  • Reduces internal friction within the engine, increasing engine efficiency, and reducing fuel consumption extending engine life and reducing running costs.
  • Provides exceptional anti-wear and corrosion protection extending component and engine life.
  • Stay in grade formulation designed to maintain the viscosity of the oil, ensuring suitable protection for engines throughout extended oil drain intervals, irrespective of driving style.
  • Excellent low-temperature properties ensure rapid lubrication throughout the engine giving improved cold starting and minimising engine wear at start-up.
  • Thermally stable formulation reduces sludge and deposit formation keeping the engine clean to ensure the engine runs at its full potential from oil change to oil change.
  • Low volatility synthetic base oil reduces oil consumption and oil thickening and gives lower hydrocarbon emissions
