A method and results of tests is resulted on the machines of friction of CHSHM and SMC-2 of butter of I-G-A-32, applied in hydraulic actuators of build and travelling machines as a working liquid. It is rotined that a value is minimum the necessary concentration of the antiwear additive of Infineum S9425 artificially entered in butter must make no less than 0,45%, that provides the least wear of the ground pair during work them in the modes of the mixed and border friction.
