Standards and industrial organizations such as the American Petroleum Institute (API), the European Automobile Manufacturers' Association (ACEA), JASO (Japanese Automotive Standard Organization) and the Society of Automotive Engineers (SAE) establish specific norms to manage lubricant characteristics and performances. Each norm defines technical requirements, physical properties (such as viscosity), engine test results, and other criteria for the formulation of lubricants and oils. Our ELF lubricants comply with and follow all of the major norms, standards and classifications in effect.
