ABSTRACT:
Lubricants having a Brookfield viscosity at -40.degree. C. equal to or below 20,000 cP (preferably 15,000 or less) are formed from blends composed of a major amount of mineral oil in the range of about 90N to about 140N; and minor amounts of poly-.alpha.-olefin oligomer (PAO) formed from 1-alkene of 6 to 20 carbon atoms and having a kinematic viscosity of about 2 cSt at 100.degree. C.; and vinylaromatic-maleic ester polymeric viscosity index improver. Synergistic low temperature viscometric properties are exhibited by typical compositions of this type.
