The American Petroleum Institute (API) has approved two new diesel engine oil standards, API Service Categories CK-4 and FA-4.
These new categories resulted from years of collaborative effort between API’s Lubricants Group, the Truck & Engine Manufacturers Association (EMA) and the American Chemistry Council (ACC).
“API has established engine oil quality standards since the 1940s, and these new standards are intended to help protect today and tomorrow’s diesel engines,” said Kevin Ferrick, API senior manager of training and certifications. “Our new engine oil standards are developed to protect engines, meet new government regulations, and ensure engine oil performance.”
These new service categories improve upon existing standards by providing enhanced protection against oil oxidation and protection against engine wear, particulate filter blocking, piston deposits, and degradation of low- and high-temperature properties.
API is now preparing to license engine oils against these new standards. Several items related to licensing are worth noting:
