To say the development of GF-6, the next generation ILSAC category, has been a challenge is an absolute understatement. It has been the largest undertaking for any oil specification to date. This category has required the development of four replacement engine tests and three brand new engine tests while at the same time working to extend the life of existing tests until the new tests are made available. And if that isn’t enough, the efforts to introduce a supplemental category, API SN-Plus is just another thing added to the list. It has been a long struggle to get to this point, but the introduction of GF-6 is in sight. With the ACC Technical Demonstration Period coming to an end, and the BOI/VGRA Matrix moving along, has helped us realize that the API Mandatory Waiting Period is not far behind. This presentation will give an up-to-date overview of all the activities that have occurred within the past year within GF-6A, GF-6B and API SN-Plus including the proposed Pass/Fail performance limits that are currently under discussion. Wrapping it up, will include an optimistic review of the timeline.
