NOVELTY - Preparing environmentally-friendly gasoline additive comprises (i) taking solvent oil, 1,3,5,7-tetrakis(4-aminophenyl)adamantane, ascorbic acid, 5-aminotetrazole, organic nano material, graphene, glycerin polyoxyethylene ether, PPG-1 tridecanol polyether-6, polyetheramine and aromatic amine, (ii) adding solvent oil, 1,3,5,7-tetrakis(4-aminophenyl)adamantane, ascorbic acid, 5-amino tetrazole, organic nano material, graphene, glycerin polyoxyethylene ether, PPG-1 tridecanol polyether -6, polyether amine and aromatic amine into a reaction vessel, stirring, heating the reaction vessel, condensing and refluxing by the condenser, stirring for 3- 4 hours and allowing to stand for 5-8 hours, and (iii) adding additive into the gasoline, where the ratio of additive addition is 500-800 ppm. USE - The method is useful for preparing environmentally-friendly gasoline additive. ADVANTAGE - The method is environmentally-friendly, and improves the combustion effect of existing gasoline, reduces synergistic effect of gasoline corrosion and aging of parts and improves gasoline storage stability.
