Abstract
A composition useful as a base stock for a lubricant in a traction drive transmission has a kinematic viscosity at 210.degree.F in the range of 1.5-200.0 cs. and contains A. from 1-25 parts by weight of a hydrogenated polymer of C.sub.3 -C.sub.8 aliphatic monoolefin, said polymer having an average molecular weight in the range of 180-2000, and B. one part by weight of at least one member selected from PA1 I. at least one saturated adamantane compound, said adamantane compound containing no elements other than carbon, hydrogen, fluorine and oxygen, wherein said oxygen is combined in an ether or an ester linkage or is in a carboxylic acid, hydroxyl or carbonyl group; PA1 Ii. a paraffinic petroleum oil containing less than 1% by weight of aromatics and having an ultraviolet absorptivity at 260 millimicrons of less than 0.5; and PA1 Iii. a mixture of members from (i) and (ii).
