II base stocks. If Group I base stocks are used, the GF-5 Elastomer Compatibility Test (ASTM D7216 Annex A2) is not required if the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content (within the precision of the tests) of the candidate oil falls within the range of the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content of the base oils in the original passing oils (minimum two passing oils) The phrase and the DI package is unchanged was removed from the proposed wording because DI requirements for VGRA are already addressed in F.2.3 As to the examples we have no strong preference, any of the following approaches are acceptable o keep the original (with a Gp II/Gp III caveat added ) o use the new example (with a Gp I explanation) o use both examples (with explanations) o creating a new single comprehensive example (with an if Gp I is present condition) o dropping all examples the wording is clear enough & examples could lead to confusion 1/11/2012 Page 2 of 5

4 Ballot Summary and Comments on Revision of API 1509 BOI/VGRA Chevron Approve w/comments Chevron approves the proposed ballot only if the provided comments, which Chevron considers to be editorial, can be incorporated in the proposed change. Chevron believes that, as worded, the proposed new paragraph underneath Table F-14 inadvertently eliminates the flexibility previously available for Group II and Group III base stock for the viscosity grades within and outside of the table. Necessary changes to accommodate the use of Group I base stocks for VGRA in Elastomer Compatibility Test should not undermine previously accepted criteria. The simplest way to achieve this objective is to maintain the previous paragraph (January 2011 Version) and add a new paragraph for qualifying Group I use. The new combined paragraphs underneath Table F-14 could read as follows: For viscosity grades not listed in the table above, bracketing to passing formulations for a given technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil viscosity at 100 C falls within the range of the base viscosity at 100 C of the two passing formulations. Additionally, for VGRA when using Group I base stocks, the GF-5 Elastomer Compatibility Test (ASTM D7216 Annex A2) is not required if the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content (within the precision of the tests) of the candidate oil falls within the range of the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content of the base oils in the original passing oils (minimum two passing oils) and the DI package is unchanged. Shell Approve w/comments Afton Approve w/comments Does the data used to develop the VGRA comprehend the affect of dispersant VM s? In other words, should the core seal data set be run on the viscosity grade using the highest DVM treat? Afton is supportive of including Group I base oils in ILSAC GF-5 Elastomer Compatibility VGRA guidelines. We recently received input from other industry members that the proposed wording may place additional restrictions on existing guidelines pertaining to the sulfur and saturates content of Group II and Group III base oils. This was not the intent of the original proposal. Page 3 of 5 1/11/2012

5 Ballot Summary and Comments on Revision of API 1509 BOI/VGRA To remove this concern, we recommend that the wording be revised and suggest the following: Table F-14 Groups I, II, and III Viscosity Read Across: GF-5 Elastomer Compatibility Test (ASTM D7216 Annex 2A) Can Be Read-Across to: Test 0W-20 0W-30 5W-20 5W-30 10W-30 10W-40 Run on 0W-20 NA X X X X X 0W-30 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 Notes: 1. X = read-across is permitted for the viscosity grades identified based on data and some applications of the technical principles approved by API BOI/VGRA Task Force and API Lubricants Committee. 2. A dash ( ) means that read-across is not permitted; NA = not applicable. 3. The data used to develop these guidelines did not include Group V Base Stock For viscosity grades not listed in the table above where Group II and/or III are used, bracketing of two passing formulations for a given technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil viscosity at 100 C falls within the range of the base oil viscosity at 100 C of the two passing formulations. Example 1 for Extended VGRA with Group II and/or III Base oils For viscosity grades not listed in the table above where Group I base oil is present, bracketing two passing formulations for a given technology may be used to waive additional testing.

No Yes Reason BOV, BO Sats, and BO Sulfur fall within the BO Sulfur falls outside the In summary, Afton supports inclusion of GF-5 Elastomer Compatibility VGRA guidelines and proposes revised wording to avoid unintended consequences with this addition. We ask for input from other members to improve the clarity of this addition. 1/11/2012 Page 5 of 5

12 Data Exists to Support Group I Content for VGRA October Industry data indicated that Base Oil Viscosity at 100 C was key yp parameter for VGRA (last slide of ACC Analysis of GF-5 Seals for API BOI/VGRA presentation) Proposal to Expand current VGRA for D7216 Annex A2 Augment the current VGRA Table with the following: For viscosity grades not listed in the table above, bracketing two passing formulations for a given technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil C falls within the range of the base oil C of the 2 passing formulations.

14 Propose Combining BOI and VGRA Bracketing On page F-12 in January 2011 version of Appendix F, propose to replace the paragraph under Table F-14 which reads For viscosity grades not listed in the table above, bracketing two passing formulations for a given technology may be used to waive additional testing. VGRA is allowed if the candidate s base oil viscosity at 100 C falls within the range of the base oil viscosity at 100 C of the 2 passing formulations. Propose new wording For VGRA when including Group I base stocks with Group II and/or Group III base stocks, the GF-5 Elastomer Compatibility Test (ASTM D7216 Annex A2) is not required if the base oil viscosity at 100 C, base oil saturates, and base oil sulfur content (within the precision of the tests) of the candidate oil falls within the range of the base oil viscosity it at 100 C, base oil saturates, and base oil sulfur content of the base oils in the original passing matrix oils (minimum two passing matrix oils) and the DI package is unchanged.
