Abstract:
In response to the new advancements and stricter requirements faced by heavy-duty diesel engines, a new oil standard known as Proposed Category 12 or PC-12 is being developed. Compared to API CK-4 and FA-4, the current standards, PC-12 oils feature lower sulfated ash, phosphorus, and sulfur content, lower viscosity, and enhanced oxidation resistance to further improve fuel economy. PC-12 also supports the new regulations set by the U.S. Environmental Protection Agency, which are aimed at reducing nitrogen oxide, particulate matter, and greenhouse gas emissions, as well as extending the service life of engines and after-treatment systems. PC-12 is set to launch on January 1, 2027, aligning with the release of model year 2027 diesel engines, and introduces two distinct categories designed for both the current and the next generation of diesel engines.
