PSA B71 2330

Specification PSA B71 2330 is a technical approval from the French group PSA (Peugeot‑Citroën) for transmission lubricants intended exclusively for manual gearboxes. The requirements include viscosity stability over a wide temperature range (from –40 °C to +120 °C), high anti‑wear and anti‑oxidation properties, as well as compliance with the API GL‑4/ACEA A3‑B4 standard, which ensures reliable synchronizer engagement and gear protection. These approved lubricants are suitable for PSA gasoline and diesel engines installed in Peugeot 208, 308, Citroën C3, C4 models and their front‑wheel‑drive variants, where 75W‑80 or a similar viscosity is used. Since the specification does not impose requirements for SAPS, DPF or catalytic systems, it is fully compatible with any exhaust components of these vehicles. On xenum.ua the products that meet PSA B71 2330 are the transmission oil XENUM X‑TRAN 75W80 GL4/5 and the universal oil XENUM XA‑TRAN UNI, which provide long‑lasting gearbox operation without loss of performance.
