The European Automobile Manufacturers’ Association (ACEA) has officially introduced its 2024 Oil Sequences for Heavy-Duty Engines, which serve as a successor to the 2022 edition. This latest set of sequences has been developed in response to the rapid advancements in engine technology, as well as the increasingly stringent regulatory requirements for pollutant emissions that govern heavy-duty vehicles. These updated sequences play a vital role in guaranteeing that engine oils not only meet the rigorous performance expectations but also adhere to environmental standards that are necessary for the operation of modern heavy-duty diesel engines.
ACEA members that manufacture heavy-duty vehicles are developing new engine powertrain systems to continue to improve fuel efficiency and deliver the higher performance expected from customers, while also meeting the latest stringent pollutant emission requirements. A new engine oil category F01 is introduced, which has specific viscosity requirements in comparison to E11-24 oil specifications.
Significant Changes
Among the significant changes in the 2024 ACEA Oil Sequences is the introduction of a new engine oil category designated as F01. This category comes with specific viscosity requirements that set it apart from the existing E11-24 oil specifications. The creation of this category reflects ongoing efforts by manufacturers to improve fuel efficiency while simultaneously complying with the latest Euro VI emission standards, which are designed to further reduce harmful emissions from heavy-duty vehicles.
The new ACEA Oil Sequences have been specifically designed to address the needs of both on-highway and off-highway applications. They cover a broad spectrum of fuel options, including biodiesel, aligning with the industry’s shift toward more sustainable fuel sources. Additionally, the new sequences feature comprehensive testing protocols that simulate real-world operating conditions. These tests assess various factors such as engine wear and soot handling capabilities, which are critical for ensuring that oils remain effective even in harsh and challenging environments where heavy-duty engines often operate.
From October 15, 2024, oil marketers can make performance claims based on these sequences, which will become mandatory by October 15, 2025.
