A thermal oxidatively stable synthetic fluid composition is disclosed. The composition is essentially comprised of an aromatic carboxylic acid ester of the general formula (See Fig. I) wherein Ar is an aromatic moiety, R is a neo hydrocarbyl group containing from about 5 to about 18 carbon atoms, with the proviso that R is not a cycloalkyl substituted neo hydrocarbyl group, R1 is a mono, di, tri or tetra functional hydrocarbyl group containing from 1 to about 18 carbon atoms, n is an integer from about 2 to about 4 and represents the total number of carboxylic acid ester groups on the aromatic moiety, a is an integer from about 1 to about 4, when a is 1 R1 is monovalent, when a is 2 R1 is divalent, when a is 3 R1 is trivalent and when a is 4 R1 is tetravalent, R2 is a hydrocarbyl group derived from a diol containing from about 2 to about 18 carbon atoms and x is an integer from 0 to about 4.
