Good progress on ILSAC GF-6
Turning to ILSAC GF-6, we also see some good progress. The Sequence VIE and VH appear to be close to being approved and being ready for precision matrix work. Although in the case of the VH, precision matrix testing could be delayed if a new Sequence V fuel batch is not approved expeditiously.
The new Sequence IIIH gets mixed reviews. The majority of stakeholders have confirmed the need for this new ASTM test, but the surveillance panel has noted several technical concerns that must be resolved before moving to the precision matrix. In support the Sequence IIIH development and hardware procurement, the IIIH received a unanimous vote of “fit for purpose” at the recent AOAP meeting.
The new GMOD oxidation and deposit test is not ready either, and having an oxidation and piston deposit test is absolutely critical to moving ILSAC GF-6 forward. Other tests including chain wear, Sequence IVB, and LSPI appear to be making progress. The LSPI test, which may be the most critical test for ILSAC GF-6, could be ready early next year if some hardware problems are resolved.
Limits for the new tests to allow back serviceability to older categories is getting more attention as it is critical to have some of the tests available for development of older quality products. Although it is probably a little early to finalise this, it is critical for oil marketers and additive companies to have the ability to design products meeting the needs of older engines as well as the new ones.
A concern with the new Sequence IIIH test, that Infineum believes must be resolved, is that the test appears to rank previous Sequence III reference oils differently than in past versions of the test.

SAE 0W-16 licensing
A ballot was passed to allow licensing of API SN for SAE 0W-16 oils. Licensing of these oils, targeted for Japan, could begin as early as 1Q/15. Toyota has initiated a testing matrix to establish limits for SAE 0W-16 oils in the Sequence VID, which could potentially enable resource conserving to be added to these oils.
Industry has voted to amend ILSAC GF-5 so that the ‘Starburst’ cannot be used before ILSAC GF-6 FAU with SAE XW-16 grades.
Labeling and user language for oils with viscosity below SAE 0W-20 must still be defined.
SAE Technical Committee 1 has also issued a ballot to allow SAE 8 and 12 viscosity grades to be defined. SAE 4 was left off the ballot for the present time. Although it is likely that this ballot will be passed, industry has a long way to go to define the necessary specifications that will be needed to qualify oils this low in viscosity. Current tests have not been defined to handle oils below SAE 0W-16.

GM dexos1™ and 2™
The next generation dexos™ specifications have not been issued, making deployment of next generation service fill oils unlikely before at least 2016. Initial specifications may be a combination of old and new tests. The development of the GM LSPI, turbocharger deposits, aeration, fuel economy and the GMOD tests are all critical to meeting this timing. GM has indicated that a new specification will be issued before year end, and are still planning to use new dexos1™ in factory fill applications prior to YE 2015.
