Developed by the European Association of Original Equipment Manufacturers, the ACEA sequences are a set of performance standards specifically tailored to the needs of the European market.
Engine oil must adapt as European OEMs develop new engine powertrain systems for heavy-duty vehicles that continue to improve fuel efficiency and deliver the higher performance expected from customers while also meeting the latest stringent pollutant emission requirements.
In the 2022 heavy-duty sequences, new E8 and E11 categories have been introduced to replace the now obsolete ACEA E6 and E9 categories. The E4 and E7 categories have been updated with new piston deposit tests, replacing CEC L-101-09. Claims can already be made against the new sequences as of 1 May 2022. They will become mandatory for all new claims made from 1 May 2023 onwards.
The latest ACEA Oil Sequences for light-duty engines are already in operation, having been published in April 2021. Historically, sequences for both light and heavy-duty engines were published simultaneously. However, this time publication was split to allow additional time for the development of the heavy-duty sequences.
UK independent trade body, the Verification of Lubricant Specifications (VLS), welcomes the publication of the new ACEA heavy-duty sequences. Chairman Mike Bewsey commented: “The sequences provide for a modernisation of the requirements for heavy-duty engines and corresponding engine oil specifications that bring them up to date in the market. They recognise engine developments in this critical area and align the automotive requirements with the latest heavy-duty engine emission standards. Products conforming to the new specifications will provide performance benefits to operators of heavy-duty commercial vehicles.”
