Lubricating oil composition used in automatic gearboxes comprises a base oil, succinimide, fatty acid-amine condensation product, and dialkylhydrogen phosphite

摘要

Lubricating oil composition comprises a mineral or synthetic base oil having a kinematic viscosity of 1-30 mm<2>/s at 100 deg C and: (A) 0.1-0.5 wt.% of a non-boron-containing succinimide and a boron-containing succinimide; (B) 0.05-0.2 wt.% of a condensation product of a branched 8-30 C fatty acid and an amine; and (C) 0.1-1 wt.% dialkylhydrogen phosphite.
