A fuel composition includes a ring-hydrogenated alkyl furfuryl ether of the general formula (I): R″-TF-CH2-O—R or a mixture of the ethers, where TF represents a 2,5-disubstituted tetrahydrofuran ring, where each R independently represents a hydrocarbyl group having from 1 to 20 carbon atoms and where each R″ independently represents a methyl group, a hydroxymethyl group, the product of an aldol condensation reaction or an alkoxymethyl group of the general formula (II): —CH2-O—R′, where each R′ independently represents a hydrocarbyl group having from 1 to 20 carbon atoms, in combination with diesel fuels of petroleum origin or diesel fuels of bioorganic origin.
