Duragard® Diamond Plate® SAE 10W-30 API CK-4 Synthetic Blend Engine Oil

Duragard® Diamond Plate® SAE 10W-30 API CK-4 Synthetic Blend Engine Oil is an extreme performance high-temperature, high-shear (HTHS) viscosity formulation engineered for modern heavy-duty diesel engines. Developed to meet the significantly enhanced CK-4 specifications for 2017 and newer engines, it remains fully backward compatible with 2016 and earlier engines previously requiring CJ-4.

This advanced synthetic blend provides superior oxidation resistance for hotter-running engines, helping to minimize acid formation, deposit buildup, and viscosity increase. The balanced additive system promotes reduced engine wear, enhanced shear stability, improved oxidation control, and effective foam prevention, delivering dependable performance in demanding operating conditions.
