Lubricant producers can begin marketing two new American Petroleum Institute-licensed categories, CK-4 and FA-4. Soon to be referenced in on- and off-road diesel engine manufacturer specifications, they exhibit improved shear stability, oxidation resistance and aeration control properties against the API CJ-4 formulations they succeed. The API Lubricants Group developed the categories’ performance thresholds and testing guidelines to a) meet the varying needs of aging, new and in-service power packages; and, b) help on- and off-road engine manufacturers address more stringent regulations.
