ACEA B3

ACEA B3 is a specification developed by the European Association of Engine Manufacturers for high‑power diesel engines that operate under heavy load and require long oil change intervals. Oils that meet B3 must provide high oxidation resistance, effective wear protection at elevated temperatures, and control of deposits in the combustion chamber, supporting the stability of turbocharged systems. The standard also ensures compatibility with exhaust after‑treatment systems, in particular DPF and SCR, thanks to a low SAPS content that prevents their fouling. This classification is suitable for passenger and light commercial diesel engines, including turbocharged and direct‑injection models that are commonly found in vehicles from Volkswagen, BMW, Mercedes‑Benz and others. When choosing an XENUM oil that carries ACEA B3, you get a product that simultaneously meets the requirements of B4 and C3, allowing you to safely upgrade protection without voiding warranty conditions.
