Drydene Multi-Viscosity Hydraulic Fluid

Premium Conventional

Product Drum


DRYDENE MULTI-VISCOSITY AW 46 is a premium anti-wear hydraulic fluid designed to perform over a wide range of temperatures in hydraulic systems for both mobile and stationary equipment.  It is well- suited for use in both low and high temperature environments.



DRYDENE MULTI-VISCOSITY AW 46 is recommended for use in piston, vane or gear-type hydraulic pumps in industrial, mobile and other types of heavy-duty equipment.

  • May be used to replace single viscosity hydraulic fluids where improved performance is preferred.
  • High viscosity index and low pour point are ideal for both extremely low and high temperature settings.
  • Suitable for use as a general-purpose fluid where standard R&O or straight mineral oils are recommended.



DRYDENE MULTI-VISCOSITY AW 46 delivers extended performance and protection to critical components using modern base oil and additive chemistry to achieve smooth and efficient operation:

  • Multi-viscosity formulation reduces seasonal fluid changes based on temperature conditions.
  • High viscosity index helps maintain consistent viscosity over a broad range of operating temperatures.
  • Enhanced additive package bolsters oxidation resistance and metal-to-metal wear minimization.
  • Foam reducers allow for complete lubrication and smooth performance throughout the operating system.
  • Low pour point exceeds those of most standard, single viscosity hydraulic fluids, making DRYDENE MULTI-VISCOSITY AW 46 an ideal choice for low temperature applications.
