FIELD: chemistry.
SUBSTANCE: present invention relates to a lubricating composition containing: a) the base oil mixture, which contains: distillate naphthenic base oil, having the content of saturated hydrocarbons, measured according to the IP368 standard, higher than 92% and containing less than 10 ppm sulphur; and base oil obtained via Fischer-Tropsch synthesis. The ratio of the weight of the distillate naphthenic base oil to the weight of the base oil obtained via Fischer-Tropsch synthesis is in the range of 10:90 to 50:50; b) naphthenic high-viscosity cylinder base oil in the amount of 1 wt % to 20 wt % with respect to the total weight of the composition; and c) one or more additives. The total amount of the base oil added to the lubricating composition is in the range of 50 to 99.9 wt % with respect to the total weight of the lubricating composition. The present invention also relates to the use of the lubricating composition (versions).
EFFECT: obtaining the lubricating composition which provides the improved detergent power and improved engine cleanness.
