Overview
YIDUN API CF-4 diesel engine oil is developed and manufactured by Baoding Muhai Lubricating Oil Import & Export Co., Ltd. Formulated with premium synthetic base stocks and heavy-duty additive packages. Designed for 4-stroke heavy-duty diesel engines. It reliably works under long-term heavy load, high temperature and dusty harsh conditions. The robust oil film reduces component wear and piston carbon deposits. The 18L large pail is ideal for bulk oil change for fleets, mining and large construction machinery.
Key Features
✅ Heavy-Duty Strong Oil Film & Wear Protection Heavy-duty anti-wear formula creates tough lubricating film on crankshafts, pistons and cylinder liners to prevent metal-to-metal contact. Provides stable engine protection during climbing and continuous heavy load, extending engine service life.
✅ Superior Detergency & Soot Control High-efficiency detergent additives keep pistons clean, restrain high-temperature carbon, soot and sludge accumulation, maintain clean engine internals and stable power output.
✅ High-Temperature Oxidation Resistance, Slow Oil Degradation Excellent thermal stability and antioxidation performance. Slows thickening and aging under long-distance high-temperature heavy loads to extend oil drain intervals and cut maintenance costs.
✅ High Base Reserve, Anti-Corrosion & Wide Fuel Compatibility Neutralizes acid by-products from diesel combustion, protects cylinder liners and bearings, compatible with diesel fuels with different sulfur contents.
✅ Multiple Viscosity Grades for Varied Climate Available:5W-40,10W-30,15W-40,20W-50, suitable for cold, temperate and tropical regions.
✅ 18L Large Capacity Pail for Fleet Bulk Maintenance Large-volume barrel reduces frequent repackaging and cuts per-liter cost. Perfect for bulk procurement of fleets, mines and construction machinery enterprises.
