Abstract
Hydrocracked lubricating oils are effectively stabilized against deterioration caused by light by the inclusion of at least one of certain dihydroxy components. Such component, e.g., 3,5-di-tert-butyl catechol and 4,6-di-tert-butyl resorcinol, provide outstanding inhibition to sunlight deterioration.
