(un)branched 1-20C alkyl gps., and/or (b) poly-alpha-olefins and additives. The additives used are (1) one or more organic phosphates of formula R1-O-P(=O)(-O-R2)(-O-R3) in which R1, R2 and R3 are alkyl, aryl or alkylaryl having 1-15C atoms, in amt. of 0.01-10%, based on the total wt. of the lubricant (2) one or more organic phosphites of formula R1-O-P(-O-R2)(-O-R3) in which R1, R2 and R3 are as above, in amt. of 0.001-1%, based on the total wt. of the lubricant and (3) one or more organic or halogenorganic silicones in amt. of 0-100 mg, based on 1 kg total wt. of the lubricant.
