FIELD: chemistry.
SUBSTANCE: invention relates to a grease lubricant composition containing a thickener and base oil produced via Fischer-Tropsch synthesis, in which said base oil has kinematic viscosity at 100°C of 8-30 mm2/s, the thickener contains soap and content of thickener in the grease lubricant composition is equal to or higher than 10 wt %. The present invention also relates to use of base oil produced via Fischer-Tropsch synthesis in a grease lubricant composition to improve anti-wear properties of the composition, use of base oil produced via Fischer-Tropsch synthesis in a grease lubricant composition to improve corrosion coefficient of copper and use of base oil produced via Fischer-Tropsch synthesis in a grease lubricant composition to reduce concentration of additive in the composition.
EFFECT: obtaining grease lubricant with defined characteristics, specifically good resistance to mechanical action, oil separating, good resistance to oxidation and good anti-wear properties.
