API Shares Update on Development of ILSAC GF-8

The American Petroleum Institute this week provided an update on the development of the next car engine oil category—ILSAC GF-8.

Progress toward GF-8 continues, with stakeholders reaffirming a target launch of the third quarter of 2028, contingent on successful completion of key engine test developments. ILSAC has accepted many proposed technical updates following recent Auto Oil Advisory Panel discussions.

Development of the new Sequence VJ sludge test, which will replace the Sequence VH sludge test, is advancing through multi-lab prove-out testing. Meanwhile, a task force responsible for fuel economy test development is working to extend the life and precision of existing Sequence VIE and VIF tests.

Although many of the task force’s recommendations were accepted by ILSAC, further refinement and validation remain necessary before final implementation, API said in a statement.
