Abstract
Abstract Molybdenum-containing compositions prepared by reacting an olefinically unsaturated compound capable of reacting with active sulfur with a composition prepared by reacting: (a) a phosphorus-containing acid represented by the formula: ##STR1## wherein each X and X' is independently oxygen or sulfur, each n is zero or one and each R is independently the same or a different hydrocarbon-based radical; and (b) at least one hexavalent molybdenum oxide compound, and (c) hydrogen sulfide, in the presence of (d) a polar solvent are useful as additives for lubricants. Internal combustion engines, especially gasoline engines, when lubricated by said additive-containing lubricants exhibit improved fuel economy.
