Customer Benefits

  • Minimizes operating costs Rapid circulation and reduced drag on gears reduces gear wear, and provides fuel economy benefits.
  • Reduces maintenance Excellent thermal and oxidative stability reduces deposit formation under severe operating conditions. This keeps gears and bearings cleaner, preventing oil film disruption which can result in increased wear rates. Effective anti-rust additives protect transmission components. High oxidation stability provides extended drain intervals.
  • Minimizes inventory costs Naturally high viscosity index ensures effective lubrication over a wide range of temperatures. This allows use in a variety of applications, and eliminates any need for separate summer and winter grade gear oils.


It is designed to provide excellent protection for non-synchronized heavyduty manual transmissions and automated manual transmissions (AMTs) which do not require EP type gear oils. The superior properties of the synthetic base fluid are further enhanced with anti-wear agents and rust and oxidation inhibitors.


  • North American type, heavy duty non-synchronized manual transmissions and automated manual transmissions such as those manufactured by Eaton and Mack.
  • ZF Freedomline automated manual transmissions
  • Specially suitable where operating conditions are severe or where equipment must operate in extremely hot or cold climates

Always confirm that the product selected is consistent with the original equipment manufacturer’s recommendation for the equipment operating conditions and customer’s maintenance practices.
