Abstract (en)
A lead-free high performance gasoline whose characteristics are within the extent of the standards for racing car gasoline and which can easily cope with annual slight changes in the standards. Particularly, this invention provides a lead-free high performance gasoline which contains (1) toluene in an amount of from 50 to 70% by volume, n-heptane in an amount of from 2 to 10% by volume, isopentane in an amount of from 5 to 25% by volume and, if necessary, direct distillation light naphtha in an amount of from 10 to 30% by volume and a C4 fraction of distillate in an amount of from 2 to 5% by volume or (2) toluene in an amount of from 45 to 60% by volume, methyl-tert-butyl ether in an amount of from 10 to 20% by volume, n-heptane in an amount of from 10 to 20% by volume, isopentane in an amount of from 5 to 15% by volume and a C4 fraction of distillate in an amount of from 2 to 5% by volume, wherein the lead-free high performance gasoline satisfies the conditions of: density at 15 DEG C </= 0.81 g/cm<3>; 97 < research octane number </= 101; and Reid vapor pressure >/= 0.4 kg/cm<2>. By changing blending ratio of each component in the above composition (1) or (2) within the above range, the gasoline of this invention can easily cope with annual changes in the fuel standards for rallies and races without reducing output characteristics.
