It is blended from synthetic base fluids and advanced technology additive system to provide unmatched protection for extended durability of driveline components and enhanced fuel efficiency. Gulf Syngear FE 75W-90, possessing outstanding load-carrying capability and high viscosity index, provides effective lubrication in applications encountering high-speed/shock load and/or low-speed/high torque conditions and wide temperature ranges. It is approved as Genuine Roadranger lubricants and also exceeds the requirements of ArvinMeritor and other major global OEM/ industry specifications.

Features & Benefits

  • Superior lubricating properties provide improved fuel economy compared to mineral oil based SAE 80W-90 and synthetic 75W-90 axle lubricant.
  • Unique additive technology provides outstanding load bearing characteristics resulting in longer gear and bearing life and leading to reduced maintenance costs and increased vehicle uptime.
  • Exceptional thermo-oxidative stability helps in keeping the gear clean for longer periods and extending the oil life significantly longer than conventional gear oils
  • Effective rust and corrosion protection, especially to copper and its alloys reduces wear, extends synchroniser life and improves shifting performance
  • Outstanding low temperature fluidity reduces wear at start up even under low ambient temperatures
  • Exceptional shear stability helps in retaining viscosity and film strength to protect against wear even under severe operating conditions.


  • Exclusively developed for Dana Axles and is approved as Genuine Roadranger Lubricant with Fuel Economy capabilities
