FIELD: lubricants.
SUBSTANCE: lubricant compositions based on base oils. A lubricant composition contains a base oil in the form of a synthetic oil or mineral oil, which is a polyalkylene glycol base oil, or a synthetic base oil in the form of polyalphaolefins, or a mineral hydrocracked base oil, a copper salt and a carboxylic acid (C15-C18), diphenylamine, oleic acid and a succinimide derivative in the form of commercial additives - C-5A, or C-5AB, or C-1500B, or C-2500 in the following ratio, wt.%: base oil 97.3-97.8; salt of copper and carboxylic acid (С15-С18) 0.06-0.27, diphenylamine 0.33-0.945, succinimide derivative 0.99-1.755, oleic acid 0.11-0.405.
EFFECT: elimination of clogging of the oil channels of the lubrication system of internal combustion engines, as well as improvement of anti-wear and detergent properties.
