GM LL-B-025

GM LL‑B‑025 is a motor oil specification developed by General Motors for gasoline V6, V8 and inline four‑cylinder engines, including turbocharged ones, installed in passenger and light commercial models. It requires viscosities 5W‑30, 5W‑40, 10W‑30 or 10W‑40, meets API SN/SM and ILSAC GF‑5 requirements, and also a low SAPS content, providing catalyst protection and, when needed, DPF system protection. The specification is targeted at engines operating over a wide range of temperatures and loads, ensuring a stable lubricating film, reduced wear and oxidation control. XENUM products approved for GM LL‑B‑025 include SEMIX 5W40, NIPPON Runner 5W30 and SEMIX 5W30, and they remain compatible with newer GM specifications such as DEXOS 2 without losing warranty compliance. By choosing oil with this approval, technicians and drivers gain confidence in engine durability and performance.
