Abstract
A low temperature lubricant oil composition having improved viscosity-temperature properties, lubricating properties and pour point is described. The composition comprises a homogeneous mixture of from 1% to 50% by weight of poly(dimethylsiloxane) having an average viscosity at 100.degree. F between 100,000 cs and 1,000,000 cs, the remainder of the mixture being a hydrocarbon oil selected from certain alkenes, isoparaffins and naphthenics. The composition can also contain a foam inhibitor such as a perfluoroalkylpolyether.
