DRYDENE DIESELALL PLUS® 15W40 CK-4 HEAVY DUTY ENGINE OIL is synthetic blend diesel engine oil blended from synthetic base stocks and utilizes premium additive technology to meet the latest OEM diesel engine high temperature/high sheer performance requirements.



DRYDENE DIESELALL PLUS® 15W40 CK-4 is recommended for use on current specification on-road equipment employing low emissions technology including EGR (Exhaust Gas Recirculation), SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filtration).

  • It is designed for use when extended drain intervals are desired as well as where extreme operating conditions may exist.
  • Formulated to handle today’s heavy-duty turbocharged diesel engines as well as naturally aspirated models.
  • Fully backward compatible to CJ-4, CI-4 Plus, CI-4 and prior API specifications.

DRYDENE DIESELALL PLUS® 15W40 CK-4 is well suited for use in construction, mining and agricultural applications where ultra low sulfur diesel fuels are being run.



DRYDENE DIESELALL PLUS® 15W40 CK-4 is the next generation of CK-4 diesel engine oil.  With its unique additive formulation and high viscosity index, it delivers unsurpassed protection in many key areas:

  • Helps extend oil drain intervals (ODI) in conjunction with OEM recommendations.
  • Improved engine cleanliness and protection against deposit formation in pistons.
  • Advanced protection against oxidation, acid formation and viscosity breakdown due to high-temperature applications.
  • Extends the life of critical wear surfaces, gaskets and seal materials.
  • Low-ash fomulation helps control fouling of exhaust after-treatment devices, extending useful life while lowering long-term operating
