Abstract: The development of a fuel that is an alternative fuel to gasoline for internal combustion engines, which does not discharge toxic gases such as sulfur oxide that causes pollution, is low-pollution, and yet is highly efficient with a high output of power. An alternative fuel to gasoline including alcohol as the principal component, said alcohol comprising a mixed alcohol of 51˜60 percentage by weight of ethanol and/or methanol and isopropyl alcohol and isobutanol (mixing ratio: 9˜6:1.5˜0.5:2˜1), 20 plus or minus 5 percentage by weight of paraffinic hydrocarbon of five to eight carbon atoms, and 30 plus or minus 5 percentage by weight of toluene, maintaining an output equal to that of gasoline, yet without the need to be used with gasoline or reformed gasoline, and in addition decreasing the generation of toxic gases such as sulfur oxide and the like.
