ABSTRACT:
An improved synthetic ester lubricant base stock formed by reacting at least one of trimethylolpropane and monopentaerythritol with a mixture of aliphatic monocarboxylic acids is provided. The mixture of acids including straight-chain acids having from 5 to 10 carbon atoms and an iso-acid having from 6 to 10 carbon atoms, preferably iso-nonanoic acid. The base stock is mixed with a conventional ester lubricant additive package to form a lubricant having a viscosity at 210.degree. F. of at leasts 5.0 centistokes and pour point of at least as low as -65.degree. F. The resulting lubricants have a decreased tendency to form deposits in gas turbine engines.
