Why choose Diesel Gard 15W-40 CK-4/SN
Advanced protection for diesel engines. Duckhams Diesel Gard 15W-40 CK-4/SN is a top-tier multigrade diesel engine oil for heavy-duty diesel engines. Formulated using modern additive technology and high-quality virgin base oils, it meets current specifications and provides advanced protection for all vehicles operating under severe conditions. It is designed for naturally aspirated and turbocharged, highly rated diesel engines, including those with Exhaust Gas Recirculation (EGR) systems meeting Euro VI emissions standards, operating under severe conditions and extended oil drain intervals. It is backward compatible with older Euro I to V engines and can be used where API CJ-4 and earlier oils are specified. May also be suitable for other vehicles. Please refer to the owner's handbook and the product specification shown.
- Mid SAPS formulation, compatible with Diesel Particulate Filters (DPFs), Selective Catalytic Reduction (SCR/AdBlue) and Diesel Oxidation Catalysts (DOCs) emissions after-treatment devices.
- Excellent deposit control prevents soot-related wear and oil thickening, extending engine life within recommended oil drain intervals.
- Excellent detergent technology for engine cleanliness, notably on pistons, reducing deposits, sludge formation and bore polishing, and extending engine life and performance.
- High TBN neutralises acids formed by combustion, reducing corrosive wear and extending engine life throughout recommended oil drain intervals.
- Strong oxidation and thermal stability, using the latest additive technology, prevents oil thickening and maintains viscosity, ensuring top performance and fuel economy throughout recommended oil drain intervals.
