ACEA Sequences: Combined claims

Guidance on valid combined ACEA Category performance claims

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.

This guidance is part of ATIEL’s aim to provide more information to lubricant marketers on making valid and compliant performance claims.

Lubricants marketers, who are responsible for all aspects of product liability, should ensure that engine oils making claims are fully compliant with the limits of all the engine and laboratory tests required for each individual Category before including such claims on product packaging and literature.

Combined performance claims
Combined performance claims against two or more Categories within the ACEA Oil Sequences on the same lubricant formulation are possible where ALL the associated chemical limits and physical testing requirements can be met.

There are instances, however, where making a combined claim is either:

  • technically impossible due to conflicting demands of two or more Categories (example right), or
  • highly unlikely due to minimal overlap in physical and chemical properties required for that combination of Categories or demanding combined requirements that are unlikely to be met (eg Fuel Economy at a High Temperature High Shear of 3.5mPa.s and above).

The tables below show the potential combinations of claims that can be made against the ACEA 2016 and the ACEA 2012 European Oil Sequences. Combinations in the green boxes are possible, combinations in orange boxes are technically incompatible and so should not be made. Combinations in the grey boxes are possible, but have engine/bench tests with differing requirements or test limits making combined claims unlikely in a single formulation.

Partial and incomplete claims

The ACEA Sequences state that ALL tests must be passed in order to make a performance claim.  Therefore, a claim such as ‘C2 (without fuel economy)’ is not valid against the ACEA C2 Category and ‘C2 (without fuel economy)/C3’ is not a valid combined claim.

Marketers should also be aware that limits and specifications can change between different releases of the ACEA Oil Sequences (2008/2010/2012 etc).

ACEA 2016 Oil Sequences

Download the latest version of the ACEA Oil Sequences here.

This new update provides:
- A new revision of the ACEA sequences with the introduction of the new CEC L-107-19 test and limits (A/B and C categories) that replaces the Daimler M271 test and limits.
- An update to the ASTM D892 method (used to quantify the foaming tendency of engine oil) in respect of the applicability of test Option A (with or without the Option A sample pre-test procedure is permitted)
