Delo 400 XLE SAE 15W-40 (Synblend) with ISOSYN Advanced Technology is an API CK-4 heavy duty engine oil specifically formulated for on highway applications, including 2017 greenhouse gas (GHG 17) compliant diesel engines with lower CO2 emissions, in addition to 2010 compliant low emission diesel engines with Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems calling for SAE 15W-40 premium heavy duty motor oil. Delo 400 XLE SAE 15W-40 with ISOSYN Advanced Technology is also recommended for off highway Tier IV emission compliant engine applications where an SAE 15W-40 viscosity grade is required. It is formulated for newer engines with Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems. Additionally, Delo 400 XLE SAE 15W-40 is recommended for use with transmissions that require the Allison TES-439 specification in heavy duty off-road applications. It is fully compatible with previous engine models and previous API Oil Service Categories. Delo 400 XLE SAE 15W-40 delivers value through: Exceptional Deposit Control - Provides high performance piston deposit control and turbocharger protection due to its superb oxidation performance. Its high performing detergent and dispersant additives provide excellent diesel engine component protection. Better Low Temperature Pumpability - Improved flow rate and pump ability versus conventional SAE 15W-40 oils and similar pour point to conventional SAE 10W-30 products with better cold flow properties than conventional SAE 15W-40 products. Superb Long Drain Performance -Formulated for exceptional long oil drain protection for both on and off-road diesel engines. Minimized Operating Costs - Exceptional soot dispersancy and wear control. Cylinders, pistons, rings, and valve train components are well protected against wear and corrosion, providing optimum service life and minimal maintenance. Contributes to maximum equipment utilization and minimal downtime. Excellent Emission Control System Life -Provides optimum Diesel Particulate Filter (DPF) life for minimal downtime and cleaning, thus managing your maintenance costs.
