“…In order to meet these requirements, manufacturers are turning to the more expensive synthetics due to their superior performance [1]. Whether the chosen oil consists of a pure synthetic base stock or the cheaper option of blending both mineral and synthetic base stocks, formulations demonstrate better thermal and oxidation stability, viscosity-temperature behavior, tribological properties, and biodegradability [2][3][4][5]. Synthetic ester base stocks are one such example, which additionally boast the capability of being tailored to a specific application due to the high degree of control in the synthesis process.…”
