Overview

YIDUN API CH-4 diesel engine oil is developed and manufactured by Baoding Muhai Lubricating Oil Import & Export Co., Ltd. Formulated with premium fully synthetic base stocks and high-performance heavy-duty additive packages. It delivers higher performance than CF-4 grade, specially designed for high-load 4-stroke diesel engines. It reliably handles severe operating conditions such as long-distance transportation, mining and construction sites with high temperature and heavy dust. With excellent soot dispersancy, it reduces piston carbon deposits and cylinder liner wear, suitable for Euro Ⅱ & Euro Ⅲ diesel engines. The 18L large pail is ideal for bulk maintenance procurement of transport fleets, mining and engineering enterprises to cut operating costs.

Key Features

✅ Powerful Wear Protection for Continuous Heavy Load High-performance anti-wear formula forms tough lubricating film on crankshafts, pistons and cylinder liners. It protects engines steadily during long-haul heavy load and climbing operations, reduces component wear and extends engine service life.

✅ Excellent Soot and Sludge Control Superior soot dispersancy prevents soot agglomeration and restrains sludge and varnish formation, keeps engine internals clean and maintains stable power output.

✅ High-Temperature Oxidation Resistance & Extended Oil Life Great thermal stability and antioxidation performance. Resists thickening and aging under high temperature, extends oil drain interval and reduces downtime maintenance.

✅ High Base Reserve, Anti-Corrosion & Broad Fuel Compatibility Sufficient base reserve neutralizes acidic by-products from diesel combustion, protects cylinder liners and bearings, compatible with diesel fuels with different sulfur contents.

✅ Multiple Viscosity Grades for Diverse Climates Available:5W-40,10W-30,15W-40,20W-50, suitable for cold, temperate and tropical regions.

✅ 18L Large Capacity Pail for Enterprise Bulk Maintenance Large-volume barrel reduces frequent repackaging and lowers per-liter oil cost. Preferred choice for fleets, mines and construction machinery for centralized maintenance.
