ACEA requires that any claims for Oil performance to meet these
sequences must be based on credible data and controlled tests
in accredited test laboratories.

All engine performance testing used to support a claim of compliance with these ACEA sequences must be generated according to the European Engine Lubricants Quality Management System (EELQMS). This system, which is described in the ATIEL Code of Practice2, addresses product development testing and product performance documentation, and involves the registration of all candidate and reference oil testing and
defines the compliance process. Compliance with the ATIEL Code of Practice is mandatory for any claim to meet the requirements of 2007 issue of these ACEA sequences.

First allowable use means that claims cannot be made against
the specification before the date indicated.

New claims by means that from this date all claims for new oil
formulations must be according to the latest ACEA release. (For example until 28th of February 2008, oil marketers can claim engine oils meeting the ACEA 2004 release even though the 2007 release is active. After 28th of February 2008, any new oil claims must be according to the ACEA 2007 sequences).

Withdrawn means that no claims can be made against the issue
after the date indicated.

The marketer of an oil claiming to meet ACEA performance requirements is responsible for all aspects of product liability. Where limits are shown relative to a reference oil, then these must be compared to the last valid Reference Result on that test stand prior to the candidate and using the same hardware. Further details will be in the ATIEL Code of Practice.
Where claims are made that Oil performance meets the requirements of the ACEA sequences (e.g. product literature, packaging, labels) they must specify the ACEA Class and Category (see Nomenclature & ACEA Process for definitions). The categories A2 and B2 are not included in this edition of the ACEA European Oil Sequences because they are unsuitable for some of the current engines and will be unsuitable for many future
engines. Misuse may cause engine damage. However, the use of A2 and B2 oils for older engines (where owner’s or workshop’s literature recommends this use) is still appropriate and can be done according to the categories A2-96 Issue 3 and B2-98 Issue 2.
