Industrial Oil

Highly Refined Paraffinic Mineral Oil

Phillips 66®Industrial Oil is a highly refined, non-compounded (no additives) paraffinic mineral oil recommended for use as a high-quality process oil, diluent oil, flush oil, or blending component for other lubricants. It also is recommended for general-purpose lubrication in applications that do not require a compounded oil.

Features & Benefits

  • Uniform quality and chemical composition
  • High natural oxidation stability
  • Good viscosity-temperature characteristics
  • Low volatility
  • High flash point
  • Good solvency
  • Very light color (except 2500 grade)
  • Non-staining
  • Quick foam release


  • Process oil
  • Compounding oil for rubber products and adhesives
  • Blending component for other lubricants
  • Flush oil for gas and steam turbines
  • Mineral seal oil
  • Chain drives and other “once-through” applications
  • General-purpose lubrication in applications that do not require a compounded oil
