Internal engine lubricating oil |
| abstract |
FIELD: preparation of lubricating agents. SUBSTANCE: lubricating oil includes 2-15 % by weight of the reaction product of polyisobutylene-succinic acid having 1.3-4 succinic groups per equivalent weight of polyisobutylene that has an average molecular weight of 1300-5000 and the ratio of number-average-to average molecular weight of 1.5-4.5, with 1 equivalent of polyisobutylene-succinic acid being added to the reaction together with 0.7-0.95 equivalent of polyamine; 0.01-2.00 % by weight of a basic alkali metal sulfonate or carboxylate; and mineral oil or additive oils up to 100 % balance. EFFECT: improved quality. 3 cl, 11 tbl |
