Abstract

A method for improving the color stability of lubricating oils, especially of a light petroleum base lubricating oil, which has had a hydrofinishing treatment, characterized in that it consists in incorporating a small enough quantity in the oil to improve the color stability of the oil, of a tetraalkylthiuramyl sulfide mono of the formula ** (See formula) ** where the Rs represent alkyl or cycloalkyl groups having from 1 to 12 carbon atoms.
