ABSTRACT:
A thermal oxidatively stable synthetic fluid composition is disclosed. The composition is essentially comprised of an aromatic carboxylic acid ester of the general formula ##STR1## 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, R.sub.1 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 R.sub.1 is monovalent, when a is 2 R.sub.1 is divalent, when a is 3 R.sub.1 is trivalent and when a is 4 R.sub.1 is tetravalent, R.sub.2 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.
