Product Specifications: 4L, 18L | Executive Standard: GB11122-2006 | Product Description: Viscosity Grades: 10W-30, 15W-40, 20W-50 ● Formulated using imported hydro-refined base oils and premium imported additive packages through a rigorous blending process. Quality meets API CH-4 specifications, as well as requirements from major global automakers such as ACEA E7, Mack EO-M+, MB 228.2/3, MAN M3275, MTU Type 2, and Cummins 20076/77. ● Features superior detergency and dispersancy to effectively inhibit sludge formation, providing optimal lubrication and protection for engines operating under high-temperature, heavy-load conditions for extended periods. ● High-quality base oils ensure excellent low-temperature startability, effectively reducing instantaneous friction and wear during cold starts and providing comprehensive engine protection. ● Carefully selected imported additives provide outstanding oxidation and corrosion resistance, effectively inhibiting the formation of acidic substances, extending oil service life, and reducing engine operating costs. ● Pressure-stabilizing, low-energy-consumption diesel engine oil featuring "Poly-Molybdenum Ion" technology and advanced rolling friction reduction. Suitable for: CH-4+ ● Suitable for turbocharged, heavy-duty, electronically controlled diesel engines requiring CH-4 grade oil; ideal for heavy-duty trucks operating on highways. Meets European emission standards. Suitable for large, heavy-duty container transport vehicles, as well as construction machinery and mining equipment operating under harsh conditions.
