To: API Lubricants Group Cc: Lubricants Group Mailing List API Lubricants Group eBallot on Revised Seq. IIIH to Seq. IIIG Equivalency in ILSAC GF-5 At the May 10, 2017 Lubricants Group meeting a revision to Seq. IIIH to Seq. IIIG Equivalency in ILSAC GF-5 was considered. All available Seq. IIIH to Seq. IIIG data (original and new) was reviewed. After open discussion including representative from OEMs, Oil Marketers and Additive Companies a motion was made to ballot the Revised Seq. IIIH to Seq. IIIG Equivalency Limits for ILSAC GF-5. The following LG Ballot motion was made:

Sequence IIIH is acceptable for inclusion as an alternate to the Sequence IIIG in ILSAC GF-5 with the following limits:

• pVis = 150 % max. • WPD = 3.7 min. • No Hot Stuck Rings

Sequence IIIH Limit Data

Lubricants Group Meeting

Lubrizol Data from Ballot

Summary of the data presented to ILSAC: • IIIH is more severe than IIIG particularly on WPD for GF-

5 oils• Base oils meeting the STM (based on 16 oils) blended

with this GF-5 Technology should give 4.2 WPD/65% PVIS in the Seq IIIG

• A formulation using the same technology & meeting the STM requirements was repeated 5 times in the IIIH at multiple labs. This oil averaged 3.4 WPD/ 1210% PVIS in the IIIH.

Summary

Multiple Afton results indicate RO 434-2 better represents how ILSAC GF-5 formulations behave in Seq IIIH Afton data agrees very well with statistical analysis on RO 434

RO 438-1 is known to behave differently in IIIH than IIIG PVIS is consistently low in IIIG yet varies in IIIH, depending on

when the sample breaks

WPD is occasionally very mild, depending on PVIS

Results strongly support IIIH Equivalency at 3.7 WPD
