ACEA releases 2024 Oil Sequences
The European Automobile Manufacturers’ Association (ACEA) has unveiled its 2024 Oil Sequences for Heavy-Duty Engines, replacing the 2022 edition. The updated sequences reflect advancements in engine technology and the stringent regulatory requirements for pollutant emissions in heavy-duty vehicles. These new sequences are essential for ensuring that engine oils meet the performance expectations and environmental standards required by modern heavy-duty diesel engines.
The 2024 ACEA Oil Sequences introduced a new engine oil category, F01, which has specific viscosity requirements distinct from the existing E11-24 oil specifications. This addition aligns with manufacturers’ efforts to enhance fuel efficiency and meet the latest Euro VI emission standards.
Starting from 15 October 2024, oil marketers can make performance claims based on the new sequences. However, from 15 October 2025, the 2024 ACEA Oil Sequences will become mandatory for all new claims. Oils adhering to previous sequences will be phased out, and only those meeting the latest standards will remain on the market.
Heavy-duty engine manufacturers are under increasing pressure to meet stringent emissions regulations while delivering higher performance. As a result, the new ACEA Oil Sequences address both on-highway and off-highway applications, covering a wide range of fuels, including biodiesel. Notably, the F01 category aims to meet high-temperature and shear stability demands for engines using biodiesel blends.
Moreover, the sequences include tests that simulate real-world conditions, such as engine wear and soot handling, ensuring that oils perform effectively even under harsh operating environments.
With the introduction of the 2024 ACEA Oil Sequences, oil manufacturers and distributors will need to update their products and marketing claims to comply with the new standards. As engine technology continues to evolve, compliance with these sequences will be essential for maintaining engine durability and ensuring emission control systems function optimally.
These specifications are particularly important for lubricant manufacturers and marketers in Europe.
