Cummins CES 20077

Cummins CES 20077 approval is a motor oil specification developed specifically for heavy‑duty Cummins diesel engines installed in trucks, buses and special equipment. Oil that meets CES 20077 must satisfy API CJ‑4/CK‑4, ACEA E7 and have a low SAPS content, ensuring compatibility with after‑treatment systems (DPF) and catalysts, as well as guaranteeing wear protection under high loads and a wide temperature range. The specification is targeted at ISB, ISX, QSK engine families, as well as variants that use intercooler‑equipped turbos and elevated oil pressure. Requirements include high oxidation resistance, viscosity retention at high temperatures and effective lubrication of hydraulic system bearings. When selecting oil on xenum.ua, the XENUM DIESEL POWER or XENUM DIESEL SYNTH products in viscosities 5W‑30‑20W‑50, which have an E7‑E11 level, fully comply with CES 20077 and provide long‑lasting engine operation.
