THE NEXT CATEGORY OF HEAVY DUTY ENGINE OILS EXPLAINED
On December 1, 2016, two new categories of oil standards will be licensed: API CK-4 and FA-4. In the development phase, these oils have been referred to as PC-11A and PC-11B respectively.
Both deliver superior performance over current oils. The first will protect new and older engine models. And, the latter was designed to provide optimized fuel economy for 2017 engines that are designed to take advantage of these improvements.
In the months leading up to the licensing of API CK-4 and FA-4, new information will become available. Bookmark this site, and return regularly for ongoing updates.
