North American Specification Update A check into the current spec status By Joan Evans Significant progress has been made in moving some of the test developments for ILSAC GF-6 forward. However, the seven new tests are at different points in their development paths. Highlights Supplemental category ILSAC delivered a letter to API stating the need for protection against Low Speed Pre-Ignition (LSPI) for new engines being introduced into the market. Because of the delays to ILSAC GF-6, original equipment manufacturers (OEMs) are requesting a supplement to the current API SN specification to include an LSPI test designed to protect pistons in turbocharged engines. API LG agreed to accept and progress this request. While OEMs desire Jan. 1, 2018, this date has not been agreed to by API LG. ACC and API Oil Marketers need to review the supplement description and timing required for the steps to deliver the API SN Plus supplement - with which ILSAC GF-5 can also be claimed. No first allowable use date for ILSAC GF-6 Auto/Oil Advisory Panel (AOAP) waiting for a clearer picture of test development completion. BOI/VGRA A set of matrix designs has been recommended to establish read across in the Sequence IIIH, IVB, VH, VIE, LSPI and Chain Wear tests. The MOA is out for final review and signature. 24 NOVEMBER 2017 | COMPOUNDINGS | ILMA.ORGhttp://www.ILMA.ORG
