Patent ID: 8053614

Claim:
A base oil comprising branched saturated hydrocarbons having carbon numbers from C18 to C36, the base oil comprising at least 90% by weight of saturated hydrocarbons, less than 10% by weight of linear paraffins, not more than 0.1% by FIMS of fused polynaphthenes, 5-50% by FIMS of mononaphthenes, and at least 50% by weight of the saturated hydrocarbons have a width of the carbon number range of no more than 7 carbons, wherein the base oil has a kinematic viscosity at 100° C. of 3 to 8 cSt, a CCS-30 viscosity of no more than 34.066*(KV100) 2.3967 and a CCS-35 viscosity of no more than 50.501*(KV100) 2.4918 cP, and which base oil is derived from starting material of plant biological origin.
