Powerflow™ NZ Hydraulic Oil

Non-toxic, Zinc-Free Antiwear Hydraulic Oil; Inherently Biodegradable

Phillips 66®Powerflow NZ Hydraulic Oil is a high-quality, zinc-free antiwear hydraulic oil specifically developed for use in industrial and mobile equipment operating in environmentally sensitive areas. It is specially formulated for reduced environmental impact in case of leaks or spills. It is non-toxic to fish and aquatic species as determined by OECD Test Method 203 1-12, and is classified as inherently biodegradable by the OECD Test Method 301B. It passes the visual “no sheen” requirements of the U.S. EPA Static Sheen Test.

Features & Benefits

  • Excellent oxidation resistance and thermal stability
  • Protects against rust and corrosion (reduced sludge and deposit formation)
  • Excellent water-separating properties
  • Excellent wear protection for hydraulic pumps and motors
  • Improved product compatibility with traditional zinc-based products
  • Outstanding air release properties
  • Inherently biodegradable
  • Non-toxic to aquatic organisms

Note: Powerflow NZ Hydraulic Oil is compatible with most zinc-containing hydraulic oils, however, mixing the two products will lessen the environmental and performance benefits normally gained by using Powerflow NZ Hydraulic Oil.


  • Hydraulic systems where the equipment manufacturer specifies a zinc-free antiwear hydraulic oil
  • Hydraulic equipment used in environmentally sensitive areas, such as national parks, wildlife refuges, ski resorts and other recreational areas
  • Hydraulic jacks and other equipment in machine shops
  • Oil drilling rigs and offshore platforms
  • Marine cargo winches and steering systems
  • Hydraulic hoists and service station lifts
  • Chain drives
  • Electric motor bearings
