Premium Conventional

Product Drum


DRYDENE DIESELALL® HD 30W is a low ash, single viscosity engine oil designed for use in older model diesel engines in both on-highway and off-highway applications as well as hydraulic systems requiring a high-zinc 30W engine oil.



DRYDENE DIESELALL® HD ENGINE 30W is recommended for use in a variety of heavy-duty diesel engine types:

  • Naturally aspirated, turbocharged or supercharged (four-stroke) requiring a single viscosity  fluid.
  • Older model mobile farming, mining and construction equipment.
  • Formulated for older model engines operating on low, medium or high sulfur diesel fuels.



DRYDENE DIESELALL® HD 30W is blended from premium base stocks and specific additives to provide dual-purpose performance in both crankcase and hydraulic systems.

  • Detergent and dispersant additives help maintain engine cleanliness, suppress varnishing and aids in suspension of soot and contaminants in the oil.
  • Robust anti-wear additives help extend regular drain intervals and overall engine life even in high operating temperature applications.
  • Reliable performance in cold weather applications, especially in hydraulic systems.



  • API Services Categories CF-2
