Premium Quality Transmission and Drive Train Oils

Detail Description

HP POWERFLO TO-4 grades are premium quality Transmission and Drive Train Oils formulated from high quality hydro-treated base stocks and carefully selected additives, designed to meet the Caterpillar TO-4 lubricant specifications.

HP POWERFLO TO-4 grades maximize the life of the frictional materials in power-shift transmissions, eliminate the chatter in wet brake mechanisms and protect drive train gears against wear, used in off-road equipment.


HP POWERFLO TO-4 grades are recommended for use in Caterpillar equipment having

  • Power-shift and Hydrostatic Transmissions
  • Wet Brake Mechanisms
  • Differentials and Final Drives
  • Hydraulics

The product can also be used in most of the other off-road equipment requiring an Allison C-4 fluid of the similar viscosity grade.

Features and Benefits

  • Balanced lubricity and other functional properties
  • Unmatched performance in operation of power-shift clutches and wet-brake mechanisms
  • Minimizes clutch-plate wear and brake chatter
  • Minimizes wear in high pressure hydraulic pump systems
  • Superior oxidation and deposit control to render new-like performance
  • for longer service intervals
  • Superior protection against Rust and Corrosion

Our Clients

This is the easiest way to estimate a manufacturer's market reputation and credibility. Check out the list of clients that the manufacturer has worked with or continues to work. The more and larger companies that they have as clients, the better you can trust them. After all, weren't they good enough, big brands would not have worked with them in the first place.
