American Petroleum Institute Releases Updated Engine Oil Licensing Certification System

The American Petroleum Institute has released an update to its Engine Oil Licensing and Certification System, as announced in a recent press release.

API’s standards are developed under its American National Standards Institute accredited process, ensuring its eligibility for third-party accreditation and allowing their use by state, federal, and some international regulators.

API 1509, Engine Oil Licensing and Certification System, provides standards for how engine oil marketers certify gasoline and diesel engine oils. The newest, 23rd edition of EOLCS provides a summary of what it is, and the methods used to develop the standards.

The new edition also includes descriptions of API Marks and their uses, along with detailed licensing requirements. It also goes over aftermarket conformance and enforcement procedures that are used to ensure products claiming to meet API standards actually do.

The 23rd edition of API 1509 is available now online.

“API 1509 plays a crucial role in managing the API Engine Oil Licensing and Certification System (EOLCS), providing oil marketers with guidelines on licensing and proper display of the API Engine Oil Quality Marks for consumers,” said Bill O’Ryan, senior manager of API EOLCS/DEF.  “The updated standard assures consumers that API certified engine oils are the highest quality option for their vehicles.”
