Duragard Diamond Plate SAE 15W-40 API CK-4 Synthetic Blend Engine Oil

Duragard® Diamond Plate® SAE 15W-40 API CK-4 Synthetic Blend Engine Oil is a premium heavy-duty lubricant engineered for extreme high-temperature, high-shear (HTHS) performance. Designed to meet the significantly enhanced requirements of 2017 and newer engines, it remains fully compatible with 2016 and prior engines that previously required API CJ-4 oils.

This advanced synthetic blend formulation delivers superior oxidation control for hotter-running engines, helping to minimize acid formation, sludge, deposits, and viscosity increase. The result is reduced wear, improved shear stability, enhanced oxidation resistance, and dependable foam control under demanding operating conditions.

Performance Benefits

  • High-temperature, high-shear viscosity stability
  • Improved oxidation protection for modern engines
  • Reduced deposit formation and acid buildup
  • Enhanced wear protection for extended engine life
  • Excellent shear stability and foam prevention
