Abstract (en)

A low-phosphorus lubricant comprises: an oil of lubricating viscosity; a nitrogen-containing and a nitrogen-free dispersant; a metal dihydrocarbyl dithiophosphate; and a hydrocarbyl-substituted carboxylic acid derivative, the ratio of the dispersants being such as to provide suitable fluoroelastomer seal compatibility.
