en.Wedoany.com Reported - The American Petroleum Institute (API) recently announced that the new generation PC-12 heavy-duty engine oil category has been officially approved. The introduction of this new specification provides a technical foundation for supporting future heavy-duty engine technologies and more stringent emission standards, thereby enhancing mechanical performance, equipment durability, and environmental protection. Bill O'Ryan, API's EOLCS/DEF Director, stated, "Providing the CL-4 and FB-4 service symbols now allows oil marketers to prepare for the arrival of 2027 model year vehicles and achieve a smooth transition."

This new heavy-duty engine oil category became a focal point of industry discussion at the recent annual meeting of the Technology and Maintenance Council. According to information released by API, this specification will significantly improve product oxidation resistance and enhance wear protection for hardware. Furthermore, the new category extends elastomer compatibility, improves protection for aftertreatment systems, and supports lower viscosity grades to help vehicles improve fuel economy.

Currently, oil marketers are authorized to begin finalizing formulations and preparing product packaging that meets the requirements of the new specification. The heavy-duty engine oil industry is actively responding to technological changes, supporting the green transformation of the global heavy-duty transportation sector through more advanced lubrication solutions.
