Shell Rotella Launches “What is PC-12?” Knowledge Hub

As diesel engines evolve to meet new performance demands and emissions regulations, PC-12 (Proposed Category 12) will represent the next generation of oil standards, following API CK-4 and FA-4. The new category, expected to be licensed by the American Petroleum Institute in January 2027, will set stricter requirements for durability, efficiency, and emissions performance.

Julie Wright, Shell Rotella North American Brand Manager, explained, “Shell Rotella wants to ensure fleets, owner-operators, technicians, and consumers have an easy-to-understand resource that explains what’s changing, why it matters, and how to prepare for the new engine oils. We aim to support the industry through this transition, just as we’ve done with previous category changes.”

What you’ll find in the Knowledge Hub:

• Understanding the PC-12 Journey: How category development began, key milestones, and what’s next.
• Technical Insights: The performance improvements being tested and how PC-12 oils will protect next-generation engines.
• Educational Content: Articles, FAQs, and expert insights on the evolution of heavy-duty engine oil standards.
• Industry Readiness: Guidance to help fleets and drivers plan for the transition.

Karin Haumann, Shell OEM Technical Manager and chairperson of the API New Category Development Team, noted, “We view PC-12 not just as an update to meet emissions standards, but as an opportunity to advance engine protection and efficiency. What is PC-12? underscores our commitment to supporting the people who keep our world moving.”

Shell Lubricants continues to lead in preparing for PC-12 by developing oils that exceed future API specifications and meet evolving customer needs.
