PC-11 to CK-4?

Tulsa, OK - PC-11 is now moving quickly towards first available use with most API test issues resolved. December 1, 2016 now seems to be the firm date for the release of this new specification. That is only 8 months after the initial target date of April, 1 2016. The new Volvo T-13 and CAT engine specifications were part of the hold up, that has been resolved. No timetable has been set for the PC-11A and PC-11B specification on high and low shear oils. The new categories will be API CK-4 and FA-4.
