Polyorganosiloxane traction fluids which contain significant amounts of mono-organosiloxane units are described. Specifically, the disclosed polyorganosiloxane traction fluids contain 7 to 45 weight percent siloxane units of formula [RSiO3/2], 40 to 90 weight percent of siloxane units of formula [R2SiO], and 0 to 20 weight percent of siloxane units of formula [(CH3)3SiO1/2] where the molar ratio of [R3SiO1/2] units to [RSiO3/2] units is less than 1 and where R is either cyclohexyl radicals, phenyl radicals, and/or methyl radicals. The polyorganosiloxane traction fluids of this invention are particularly well suited for use in traction drive systems and transmissions subject to wide operating temperature conditions.
