A traction fluid comprising a blend of 2,3-dicyclohexyl-2,3-dimethylbutane (HAD) and 2,3-dicyclohexyl-2,3-dimethylbutane (iso-HAD) is found to have a lower viscosity at low temperatures when compared to a traction fluid having only HAD or only iso-HAD as a base fluid with no compromise to traction coefficient. The traction fluid may comprise additives. The traction fluid usually comprises HAD:isoHAD between about 8:1 to about 1:3. Further, the HAD:iso-HAD traction fluid blend is produced by a method of simultaneous co-production of hydrogenated HAD and hydrogenated iso-HAD from an alpha styrene dimer and an iso-HAD precursor with a yield of about 90% in a method that does not require a purification step.
A traction fluid comprising a blend of the molecule of Formula I:
