The invention discloses a gasoline additive for an environmental protection and energy-saving vehicle. The gasoline additive comprises the following components in parts by weight: 12-18 parts of nitromethane, 5-8 parts of boron, 2-5 parts of pyridine, 6-8 parts of didodecyldimethylammonium, 3-6 parts of carbon fluoride, 1-3 parts of magnesium perchlorate, 2-4 of BHT (butylated hydroxytoluene), 1-3 parts of light calcium carbonate, 4-7 parts of dimethyl acetal, 4-7 parts of 3-methyl-1-butylene, 16-21 parts of methyl tert-butyl ether, 6-9 parts of 2,2,3-triptane, 1-3 parts of cerium oxide, 1-3 parts of beryllium carbide, 5-8 parts of N,N-dimethylaniline and 2-4 parts of amino acid palladium complex. The additive can effectively improve the gasoline quality, increase the gasoline octane number, enhance the fire performance of fuels, can be completely burned together with the fuels without generating precipitation or residues, reduce the tail gas exhaust pollution of motor vehicles, reduce the running cost of the motor vehicles, and has the obvious oil saving effect.
