PC-12 is no longer a development topic. API has confirmed formal approval of the API CL-4 and API FB-4 designations, with first licensing scheduled for January 1, 2027. For heavy duty engine oil formulators, marketers and product teams, preparation is already underway.

Join Lubrizol on August 6 at 9:00am EST US for Invisible. Proven. Explained. The Future of PC-12, an expert-led webinar designed to help technical and commercial teams understand what PC-12 requires, why existing API CK-4 and API FA-4 chemistry is not sufficient for the new hardware generation and what the qualification timeline means for commercial positioning in 2027.

What the session covers:

A technical breakdown of the PC-12 performance advances.
The emissions requirements driving the new hardware generation.
API CL-4 versus API FB-4: the two-designation structure, the HTHS differences and the fuel economy opportunity.
Field evidence: How Lubrizol has validated PC-12 technology.
The qualification and commercialization timeline: Where the window for first-wave 2027 participation sits and what needs to be in place before it closes.

This session is designed for formulators, product managers, commercial & marketing leads and technical customer support teams working in heavy duty engine oil markets.

This August 6 webinar is the first session in Invisible. Proven. Explained., Lubrizol’s expert-led digital series for the lubricant industry. Future sessions will explore additional lubricant market themes, including driveline and industrial lubrication. Details will be shared as each session is confirmed.
