ABSTRACT:
A fluid having a mineral lubricating oil base and containing an oil soluble, saturated aliphatic or aromatic hydrocarbon ester having from 10 to 60 carbon atoms which, if desired, can be used in combination with an aliphatic alcohol of from 8 to 13 carbon atoms. The ester alone and ester-alcohol combination imparts to the fluid the property of swelling seals in automatic transmissions, power transmissions and rotary engines, and thereby improves retention of the fluid in these mechanical structures.
