Gear Power HDX 90 oil is a high performance axle  with the latest additive technology to meet the requiremnts of Mercedes Benz, MAN and ZF.


  • Automotive transmissions
    Heavily loaded axle drives and non-synchronised transmissions.

Performance Features

  • Longer oil drain capability
    Higher reserves of additives ensure long-term protection of gears. Longer oil life, as a result of higher oxidation stability and lower running temperatures, also leads to extended oil drain intervals.
  • Longer gear life
    Clear improvements in protection against wear prevent premature failure. High oxidation
    resistance also prevents damaging deposit formation in axles.
  • Greater efficiency
    Optimised friction properties have led to significant reductions in power loss and peak temperatures. Ideal shear-stable formulation with improved flow properties at low temperatures enhances efficiency.
  • Less environmental pollution
    Reduced environmental pollution and improved recyclability result from the significantly lower
    chlorine content. Markedly improved seal compatibility increases protection against leaks..
