Patent ID: 8535514

Claim:
A lubricating oil, comprising a) at least two base stocks; b) a metallocene catalyzed PAO first base stock comprising at least 5 percent and no more than 90 percent of the lubricating oil having a viscosity greater than 40 cSt, Kv100° C. and the first base stock having a molecular weight distribution (MWD) as a function of viscosity less than algorithm MWD=0.41667+0.725*log(Kv at 100° C. in cSt); c) a second base stock comprising at least 10 percent and no more than 90 percent of the lubricating oil with a viscosity less than 10 cSt, Kv100° C., wherein the metallocene catalyzed PAO first base stock is made from an alpha-olefin selected from the group consisting of a single alpha-olefin of C3 to C30 and at least two alpha-olefins of C3 to C30 with the proviso that the metallocene catalyzed PAO first base stock does not include an ethylene monomer.
