A lubricant comprises, in weight per cent, 5-95 of one or more olefines <FORM:0988063/C4-C5/1> and 95-5 of one or more compounds Q-X-Z, wherein R is hydrogen or fluorine; R1 is hydrogen, fluorine, methyl, mono-, di-, or tr-fluoromethyl; R11 is a linear C7+ alkyl or fluoroalkyl radical; X is -O-; -S-, <FORM:0988063/C4-C5/2> Z is a linear C10+ alkyl or fluoroalkyl radical, and Q is a C1- 3 alkyl radical. A long list of suitable compounds is given. They can be used in emulsion form and can be mixed with mineral oils and their greases, di-ester, polyester, silicone and silicate ester oils. To form greases thickeners can be added, e.g. silica gel, carbon black, diatomaceous earth, graphite, molybdenum and tin sulphides, zinc, tin, lead, copper, alkali metal, alkaline earth metal soaps of fatty acids and particularly lithium stearate or hydroxystearate.
