ACEA B1

ACEA B1 code is a specification for high‑performance gasoline engines, including turbocharged and direct‑injection units, which require low viscosity and high fuel efficiency. The standard mandates a minimal content of sulfate, aromatic and phosphorus compounds (SAPS), ensuring long‑lasting catalyst operation and preventing their deposits, as well as guaranteeing oxidation stability at high temperatures and wear protection. Oils that meet ACEA B1 are suitable for modern gasoline powertrains with turbocharging, direct injection and start‑stop systems, including passenger‑car and crossover models. When choosing on xenum.ua you can consider products such as XENUM SEMIX 0W20 or 5W20, which have been tested to this code. If a slightly higher level of protection is needed, newer specifications ACEA A5, A7, B5, B7, B3 and B4 are compatible and remain backward compatible without risk of engine damage.
