Liz Cisneros, base oils technology manager at Motiva Enterprises, has been appointed chair of the American Petroleum Institute (API) Base Oil Interchange (BOI) and Viscosity Grade Read-Across (VGRA) Task Force.
The API BOI and VGRA Task Force is central to the engine oil licensing framework, evaluating technical data that support base oil interchangeability and viscosity grade read-across. These guidelines are essential to reducing redundant engine testing while ensuring compliance with OEM performance and durability standards.
Cisneros succeeds Eric W. Kalberer, Ph.D., of Shell, who has transitioned to chair of the API Lubricants Group. Kalberer replaces Darryl Purificati, senior technical advisor for OEM and automotive at Petro-Canada Lubricants, an HF Sinclair brand.
With more than 25 years of experience in the chemical and refining industries, Cisneros has led Motiva’s base oils technology efforts for the past eight years. Her work includes close collaboration with additive suppliers, lubricant marketers, and industry organizations to align base oil performance with evolving regulatory and market requirements.
Headquartered in Houston, Texas, Motiva Enterprises is a wholly owned subsidiary of Saudi Aramco. The company operates the largest base oil plant in the Western Hemisphere at its Port Arthur Manufacturing Complex in Texas, with production capacity of approximately 40,000 to 40,300 barrels per day.
