Abstract (en)
A lubricating composition comprising (i) a Fischer-Tropsoh derived base oil, and (ii) lubricant additive at a total level of at most 2% by weight, wherein the lubricating composition has a viscosity index of at least 140 and a kinematic viscosity at 40°c of at most 100 mm 2 /s, and wherein the lubricating composition is essentially free of polymeric viscosity index improver. The lubricating composition of the invention exhibits improved extreme pressure and shear stability properties.
