Provided are lubricants containing a synthetic ester, one or more additional base stocks and an additive package along with methods of making and using the same. Lubricant compositions comprise a synthetic ester that is a reaction product of at least one hindered organic polyol with one or more carboxylic acid where at least some (20%) up to 100% of the acids are branched. The lubricant compositions can provide improved oxidation stability and extended service life, as compared to a lubricant whose ester component is the reaction product of one or more hindered organic polyols and one or more carboxylic acids that are all linear, in applications that involve exposure to air, moisture, and/or high temperatures. These lubricant compositions are suited to a variety of lubricant applications, including, but not limited to air compressors, gear boxes, bearing sets, hydraulic systems, and chain drives.
