In accordance with the present invention, it has been discovered that an additive which is substantially insoluble in, has low solubility in and/or is otherwise incompatible with a functional fluid, may be supplied to the functional fluid by use of a gel composition and/or a solid additive composition containing the additive, such that the functional fluid can receive the benefit of the supplied additive and/or contain levels of the additive not otherwise achievable by conventional delivery method due to the incompatibility of the additive with the functional fluid.

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.
