An unleaded gasoline composition comprising: wherein Ris a linear alkenyl group containing 3 to 5 carbon atoms, optionally substituted by a methyl group, and Ris a linear or branched alkyl group containing 1 to 6 carbon atoms. The gasoline composition of the present invention exhibits good lubricity. The gasoline composition of the invention in another aspect provides increased sensitivity.

Gasoline compositions

A diesel fuel formulation containing a triethoxypropane and a palm oil methyl ester (POME), and a diesel fuel supplement containing a premix of a triethoxypropane and a POME is disclosed. The triethoxypropane may be 1,2,3-triethoxypropane or 1,1,3-triethoxypropane.

Diesel fuel formulation

A diesel fuel formulation with improved lubricity is provided containing (i) a fatty alcohol ester, (ii) an acid-based lubricity additive and (iii) an additional diesel fuel component. The ester (i) has the formula R1-C(O)&#x2014;O&#x2014;R2, in which R1 is for example either hydrogen or methyl and R2 is for example a C6 to C14 alkyl group.

Fuel formulations

Gasoline compositions are provided comprising component A, an alkyl alkenoate compound, or a mixture of alkyl alkenoate compounds, selected from compounds of formula I: wherein Ris a linear alkenyl group containing 3 to 5 carbon atoms, optionally substituted by a methyl group, and Ris a linear or branched alkyl group containing 1 to 6 carbon atoms, with the proviso that component A has a boiling point or boiling point range within the temperature range of from 90 to 200&#xb0; C., and at least one additional selected component.

A gasoline composition is provided containing:
