Abstract
Hydrocracked lubricating oils are effectively stabilized against deterioration caused by light by the inclusion of at least one of certain dihydroxy-diphenyl components. Such components, e.g., 4,4'-bis(2,6-di-tertiary butyl phenol), provide outstanding inhibition to sunlight deterioration.
