Trends in Environmental Technology for Automobile Engine Oil

―Environmental Measures in the ILSAC Standards―

Abstract

This report introduces the environmental performance required for engine oil through the transition of ILSAC standards and the additive technology that enables it. Also, SAE J300 has gradually standardized low-viscosity oil grades that are expected to have fuel-economy characteristics, then GF-6B newly adopt 0W-16. Furthermore, JASO adopt 0W-8 as well as 0W-12. As viscosity decreasing, conflicting robust performance is also required, and further development of additive technology is expected.
