ABSTRACT:
The disclosure relates to a composition suitable for use in mechanical power transmission devices. It has as its principal component a hydrocarbon oil which has from 19 to 30 carbon atoms, inclusive, and three six-membered carbocyclic rings and consists of a mixture of compounds having the following formula: ##STR1## wherein R.sup.1 is a divalent straight or branched chain radical C.sub.y H.sub.2y where y is an integer of 1 through 3; R.sup.2 is a straight chain radical C.sub.z H.sub.2z where z is an integer of 1 through 3; R.sup.3, R.sup.4, and R.sup.5 are the same or different alkyl groups having from 1 through 4 carbon atoms; l, m, and n each is an integer from zero through 3; and x is zero or 1; and wherein rings A and B are hydrogenated benzene rings and ring C is a hydrogenated benzene ring when x is 1 and a hydrogenated benzene ring or a cyclohexane ring when x is zero said hydrogenated benzene rings being saturated with hydrogen to the extent of at least 80% but less than 100% of the theoretical, and the composition can additionally contain one or more of an antioxidant, a rustproofing agent, a viscosity index improver, and antifoaming agent.
