  • Caterpillar TO-4
  • Allison C-4
  • Dana Transmissions
  • Eaton Transmissions
Performance Benefits
  • Controlled friction performance with seven friction materials, both metallic and non-metallic.
  • Stable friction characteristics, eliminating the problems of excessive brake noise, weakening of the binder in paper materials, and embrittlement of elastomeric materials.
  • Eliminates clutch slippage, even under heavy loads on steep inclines. No need to constantly adjust equipment to maintain proper clutch setting.
  • Excellent oxidative stability
  • Exceeds wear requirements of Caterpillar TO-4
  • Excellent low-temperature fluidity, providing easier cold-weather starting and better wear protection under these conditions.
  • Excellent shear stability to maintain viscosity grade over the life of the equipment, providing long-term antiwear protection.
  • Protection against copper corrosion and rust.
  • Maximum foam protection, ensuring no trapped air that could lead to metal-to-metal contact and wear
Product Highlights

They exhibit excellent friction performance, wear protection and material compatibilty compared to mixed fleet engine oils which were previously used for these applications. They also meet Caterpillar's TO-4 specification which cannot be met with engine oils.
