FIELD: lubricants. SUBSTANCE: additives for SF/CC and CD/SF (API classification) motor oils are prepared by consecutively adding to the first oil-diluent portion, at 40- 75 C and stirring, high-alkalinity calcium phenate, polyalkenylsuccinimide, and zinc dialkyl dithiophosphate, after which the second oil-diluent portion, highalkalinity calcium sulfonate, and ash-free phenol antioxidant are added. Additive complex contains, wt %: high-alkalinity calcium phenate 10-30, polyalkenylsuccinimide 20-40, zinc dialkyl dithiophosphate 20-30, highalkalinity calcium sulfonate 10-15, ashless phenol antioxidant 5-7, and mineral oil-diluent - the balance. Weight ratio of polyalkenylsuccinimide to zinc dialkyl dithiophosphate in the additive complex must be such that nitrogen-tozinc atomic ratio were 0.35-0.9, whereas weight ratio of high-alkalinity calcium sulfonate to ashless phenol antioxidant is (2-2.2): 1. EFFECT: improved working characteristics of motor oils. 3 cl, 5 tbl
