Key benefits

  • Lower maintenance costs from minimized piston crown deposits.


  • SAE 10W-40 multi-grade viscosity ensures improved oil circulation and reduced friction at start-up and maximum lubricity at higher operating temperatures.


  • Excellent oxidation stability & BN retention ensure negligible oil degradation and improves oil service life in turn providing longer drain intervals.


  • Lower oil consumption due to high shear stable VI improvers and low volatile synthetic base fluids.
