A traction fluid useful in automotive power transmitting equipment includes a base fluid of polymers of at least one olefin which contains 3 to 5 carbon atoms, hydrocarbon molecules containing non-aromatic cyclic moieties, or mixtures thereof; a low-temperature viscosity control agent selected from the group consisting of oligomers or polymers of linear alpha olefins of at least 8 carbon atoms, naphthenic oils, synthetic ester oils, polyether oils, and mixtures thereof, in an amount sufficient to reduce the low temperature viscosity of the traction fluid; and an additive package including dispersants, detergents, or mixtures thereof, along with other optional additive components.
