Shell Rotella recently launched the “What is PC-12?” Knowledge Hub, a new educational resource designed to help fleets, owner-operators, and industry professionals understand the upcoming API PC-12 diesel engine oil category. The company, which produces heavy-duty engine oils for diesel-powered trucks and equipment, developed the hub to explain how PC-12 will impact the industry as engines evolve to meet future performance and emissions requirements.

Expected to be licensed by the American Petroleum Institute (API) in January 2027, PC-12 (Proposed Category 12) will follow the current API CK-4 and FA-4 specifications. The new category will define the next generation of oil standards that will improve engine durability, efficiency, and emissions performance.

Inside the Knowledge Hub:

  • Understanding the PC-12 journey: An overview of the category development process, key milestones, and what’s next.
  • Technical insights: What performance improvements are being evaluated and how PC-12 oils will help protect next-generation diesel engines.
  • Educational content: Articles, FAQs, and expert perspectives on the evolution of heavy-duty engine oil standards.
  • Industry readiness: Guidance for fleets and drivers on planning for the transition once PC-12 is introduced.

Shell Lubricants is preparing for the PC-12 transition to ensure Shell Rotella products meet the new specifications set by API and the needs of its customers. The “What is PC-12?” Knowledge Hub will help the industry understand what’s changing, why it matters, and how to prepare.

“At Shell Lubricants, we view PC-12 not just as an update to meet changing emissions standards but as an opportunity to advance engine protection and efficiency,” said Karin Haumann, Shell OEM technical manager and chairperson of the API new category development team. “‘What is PC-12?’ underscores our continued commitment to supporting the vital people who keep our world moving.”
