PSO DEO Max CK-4/SN SAE 15W-40 is a synthetic Heavy-Duty Diesel Engine Oil, developed to meet the lubrication requirements of modern diesel fueled vehicles. A balanced combination of fully synthetic base oil and unique state-of-the-art additive technology makes DEO CK-4 next generation lubricant. Oil is compatible with modern low emission diesel engines equipped with Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF) & Exhaust Gas Recirculation (EGR) systems.

Product Data Sheet Material Safety Data Sheet

    • Longer Oil Drain Interval: Up to 60% improved performance against oxidation*, viscosity loss and oil aeration under the most severe operating conditions to improve oil drain intervals.
    • Improved Engine Life: Excellent detergency ensures to control deposits on engine parts even at high temperature to keep engine clean for enhanced engine life.
    • Reduced Emission: Low-SAPS additive technology having low sulfated ash, phosphorus and sulfur enhances the life of exhaust emission system to ensure reduced emission in environment.
    • Minimizes Inventory Management Cost: Can be used in diesel engines where API CK-4/SN, CJ-4, CI-4 Plus, CI-4 & CH4/SN are recommended.
    • Reduced Fleet Management Cost: Outstanding soot dispersion in oil keeps fuel’s soot suspended thus preventing filter plugging, cylinder head sludge, abrasive polishing wear and oil thickening. Improves equipment durability and reliability.
