Gulf Syngear LL 75W-90

Supreme Performance Heavy Duty Automotive Gearbox Oil

Gulf Syngear LL series are fully synthetic supreme performance manual transmission lubricants specially developed for heavy duty transmissions used in on-road commercial vehicles, off-highway equipment and passenger cars operating in most severe conditions. These are blended from synthetic base fluids and advanced technology additive system to provide enhanced gear shift ability, extended service life and excellent protection against component wear & oil seal deterioration. These oils possess outstanding load-carrying capability and high viscosity index to provide reliable lubrication in applications encountering high-speed/shock load and low-speed/high torque conditions and wide temperature ranges. Gulf Syngear LL, SAE 50 is approved as Genuine Roadranger lubricant and SAE 75W-80 and SAE 75W-90 meet the most stringent requirements of Volvo for extended drain intervals.

Features & Benefits

  • Meets the performance requirements of synchromesh transmissions which includes synchromesh compatibility, thermal stability and shift feel
  • Unique additive technology provides outstanding load bearing characteristics resulting in longer gear and bearing life and hence reduced maintenance costs and enhanced equipment durability
  • Exceptional thermo-oxidative stability helps in minimizing high temperature deposit formation 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 and bearing life and improves shifting performance
  • Outstanding low temperature fluidity reduces wear at start-up and helps in smoother shifting at low ambient temperatures
  • Superior frictional properties provide improved fuel economy (SAE 75W-80)
  • Excellent seal compatibility helps minimise leakages and reduce chances of contamination

Applications

  • SAE 50 is exclusively developed for Eaton Gearbox and is approved as Genuine Roadranger Lubricant in syncromesh gearboxes including those with integrated retarders
  • SAE 75W-90 (for ambient temperatures even above 30ºC) and 75W-80 (for ambient temperatures even below -25ºC) are specially developed for Volvo manufactured manual Transmissions
  • Manual Transmission of Heavy Duty On-highway and Off-highway vehicles requiring such quality oils
