Cummins CES 20078

The Cummins CES 20078 specification defines the requirements for engine oils that provide maximum protection for heavy-duty Cummins diesel engines under high loads and a wide temperature range. Oil that meets CES 20078 must comply with API CJ‑4 and ACEA E7 requirements, have a low content of sulfate, aromatic and phosphorus compounds (low‑SAPS) and support stable operation of after‑treatment systems (DPF) without damaging the catalyst. This standard applies to series Cummins ISB, ISX, QSK engines, as well as similar models installed in trucks, buses and special equipment. When selecting oil on xenum.ua, users rely on XENUM DIESEL POWER or XENUM DIESEL SYNTH products with viscosities 5W‑30, 10W‑40, 15W‑40, 20W‑50, which meet E4‑E11 levels and guarantee long‑lasting performance. Thanks to CES 20078 approval, the oil provides reduced wear, stable DPF operation and increased engine efficiency.
