    Abstract: An additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) 0.2 to 10 wt. % ashless friction modifier which is liquid at room temperature and pressure selected from (i) n-butylamine oleate or derivatives thereof, (ii) a substance comprising tall oil fatty acid or derivatives thereof, and (iii) mixtures of (i) and (ii); (b) 10 to 80 wt. % deposit inhibitor, and (c) carrier fluid. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated without the need for additional solubilising agent for the friction modifier, while containing sufficient friction modifier to achieve a significant benefit in fri loss, when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy.

    Abstract: There is disclosed a fuel lubricity additive, made by a two-step process wherein the first step is co-reacting an unsaturated base oil, predominantly from vegetable oil sources, and a compound having a diene structure and a carboxylic acid group, wherein the second step is esterifying or amidifying the free carboxylic acid group of anhydride group with a poly-hydroxy-containing compound or poly-amine compound to form the final fuel lubricity additive useful in diesel fuels. The inventive fuel lubricity additive also is useful as a dispersant.

    Abstract: The invention relates to combustion catalyst compositions which when blended into liquid hydrocarbon-base fuels reduce deposits in fuel combustion systems, inhibit corrosion in fuel systems and facilitate a more efficient oxidation of fuel. The combustion catalyst compositions comprise a surface-active/emulsifier agent, a lubricating oil and a liquid saturated hydrocarbon having the general formula C.sub.n H.sub.2n+2 wherein n is from 14 to 17.
