Abstract
A lubricating composition is provided containing: a high viscosity synthetic hydrocarbon such as high viscosity polyalphaolefins, liquid hydrogenated polyisoprenes or ethylene-alphaolefin copolymers having a viscosity of 40-1000 centistokes at 100.degree. C.; a low viscosity synthetic hydrocarbon and/or optionally a low viscosity ester; and optionally an additive package to impart desirable performance properties to the composition.
Claims10
A lubricating composition comprising:
- (a) between 1 and 99 weight percent, based on the weight of components (a), (b) and (c), of a polyalphaolefin having a viscosity of between 40 and 1000 centistokes at 100.degree. C.;
- (b) between 0 and 99 weight percent, based on the weight of components (a), (b) and (c), of a synthetic hydrocarbon having a viscosity of between 1 and 10 centistokes at 100.degree. C.;
- (c) between 0 and 99 weight percent, based on the weight of components (a), (b) and (c), of a carboxylic acid ester having a viscosity of between 1 and 10 centistokes at 100.degree. C.;
- and
- (d) between 0 and 25 percent by weight of an additive package;
- wherein at least 1 weight percent, based on the weight of components (a), (b) and (c), of component (b) and/or (c) is present.
