More Information
Summary:The invention provides a method of highlighting the purity of a gasoline composition comprising a major amount of a substantially colourless gasoline having a Research Octane No. of at least 95, a Motor Octane No. of at least 85, density at 15 DEG C in the range 720 to 775 kg/m , sulphur content not greater than 50 mg/kg (ppmw), oxygenate content 0 to 15 % v/v contributing to oxygen content not greater than 2.7 % w/w, olefins content 0 to 18 % v/v, aromatics content 15 to 35 % v/v giving overall benzene content not greater than 1.0 % v/v, the balance of the gasoline being saturated hydrocarbon, which method comprises imparting a translucent blue hue to the gasoline composition by incorporating an effective concentration of blue dye therein; gasoline compositions comprising the substantially colourless gasoline and the blue dye incorporated therein; and a method of influencing motorists to use environmentally advantageous gasoline.
