The invention relates to the technical field of gasoline additives, and particularly provides a preparation method and application of a compound gasoline antiknock agent and gasoline. The compound gasoline antiknock agent is prepared from the following components in parts by mass: 5 to 10 parts of methyl tert-butyl ether, 10 to 45 parts of p-methoxyaniline, 10 to 30 parts of butyl oleate and 1 to 3 parts of polyethylene glycol. Compared with the prior art, the compound gasoline antiknock agent disclosed by the invention has the advantages that the commercial value of gasoline is further improved and more economic benefits are created for enterprises by virtue of the synergistic effect of all the components and the property of greatly improving the octane number and antiknock index of the gasoline. 本发明涉及汽油添加剂技术领域，具体提供了一种复配汽油抗爆剂的制备方法及其应用、汽油。该复配汽油抗爆剂按质量份计，包括以下组分：甲基叔丁基醚5～10份，对甲氧基苯胺10～45份，油酸丁酯10～30份，聚乙二醇1～3份。与现有技术相比，本发明的复配汽油抗爆剂通过各组分的协同作用，通过大幅提高汽油的辛烷值和抗爆指数的性质，进一步提高汽油的商业价值，为企业创造更多的经济效益。
