This patent describes a method of reducing emissions from or increasing the utilizable energy of diesel fuel for powering internal combustion engines. It comprises: admixing with diesel fuel a fuel soluble organo-metallic fuel additive composition in an amount effective to supply from 0.01 to 1.0 parts per million of platinum per part of fuel. The composition comprising a compound having the general formula XPtR{sub 1}R{sub 2}, wherein X is a ligand containing at least one unsaturated carbon-to-carbon bond with an olefinic, acetylenic or aromatic pi bond configuration and R{sub 1} and R2 are, independently, benzyl, phenyl, nitrobenzyl or alkyl having from 1-10 carbons.
