ACEA Sequences: Claims Representation

ATIEL provides this guidance as a service to its members. It is based upon its understanding of the ACEA Oil Sequences; only ACEA can give an authoritative interpretation.

When ACEA releases a new version of its Oil Sequences, a new year number is assigned to it. The year numbers that have been used to date are: 1996/1998/1999/2002/2004/2007/2008/2010/2012/2016.

Although more than one release may be valid at the same time, currently (from 1 December 2018) it is only the 2016 Sequences that are valid, and each new release updates the sequence content in some way, for example:

  • new class/categories (additions)
  • continuing class/categories (changes)
  • and non-continuing class/categories (deletions)

New class/categories are assigned as class/category/year suffix, eg C4-16. Continuing class/categories are assigned according to the severity of the change, eg:

  • a change in year suffix, e.g. C3-12 to C3-16
  • a new issue number, e.g. E7-08 to E7-08 Issue 2

NOTE: Year numbers and Issue numbers are intended by ACEA for industry use only. ATIEL interprets this to mean that they are not intended for use on marketing information such as product data sheets and product labels.

Non-continuing class/categories may be removed from the new releases.

Validity periods for claims
The timing for introduction of new sequences is defined in the table below;

New and continuing class/category claims for the new release can be made immediately, e.g. from 1 December 2016 for ACEA 2016. After a defined period, all newly introduced products making continuing class/category claims must be to the new release, eg from 1 December 2017 for ACEA 2016.

After a defined period, all existing products making continuing class/category claims should be to the new release and the earlier year number releases should be withdrawn, e.g. from 1 December 2017, all ACEA C4 should conform to ACEA C4-16.

Non-continuing class/categories may still be used, in which case the most recent year release should be used and the appropriate ATIEL Code of Practice issue followed.

Labelling format for making a claim
The class/category is used as the performance claim with no year suffix. Claims available for use are:

  • E1 (1998 release)
  • A1, A2, A3, A5, B1, B2, B3, B4, B5, E3.E5 (2002 release)
  • E2, (2007 release)
  • A1/B1 (2012 release)
  • A3/B3, A3/B4, A5/B5,C1, C2, C3, C4, C5, E4, E6, E7, E9 (2016 release)

Subject to the detail of each class/category specification, all claims are available for use together, e.g. a claim for A3/B4, E7 is possible. Further information can be found on the ATIEL website section on incompatible ACEA clams.

ACEA performance claims are self-certifying. No qualifying approval remarks, such as ‘certified’ or ‘recommended’ are allowed. ‘Meets ACEA …..’ is the format commonly used. When introducing or withdrawing products, it should be in accordance with the ACEA sequence timescale. The determining date is the blend date.
