DRYDENE DIESELALL® 15W40 CK-4 HEAVY DUTY ENGINE OIL is a superior engine oil formulated with the latest additive technology to protect and extend the life of hard-working engines.



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

  • Formulated to handle today’s heavy-duty turbocharged diesel engines as well as naturally aspirated units.
  • Suitable for use in off-road applications such as mining, agriculture and heavy construction even if higher sulfur fuels are being used.
  • Fully backward compatible to CJ-4 and prior API specifications.

Do you operate a mixed fleet?  No problem. DRYDENE DIESELALL® 15W40 CK-4 is well-suited for use where operators want to consider performance and economics with one fluid.



DRYDENE DIESELALL®15W40 CK-4 is specifically designed to meet today’s rigid low emissions and fuel economy standards.

  • The  oil maintains its superior strength by being built with the very best base oils available.  The stronger the foundation, the better the oil.
  • Formulated with a unique blend of modern diesel engine oil additives to help prevent the buildup of harmful engine deposits and extend engine life.
  • Protects against wear, oxidation, sheering and thermal breakdown which can lead to costly repairs and even costlier downtime.
  • Fortified to provide superior sheer stability performance and viscosity retention even under heavy loading.
