Abstract
We provide a base oil, comprising one or more oligomerized olefins, wherein the base oil has: d. a kinematic viscosity at 100° C. greater than 2.9 mm2/s; d. a viscosity index from 25 to 90; and f. a cloud point less than −55° C. We provide a base oil made by oligomerizing propylene in an ionic liquid catalyst, where the base oil has a viscosity index from 25 to 90 and the base oil is colorless. We also provide a base oil made by oligomerizing an olefin feed comprising propylene in an acidic alkyl-pyridinium chloroaluminate ionic liquid, wherein the base oil has a viscosity index at 100° C. greater than 2.9 mm2/s, a viscosity index from 25 to 90, and a cloud point less than −55° C.
