1. A method for formulating a fuel composition, which method comprises adding to a non-Fischer-Tropsch derived base fuel, from 0.5 to 5 mg/kg of a static dissipator additive which contains one or more active ingredients selected from the group consisting of sulphonic acids, polyamines, sulphones, and vinyl polymers, and an amount of Fischer-Tropsch derived fuel component having an electrical conductivity lower than that of the base fuel and static dissipator additive together, where the amount of Fischer-Tropsch derived fuel component is greater than the concentration c′, wherein c′ is defined by the equation:
X =A+c′(B−A)/100Wherein X is the target electrical conductivity for the product fuel composition, A is the electrical conductivity of the composition prior to incorporation of the Fischer-Tropsch derived fuel component and B is the electrical conductivity of the Fischer-Tropsch derived fuel component. |
