Product Description
Samic Optima Platinum 15W-40 CJ-4/SN is an extra high-performance diesel engine oil formulated with
severely refined base stocks and advanced technology additives to provide reliable engine performance in
the latest emission designs, including those with Exhaust Gas Recirculation (EGR) systems and after
treatment systems with Diesel Particulate Filters (DPF) and Diesel Oxidation Catalysts (DOC), as well as
satisfying the needs of older engines. It may be used in naturally aspirated and turbocharged diesel &
petrol engines and On & Off-highway applications, providing excellent protection even under the most
strenuous conditions.
Performance & Customer Benefits
• Outstanding oxidation & thermal stability reduces sludge deposits and keeps the engine cleaner.
• Excellent engine protection by providing outstanding protection against corrosive & abrasive wear.
• Improved shear stability maintains viscosity in grade under severe, high-temperature service conditions.
• Excellent low-temperature pumpability ensures improved fuel economy.
• Excellent dispersancy provides outstanding soot control in Exhaust Gas Recirculation (EGR) systems.
• Excellent TBN reserves provide improved acid neutralization and corrosion protection, which helps in
extending oil drain interval in both new & old engines using either low (500 ppm) or ultra-low (15 ppm)
sulfur diesel fuel.
