Suitable for Euro Ⅱ & Euro Ⅲ diesel engines. The 4L portable pail fits fleet maintenance, construction machinery and agricultural machinery export orders.

Key Features

✅ Powerful Wear Protection for Continuous Heavy Load High-performance anti-wear formula builds stable lubricating film on crankshafts, pistons and cylinder liners. Reliable engine protection during long-distance heavy load and climbing operations, minimizing wear and extending engine service life.

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

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

✅ High Base Reserve & Anti-Corrosion Performance Sufficient base reserve neutralizes acidic by-products from diesel combustion, protects bearings and cylinder liners, compatible with diesel fuels of 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.

✅ 4L Pail with Ergonomic Handle, Easy Filling & Handling Non-slip ergonomic handle for simple pouring and transportation. Ideal for auto parts shops, agricultural stations, overseas retail and small-batch procurement.
