Designed to allow diesel engines to work longer and harder, PC-11 oils are expected to provide better protection and fuel economy compared to API CJ-4 oils currently used in heavy-duty diesel engines.

PC-11 was developed with three primary considerations:

  • Enhanced fuel economy with engines designed to run with lower viscosity fluid
  • Oxidation stability
  • Shear stability

As the 11th evolution of its kind, PC-11 is a necessary improvement, providing better protection for current engines, while making advancements in engine technology possible.

Prior to PC-11, nearly every new category has been backwards compatible. PC-11, however, will be divided into two subcategories to offer both backwards compatibility to current engines, as well as advanced chemistry for engines manufactured in the future.

API-CK4

PC-11A: Licensed as API CK-4
Offering upgraded protection for all new and older heavy-duty diesel engines.

  • Backwards compatible in applications calling for API CJ-4, CI-4 PLUS, CI-4 and CH-4
  • Traditional high-temperature, high-shear viscosity
  • Improved oxidation, shear stability and aeration performance
API-FA4

PC-11B: Licensed as API FA-4
Formulated for use in the next generation of more fuel-efficient on-highway diesel engines.

  • Reduced high-temperature, high-shear viscosity
  • Improved fuel economy in engines designed to operate with lower HTHS
  • Improved oxidation, shear stability and aeration performance
  • May be backwards compatible with some current engine models
