Abstract
Abstract {PG,1 Load-carrying properties of gear oils are increased by the addition of triazole derivatives obtained by reacting benzotriazole or an alkylbenzotriazole with alkylphosphates, alkylphosphonates, or primary fatty amines, a naphthenyl oxazoline, or an alkenylsuccinyl mono- or bis-oxazoline.
