The ATIEL Industry Liaison Committee (ILC) engages with key automotive industry stakeholders on existing and emerging technical issues and trends impacting engine design and use, and their potential effects on lubricant performance and formulation. Its focus is to support the development of specifications that lead to fit–for–purpose lubricants and ensure their timely availability.

The ILC actively engages in technical discussions with automotive manufacturers, represented by the European Automobile Manufacturers’ Association (ACEA), as well as with other lubricant-related industry groups such as additive manufacturers, represented by the Additive Technical Committee (ATC).

The European Automobile Manufacturers Association (ACEA) represents the interests of major European car, truck and bus manufacturers. They set performance specifications for engine lubricants through its European Oil Sequences. ACEA performance specifications are increasingly adopted outside Europe.

With the support of ATC, the ILC formulates ATIEL’s response to the evolving ACEA sequences. Discussion are held within ACEA extended heavy-duty working group and ACEA light-duty working group every quarter.

The ILC also has direct contact with individual OEMs or other automotive groups, including component manufacturers, on specific technical topics.

In addition, ATIEL is a member of the European Coordinated Council for the development of performance test for fuels, lubricants and other fluids (CEC ). The latter is an Industry-based organisation which develops Test Methods for the performance

testing of Automotive Engine Oil, Fuels & Transmission Fluids (using gasoline & diesel engines).

CEC lubricant test methods (engine, rig and laboratory) are one of the pillars of EELQMS. Stakeholders in CEC are: ACEA, ATIEL, ATC & CONCAWE*. ASTM International also develops North American engine and laboratory tests and standards, some of which are included in the ACEA Oil Sequences.

ACEA sequences

Since their introduction in 1996 the ACEA Oil Sequences have been updated periodically to ensure that engine oils are able to meet the ever-changing requirements of the latest engine technologies. For the first time since the Sequences were first released, ACEA 2021 has separated the Light and Heavy Duty Sequences to allow a more flexible approach to updating the specifications.

ACEA Sequences 2021 for Light Duty Engine

ACEA 2021 updates the Light-Duty Sequences to replace old engine tests that have reached the end of life, to allow a continuation of the engine oil development process for vehicles already in market. The new tests run on more up to date engine hardware but allow oil marketers to continue to supply oils with proven field performance. The two new Categories published in ACEA 2021 introduce several new performance parameters and give oil marketers an opportunity to demonstrate the performance of their lubricants in the most modern vehicle technology.

ACEA Sequence 2016 remain valid for Heavy Duty Engines

ACEA Sequences 2021 Light Duty Engines – changes to categories

The two new Categories, C6 and A7/B7, for the first time introduce LSPI, timing chain wear and diesel turbocharger performance limits into the ACEA Sequences, and C6 includes a new fuel economy test.

ACEA Sequences 2021 for Light-Duty Engines– changes to Test

The addition of tests from both API (the LSPI and chain wear test) and JASO (the new fuel economy test for C6) helps to increase the global applicability of the ACEA Sequences, as well as giving oil developers the confidence of running test programs in well-established engine tests.

ATIEL members have considerable expertise and field experience that can support and inform discussions around the effects of engine design changes on lubricant performance under actual service conditions.

The ILC’s involvement in the early stages of technical developments enables ATIEL to provide useful input to the design of new specifications. This proactive approach is also important for providing the lubricants industry with the necessary lead time to develop and reformulate lubricants that will be required to meet new evolutions of the ACEA specifications. It is in the best interests of all automotive industry stakeholders, and particularly consumers, that when new specifications are introduced the appropriate lubricants are widely available across the market.
