Power and Protect Heavy Duty Equipment with TO-4 Fluid


We're pleased to report that after several years in the market, Phillips 66 Lubricants' next generation TO-4 fluid, branded as Phillips 66 Torque Fluid, Conoco PowerDrive®, 76 HT/4 Fluid and Kendall Powershift Transmission Fluid, is still the only purpose-built TO-4 fluid to receive Allison TES-439 global approval. With today's machinery running hotter, faster and longer while under heavier loads and in tougher conditions, our TO-4 fluid has become stronger. Built for industry demands and formulated with a remarkable additive system, this outstanding fluid lets you haul bigger loads with less gear and pump wear to help customers get more done.

The key product benefits are detailed below.

  • Superior wear and load protection and industry-leading friction performance: After analyzing test run results, researchers found that our TO-4 fluid outperformed competing products with regard to maintaining friction during continued brake and transmission performance throughout rigorous work cycles.
  • Corrosion protection and oxidation stability: Our fluid provided superior oxidative stability and protection against corrosion in comparison to competitive fluids.
  • Better pumpability and flow: The pour point and flow of our TO-4 fluids were found to be superior to competitiors' HDEO-derivative 10W products, providing a huge advantage in the many states where winter temperatures can make that a critical property.
