Introducing Phillips 66 CK-4 and FA-4 (PC-11) Heavy Duty Engine Oils
Effective December 1, 2016, two new categories of oil standards have been licensed by the American Petroleum Institute: API CK-4 and FA-4. In the development phase, these oils have been commonly referred to as Proposed Category 11 or PC-11 for short.
Why do we need new oil categories? The answer is simple. In part, it’s about fuel efficiency, specifically the mandated fuel efficiency improvements for heavy-duty diesel engines. It’s also partly due to changes to the engines themselves.
