OPEL OV040 1547-D30

The OPEL OV040 1547‑D30 specification is an OEM approval from General Motors/Opel for diesel engine oils, intended for engines up to 2.0 L with turbocharging and a diesel particulate filter (DPF) system. Requirements include 10W‑30 viscosity, high oxidation resistance, wear and corrosion protection, and a low SAPS content, ensuring compatibility with catalysts and DPFs without fouling. Oils that meet OV040 1547‑D30 undergo testing to the GM‑LL‑B‑025 standard and guarantee stable operation across a wide temperature range, reducing fuel consumption and extending engine life. The specification is targeted at diesel power units of Opel Astra, Corsa, Insignia, Zafira and their commercial variants, including models with after‑catalyst technologies. When selecting XENUM oil, the OPEL mark on the filter automatically confirms compliance with these requirements, and newer similar approvals OV040‑1547‑G30 remain backward compatible for gasoline engines.
