K6 CK‑4 Fully Synthetic Diesel Engine Oil is high‑performance Automotive Lubricants, categorized under QINGJIE, Diesel Engine Lubricants, and also fits Construction Machinery Lubricants. Besides this diesel oil, we also supply Gasoline Engine Lubricants, Commercial Vehicle Lubricants, Industrial Hydraulic Oil & Gear Oil, Automatic Transmission Fluid and full‑set Auto Care Products for one‑stop sourcing for overseas buyers.
It meets API CK‑4 and ACEA E7/E11‑2022 specifications, suitable for National V / VI emission‑compliant diesel engines. Compared with CJ‑4 grade oil, it achieves extended drain intervals and better energy‑saving performance. Formulated with PAO, alkyl naphthalene and ester fully‑synthetic base stocks together with imported composite additives, its low‑SAPS formula effectively protects exhaust after‑treatment components including DPF and SCR. With polyol‑ester and organic‑molybdenum compound technology, it delivers excellent anti‑wear and friction‑reduction performance, strong detergency‑dispersancy, low evaporation loss and high oil‑film strength, offering stable engine protection and extending equipment service life as well as oil drain intervals.
Great acid‑neutralizing capacity and TBN retention enable ultra‑long oil drain intervals when cooperating with OEM long‑life filters. It is widely applied for heavy‑duty diesel engines equipped with EGR, SCR and DPF systems, covering Mercedes‑Benz, MAN, Volvo, Cummins, Yuchai, Weichai and other brands. It also works well on construction machinery, mining equipment and generator sets under severe operating conditions.
4L and 18L packages are available. Bulk orders and customized packaging are supported. As original lubricant manufacturer, every batch undergoes complete performance tests for consistent quality. We provide stable supply and professional technical support for global purchasers.
