LUBRICATING COMPOSITIONS

摘要

Lubricating composition comprising: (i) one or more additives; (ii) at least 25 % by weight of a first Fischer-Tropsch derived base oil having a kinematic viscosity at 100°C in the range of from 6 mm2/s to 10 mm2/s; and (iii) at least 10% by weight of a thickener selected from a second Fischer-Tropsch derived base oil having a kinematic viscosity at 100°C in the range of from 15 mm2/s to 30 mm2/s, brightstock, deasphalted cylinder oil (DACO), polyisobutylenes and mixtures thereof; wherein the lubricating composition has a TBN of at least 20 mg KOH/g and a kinematic viscosity at 100°C of at least 9 mm2/s. The lubricating composition of the present invention provides excellent lubricant-fuel compatibility.
