API has modified the licensing and renewal process for the Engine Oil Licensing and Certification System (EOLCS) to place it on a calendar year basis and make it consistent with API’s other certification programs. This new process is effective immediately.
Effective for 2013 renewals (licenses that expire after December 31, 2012), the volume-of-sale royalty fee for the API Engine Oil Licensing and Certification System (EOLCS) will be increased.
