<p>The present invention as disclosed provides a multipurpose additive for a hydrocarbon fuel, a lubricating oil, or a mixture of a hydrocarbon fuel and a lubricating oil, comprising the reaction product of (a) a glycidyl ether compound of the formula where R2 is a benzene ring having attached thereto at least one aliphatic hydrocarbon motor fuelor lubricating oil solubilizing group having at least 8 carbon atoms, and (b) an amine having at least one amino group having at least one active hydrogen atom. Also disclosed are compositions comprising (1) a major proportion of a hydrocarbon fuel such as,for example, gasoline, a lubricating oil, or a mixture of a hydrocarbon fuel and a lubricating oil; and (2) a minor amount,e.g. about 20 to 60 p.p.m., of the above-mentioned multipurpose additive. The novel multipurpose additive is useful as a carburator detergent and combustion chamber detergent, and in addition, provides effective rust inhibition when used in automotive gasoline fuels at low concentrations.</p> |
