Bob Olree of General Motors, who chaired the ILSAC/Oil Committee that shepherded the GF-4 passenger car engine oil specification to approval, is signaling that work toward the next upgrade – GF-5 – may soon get under way. The GF-4 specification was approved on Jan. 14 and begins licensing under the American Petroleum Institute on July 31.
At its semiannual gathering last month in Salt Lake City, Olree advised ASTM Committee D-2 that he and his auto industry colleagues who comprise ILSAC (the International Lubricant Standardization and Approval Committee) are only in the pre-discussion stage on GF-5. However, he declared, GF-5s target implementation date is 2009. Hence a meeting will be held shortly to review the approval process for GF-4 under ILSAC/Oil, and see where it needs to be tweaked to make it more efficient.
