FIELD: chemistry.

SUBSTANCE: present invention relates to a package of additives for motor oil containing a detergent additive, ash-free nitrogen-containing dispersant, phenyl-α-naphthylamine, antioxidants and metal deactivator in form of a product of condensation of benzotriazole, formaldehyde and amine or tolutriazole derivative, wherein detergent additive contains highly alkaline colloidal dispersion of calcium carbonate, stabilised with alkyl salicylate and calcium sulphonate, as antioxidants - solution in oil of a mixture of amine salt of dialkylphenyl dithiophosphoric acid with zinc salt of dialkyldithiophosphoric acid, taken in ratio (1.5-1.7):1, alkylated diphenylamine and phenol antioxidant in following ratio of components, wt%: highly alkaline colloidal dispersion of calcium carbonate, stabilised with calcium alkyl salicylate calcium and calcium sulphonate 23.0-27.0; ash-free nitrogen-containing dispersant 18.0-22.0; phenyl-α-naphthylamine 9.0-11.0; solution in oil of mixture amine salt of dialkylphenyl dithiophosphoric acid with zinc salt of dialkyldithiophosphoric acid taken in ratio (1.5-1.7):1, 10.0-14.0; the alkylated diphenylamine 9.0-11.0; phenol antioxidant 1.0-10.0; product of condensation of benzotriazole, formaldehyde and amine or tolutriazole derivative - up to 100. Present invention also relates to motor oil.

EFFECT: technical result of present invention is improvement of quality characteristics of package of additives and improved operational characteristics of oil containing same, which is manifested in reduction of content of sulphate ash, phosphorus and sulphur with preservation of requirements for detergent, antioxidative and anti-aging properties of oil.
