Sinopec 10W Heavy Duty Transmission fluid is suitable for use in:

  • Heavy-duty transmissions, gearboxes, final drives and hydraulic systems used in off-highway applications, where a Caterpillar TO-4 product is recommended.
  • Other heavy-duty applications in the mining, construction, quarrying and agricultural industries.
  • Manual, power-shift and automatic transmissions where Allison C-4 fluids (SAE 10 W and 30 grades) are recommended.
  • When Komatsu power train oil TO10 is needed.
  • Mobile hydraulic equipment applications.
  • Applications where paper and elastomer disc materials are used, and advanced frictional properties are required to extend clutch life and provide slippage control under severe high-load conditions.

Features and benefits

  • Excellent antiwear properties and load carrying ability reduce gear wear and extend the life of heavy-duty transmission systems, gearboxes and final drives, leading to increased productivity and reduced equipment downtime.
  • Outstanding oxidation stability, thermal stability and detergency prevent the build up of deposits and ensure long fluid life.
  • Advanced frictional properties provide the clutch-friction retention and slippage control required in equipment that uses modern paper or elastomer disc materials.
  • Compatible with modern clutch materials and elastomers, to extend component life and prevent oil leakage.
  • Effective control of foaming together with good air-release properties ensure smooth transfer of power and shifting performance, and reduce fluid loss in severe service conditions.
  • Very good low-temperature properties protect against wear under cold start up and running conditions.
