PSA B71 2330

PSA B71 2330 is a technical specification from the PSA (Peugeot, Citroën) manufacturer for engine oils, which defines the requirements for viscosity, protective properties and compatibility with new‑generation gasoline engines. Oils that meet this specification usually have a viscosity of 5W‑30, comply with API SN/SM and ACEA A5/B5 standards, providing optimal operation of the exhaust gas cleaning system. When selecting lubricant for PSA vehicles, you should ensure that the packaging indicates “PSA B71 2330”, otherwise you risk losing warranty coverage and increasing engine wear.
