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 fuel formulation containing (i) tricyclene, which is suitably biologically derived, and (ii) a gasoline base fuel. The formulation may contain one or more additional biofuel components or oxygenates: it may for example include ethanol, or ethanol together with one or more additional biofuels. The invention also provides a method for preparing the formulation, its use in a spark ignition engine, and the use of tricyclene in a gasoline fuel formulation for various purposes, including to enhance lubricity.
