Abstract: A lubricating fluid comprising a base oil, which utilizes carboxylic esters of carboxyl di-end-capped-polyethylene glycols, or a mixture thereof with carboxylic esters of carboxyl di-end-capped-polytetramethylene glycols, to improve low temperature performance, as well as minimize elastohydrodynamic shear strength, and enables the production of high efficiency fluids with enhanced low temperature properties for machines or machine elements that operate in the elastohydrodynamic regime in lubrication.
