Abstract: A method is disclosed for improving the cooling of equipment lubricated by functional fluids, such as power train fluids, by lubricating the equipment with a functional fluid comprising a wax isomerate or hydrodewaxate base stock and at least one performance additive thus permitting a reduction in the volume of lubricant used and a concomitant reduction in the size of the lubricant reservoir and related equipment.
