Duragard® Diamond Synthetic® CK-4 SAE 5W-40 Engine Oil is is an extreme performance (HTHS) high-temperature, high-shear viscosity fully synthetic oil formulated to meet high-performance demands with long drain capabilities, possible increase in fuel efficiency and reduced over all costs. CK-4 will deliver more oxidization protection for hotter, heavy-duty engines, minimizing acid formation, deposits and viscosity increase, promoting reduced wear, improved shear stability, greater oxidation stability, and foam prevention. Suitable for mixed fleets.

Duragard® Diamond Synthetic® CK-4 SAE 5W-40 Engine Oil is a new formula that is specifically engineered for use in mixed fleets, gasoline and diesel. CK-4 has a select additive package for exceptional performance at high temperatures and heavy loads with improved engine protection over previous CJ-4 formulas. The advance in oil technology standards establishes an oil quality specification that helps protect today and tomorrow diesel engines.

Duragard® Diamond Synthetic® CK-4 SAE 5W-40 Engine Oil is a direct replacement for CJ-4 using the same viscosity grades in Synthetic or Synthetic Blend oil types providing protection for all future engine designs, while improving protection of current and previous engines. CK-4 and CJ-4 can be mixed and should have no detrimental impact to engines. However, it is recommended to completely change over to CK-4 oil by using a hot drain of the CJ-4 oil to help minimize residual oil and achieve full benefits of the new oil. Fleets using CJ-4 should implement a secondary storage for CK-4 or completely empty a CJ-4 tank before filling with Duragard® Diamond Synthetic® CK-4 SAE 5W-40 Engine Oil.

Benefits:

  • * Exceeds warranty requirements of engine manufacturers that require a type API CK-4/SM premium 100% synthetic SAE 5W-40 motor oil.
  • * Exceeds performance of current API CJ-4 oils.
  • * (HTHS) High-temperature, High-shear viscosity.
  • * Improved shear stability
  • * More oxidization protection for hotter, heavy-duty engines.
  • * Minimizes acid formation
  • * Reduced deposits
  • * Extended drain intervals
  • * Backwards compatible for all engines currently requiring CJ-4
  • * Meets current 2017 and newer specifications requiring CK-4
  • * Meets Ford’s stringent 2017 and newer WSS-M2C171-F1 & prior specification.
