The American Petroleum Institute (API) recently issued an updated standard that governs how marketers of engine oil certify that gasoline and diesel engine oils meet API’s stringent performance standards.
“This new standard helps to ensure consumers have the peace of mind that they’re putting the highest-quality engine oils in their cars or trucks,” said Kevin Ferrick, director, API product programs.
The 18th edition of API 1509, Engine Oil Licensing and Certification System, describes the voluntary API Engine Oil Licensing and Certification System as well as methods for developing new engine-oil performance standards. It also provides sellers with a description of the API marks and their use, licensing requirements and aftermarket conformance and enforcement procedures that help to ensure that products licensed as or claiming to meet API standards actually do meet the standards.
The 18th version of API 1509 is available here.
