Code of

Atiel Code of Practice

ATIEL is committed to supporting the development, marketing and manufacturing of automotive engine lubricants that fully satisfy the European performance and quality requirements deemed necessary by the European Automobile Manufacturers’ Association (ACEA) for satisfactory engine life and operation.

The ATIEL Code of Practice (CoP) forms an integral part of the European Engine Lubricant Quality Management System (EELQMS) that has been developed jointly by the European Automobile Manufacturers’ Association (ACEA), the Additive Technical Committee (ATC) and ATIEL.

The EELQMS is an overarching quality management system (QMS) that embraces various standards, test methods and procedures, Codes of Practice and the ACEA Oil Sequences requirements.

The purpose of this Code is to provide a mechanism and a basis for commitment to standardise practices when developing, marketing, or manufacturing engine lubricants for which compliance with the ACEA Oil Sequences is claimed.

The ATIEL Code of Practice has been in operation since 1996 and has made a significant contribution to testing and product quality levels for engine lubricants. The Code is available to all companies on a voluntary basis and nothing in the Code forms part of a contract.

ATIEL published the 24th issue of the Code of Practice in January 2024.
