Abstract

PURPOSE: A small amount of a specific amine is added to the base oil of lubricant to prevent strange noise of cylinder without any adverse effect on the characteristics as hydraulic oil.
CONSTITUTION: An amine of the formula (m=0, n=0 or m=2W3, n=1W6; R is 1W18C alkyl; R' is H, 1W18C alkyl), preferably octylamine, oleylpropylamine, etc., is added to the base oil of lubricant with ISO viscosity of 10W460 in an amount of 0.01W2, preferably 0.05W0.5wt%. When necessary, less than 30wt% of antioxidant and anticorrosive agent are added.
