ABSTRACT:
Substituted 1-aminonaphthalenes of formula I ##STR1## wherein n is 1-3, Ar is arylene, R.sub.1 and R.sub.2 are independently hydrogen, alkyl or phenyl, R.sub.3 is hydrogen, alkyl or substituted alkyl, and R.sub.4 and R.sub.5 have independently the same definitions as R.sub.3 or are independently aryl, substituted aryl or cycloalkyl, are effective stabilizers for lubricating oil or polymer compositions. The instant compounds are particularly effective in lubricating oil compositions when used with a diarylamine antioxidant.
