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 EDT 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.

Registration will open mid-July.
