10W-30

The designation 10W‑30 according to the SAE J300 standard indicates a cold viscosity of 10 W (the oil’s ability to remain fluid down to –30 °C) and a viscosity of 30 cSt at 100 °C, providing quick start‑up and stable protection during engine operation. This grade is suitable for gasoline and diesel engines of passenger cars as well as for medium‑heavy trucks operating in moderate and cold climatic conditions. 10W‑30 oil is compatible with catalysts and emission‑control systems (DPF, SCR), provided it meets low‑SAPS requirements, which allows the particulate filter to retain its efficiency. In the XENUM catalogue this viscosity is represented by the professional hybrid motor oil XENUM SEMIX 10W30, which combines a synthetic base with di‑ezole additives for enhanced oxidation and wear resistance. Choosing 10W‑30 guarantees proper cylinder protection, stable performance under load, and compliance with manufacturers’ recommendations across a wide temperature range.
