ABSTRACT:
Synthetic ester lubricant blends are described which contain 1-90 weight percent of an N-substituted polyoxyalkylene phenothiazine. The polyoxyalkylene group can be derived from ethylene, propylene, butylene or styrene oxides. The blends have superior oxidative and thermal stability and at the same time have good viscosity characteristics and pour points over a wide range of temperatures.
