Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: composition of additives for lubricating oil contains sulphur-containing organic compounds and 0.06-0.14 wt % mixture of 2,5-diheptyl-3,4-fullero [60]tetrahydrothiophene-1-oxides of formula (1), where n=1(50%), n=2(30%), n=3(15%), n=4(5%). The sulphur-containing additives used are DF-11, OTP, sulphided C18-C26 -olefins. ^ EFFECT: improved anti-wear and antiscoring properties. ^ 1 tbl, 5 ex Сущность: композиция присадок к смазочным маслам включает серусодержащие органические соединения и 0,06-0,14% мас. смеси 2,5-дигептил-3,4-фуллеро[60]тетрагидротиофен-1-оксидов формулы (1). В качестве серусодержащих присадок используют ДФ-11, ОТП, сульфидированные α-олефины фракции С18-С26. Технический результат - повышение противоизносных и противозадирных свойств. 1 табл. ! ! где n=1 (50%), n=2 (30%), n=3 (15%), n=4 (5%)
