Abstract
Homogeneous lubricant blends are disclosed comprising polyether liquid lubricants miscible with synthetic hydrocarbon fluids or severely hydroprocessed basestock. The lubricants comprise SHF or hydroprocessed basestock and polyalkylene oxide polymer having recurring units of at least one long chain monoepoxy alkane monomer(s) containing 8 to 30 carbon atoms and short chain comonomer(s) selected from the group consisting of substituted or unsubstituted tetrahydrofuran, oxetan, butylene oxide propylene oxide and ethylene oxide wherein the mole ratio of long chain monoepoxy alkane monomers to short chain comonomers is between 0.5 and 9.
