Summary

The heavy-duty engine oil market is approaching a significant transition. Beginning January 1, 2027, the new API CL-4 and FB-4 service categories will introduce updated performance requirements designed to support the next generation of heavy-duty engines, emissions systems and operating demands.

For fleets and maintenance professionals, understanding this transition is essential to making informed lubricant decisions and preparing for changes across equipment, maintenance practices and supplier conversations. This webinar will explain what is driving the move to PC-12, how the new categories differ from API CK-4 and FA-4, and what those changes could mean for engine protection, aftertreatment-system durability, fuel economy and extended oil-drain intervals.

Attendees will also hear how the new oils are being validated through laboratory and real-world field testing and what steps fleets can take now to prepare for the January 2027 licensing date. The session will translate a complex industry specification into practical information maintenance professionals can use as they evaluate products, communicate with suppliers and plan for a smooth transition.

Attendees will learn: 

  • What is driving PC-12 and how API CL-4 and FB-4 will differ from today’s heavy-duty engine oil categories.
  • How changes in chemistry, viscosity and performance requirements are designed to support newer engines and emissions systems.
  • What fleet and maintenance teams should discuss with lubricant suppliers as they prepare for the 2027 transition.
