A synthetic ester composition which exhibits thermal and oxidative stability, lower friction coefficient and lower wear, wherein the ester composition comprises the reaction product of: a linear or branched alcohol having the general formula R(OH) n , wherein R is an aliphatic or cyclo-aliphatic group having from about 2 to 20 carbon atoms and n is at least 2; and at least one linear and/or branched acid which has a carbon number in the range between about C 4 to C 20 , wherein the synthetic ester composition has a hydroxyl number of between about greater than 5 to 180, preferably between about greater than 5 to 100, and more preferably between about 10 to 80. |
