  • Clean-gear performance under conditions of high temperature and oxidation
  • Excellent phosphorus retention, ensuring extended wear protection
  • Low chlorine content in blended industrial gear oils
  • Consistently strong micropitting performance as specified by Flender AG at 60°C and 90°C
  • Rationalisable from HiTEC 317 additive plus HiTEC 301 additive Top Treat (ashless)
  • Performance exceeding the requirements of U.S. Steel 224, AGMA 9005-E02 and DIN 51517, Part 3
  • Approved by SKF and FAG in PAO/ester for use in wind turbine applications
