Why choose Diesel Gard Pro 5W-30 CK-4

Duckhams Diesel Gard Pro is a range of top-tier, fully synthetic, long-life multi-grade engine oils for heavy-duty diesel engines. Formulated using cutting-edge additive technology and high-quality synthetic base oils to meet current specifications and provide outstanding long-life protection for all vehicles operating under severe conditions. Duckhams Diesel Gard Pro 5W-30 CK-4 is a fully synthetic, shear stable, high-performance engine oil designed for use in highly rated diesel engines, including turbocharged engines and engines using exhaust gas recirculation, operating under severe conditions, such as significantly extended oil drain intervals. Provides excellent protection against wear and corrosion and maintains engine cleanliness. Meets modern emission standards, reducing environmental impact. Suitable for use in engines fitted with Selective Catalytic Reduction (SCR/AdBlue) NOx reduction systems, Exhaust Gas Recirculation (EGR) systems and Diesel Oxidation Catalysts (DOC), and for use in vehicles fitted with Diesel Particulate Filters (DPFs).

  • Mid SAPS formulation designed to be compatible with exhaust after-treatment devices such as Diesel Particulate Filters (DPFs), Selective Catalytic Reduction (SCR/AdBlue) and Diesel Oxidation Catalysts (DOCs) to extend after-treatment system life, reduce downtime and maintain continued compliance with the latest emissions standards.
  • Effective dispersant additives minimise soot-related wear and prevent oil thickening, maintaining oil viscosity and ensuring the oil continues to lubricate throughout the manufacturer's recommended oil drain interval, extending engine life.
  • Detergent additives minimise deposit formation, notably on pistons, reducing bore polishing and maintaining engine cleanliness. Engine cleanliness ensures continued engine performance and extends component, and engine, life.
  • Good base reserve neutralises acids formed by combustion, reducing corrosive wear throughout the manufacturer's recommended oil drain interval, extending engine life.
  • Premium quality synthetic base oils give excellent oxidative and thermal stability, preventing oil thickening, ensuring the oil stays within grade and maintaining lubrication performance throughout the manufacturer's recommended oil drain interval.
