FIELD: chemistry.
SUBSTANCE: present invention relates to a lubricant composition, and more particularly to a lubricant composition which contains an ethylene-alpha-olefin oligomer and an alkylated phosphonium compound. Lubricating composition according to this invention contains (per 100 wt. % of total lubricating composition): base oil in amount of up to 100 %; from 0.5 to 25 wt. % of liquid olefin copolymer and from 0.3 to 4.0 wt. % of alkylated phosphonium compound.
EFFECT: invention allows to reduce power consumption and increase resistance to negative factors, and thus this composition is suitable for use in reduction gear oil.
