AOAP Meeting Summary: February 6, 2013 — San Antonio, TX

Published February 21, 2013
The Auto-Oil Advisory Panel (AOAP) met in San Antonio on February 06, 2013 to discuss the status on ILSAC GF-6A and 6B specifications. API first licensing of ILSAC GF-6A and 6B is targeted for September 30, 2016. First licensing timing hinges on new test development with AOAP agreeing that the deadline is September 2013 for deciding if a test is in or out of ILSAC GF-6. The next AOAP meeting is scheduled for April 11, 2013.

Timing of the first licensing in 2016 may be impacted by the progress of new engine test development. While progress is steady, much work remains. By the end of 2013 the industry should have a much better idea of the actual timing for the commercial introduction of ILSAC GF-6 products.

New Engine Test Status:

  • Chrysler oxidation test is giving similar results to the Seq IIIG for weighted piston deposits, but is mild on percent of viscosity increase. Test conditions are being modified to increase severity.
  • GM oxidation test development is progressing. GM said more information should be available at the end of 2Q-2013.
  • The valve train wear test, Seq IVB, is showing promising discrimination and test development continues.
  • The Ford Seq VH test is showing good discrimination on reference oil testing. Test conditions have been able to create timing chain wear which will be part of the new test. In addition, test conditions are being refined to adjust the severity of deposits and wear.
  • Seq VIE, fuel economy test, is progressing well. Test developer states they need another two months to fine-tune the test procedure.
  • LSPI, low speed pre-ignition, test is progressing with hardware installation at the testing labs in San Antonio. Test engine is a 2012 Ford 2.0L, Eco-Boost (turbo charged), 4-cylinder. This is the same engine used in the Seq VH. Target is 3Q2013 to establish industry task force and release final procedure.

Honda reported on work they completed to verify that SAE 0W-16 viscosity grade engine oil is capable of meeting the draft ILSAC GF-6B standard. A SAE 0W-16 engine oil at 15 percent NOACK using a commercial GF-5 additive package and API Group III or Group III+ base was tested in the Seq IIIG, Seq IVA, Seq VIII, Seq VG, and Seq VID GF-5 engine tests all with passing results. Similar SAE 0W-20 engine oil was run for comparison. Honda feels that the new GF-6 tests will be similar to the GF-5 tests so their work shows that SAE 0W-16 oils should be capable of passing the draft ILSAC GF-6B spec.
