Beschreibung
Zusammenfassung:	FIELD: petroleum refining and petrochemistry, more particularly motor oil intended for use in highly augmented automobile diesel engines. SUBSTANCE: the claimed motor oil comprises, wt.%: calcium sulfonate, 2.0-4.5; zinc dialkyl dithiophosphate, 0.6-1.2; polymer detergent additive, 1.5-4.5; sulfurized alkaline calcium alkyl phenolate, 2.5-5.5; zinc dialkyl dithiophosfate, 1.1-2.2; and mineral oil, up to 100. Polymer detergent additive includes product of reaction of alkyl phenols with molecular weight of 900-1500, polyethylene polyamines with 3-6 amine groups and formaldehyde modified with boric acid and aliphatic monocarboxylic acid which contains 10-20 carbon atoms, or diethylene triamine alkenyl succinimide modified with phthalic or maleic anhydride. The present invention allows for safe engine operation and increased service life of oil. EFFECT: improved properties of the motor oil. 3 cl, 4 tbl
