Abstract (en)
[origin: WO2007121205A2] A composition of a major amount of an oil of lubricating viscosity; a secondary or tertiary amine being represented by the formula R<SUP>1</SUP>R<SUP>2</SUP>NR<SUP>3</SUP> wherein R<SUP>1</SUP> and R<SUP>2</SUP> are alkyl groups of at least 6 carbon atoms and R<SUP>3</SUP> 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.
