ATIEL, the technical association of the European lubricants industry, has released Issue 22 of its Code of Practice, that provides guidelines for the development of engine oils that meet the latest European ACEA specifications.
As of 25 October 2021, Issue 22 of the Code of Practice supersedes Issue 21. The latter, however, remains available on the ATIEL website, for valid claims against ACEA 2016 light duty sequences, until 30 April 2022. Issue 21 remains valid for ACEA Sequences 2016 for HD engine oil. Issue 22 considers the ACEA sequence 2021 for Light Duty engine oil.
The main changes are:
• the introduction of a new VGRA Guideline for the Toyota TCD test and worked examples.
• clarification of some definitions.
• The rebranding of VGRA and BOI guidelines (with added examples) for enhanced clarity
The ATIEL Code of Practice (CoP)-in operation since 1996 – has been developed jointly by the European Automobile Manufacturers’ Association (ACEA), the Additives Technical Committee (ATC) and ATIEL. 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.
