Adoption of Low Viscosity Grade Engine Oils

The American Petroleum Institute (API) has formally adopted SAE 0W-8 and SAE 0W-12 viscosity grades into API Service Category SP, the most current gasoline engine oil category.

API 1509 Engine Oil Licensing and Certification System (EOLCS) which is API’s standard defining how the API Engine Oil Service Categories and Quality Marks are licensed and displayed, will be updated with the details from the September 19th passing ballot.

Adoption of SAE 0W-8 and SAE 0W-12 into API Service Category SP is a crucial step in establishing licensing requirements, aftermarket conformance, and enforcement procedures for these viscosity grades globally. These engine oil viscosity grades are currently recommended by some global original equipment manufacturers (OEMs), and this update will provide OEMs the ability to recommend API-licensed engine oils, assisting consumers in finding engine oils recommended by their vehicle manufacturer, especially in North America.  

API represents all segments of America’s natural gas and oil industry, which supports more than 11 million U.S. jobs and is backed by a growing grassroots movement of millions of Americans. Our approximately 600 members produce, process and distribute the majority of the nation’s energy, and participate in API Energy Excellence®, which is accelerating environmental and safety progress by fostering new technologies and transparent reporting. API was formed in 1919 as a standards-setting organization and has developed more than 800 standards to enhance operational and environmental safety, efficiency and sustainability.
