A composition of a major amount of an oil of lubricating viscosity; a secondary or tertiary amine being represented by the formula R 1 R 2 NR 3 wherein R 1 and R 2 are alkyl groups of at least 6 carbon atoms and R 3 is hydrogen, a hydrocarbyl group, a hydroxyl-containing alkyl group, or an amine-containing alkyl group; and a dispersant, provides high static coefficients of friction and a durable positive slope during oxidative and mechanical stressing, particularly as a friction component of an automatic transmission. |
