The invention relates to compound gasoline. The compound gasoline comprises the following components in parts by weight: 70-100 parts of gasoline, 5-15 parts of ferrocene, 10-30 parts of xylene, 0.5-2 parts of butyl cellosolve and 8-16 parts of an antirust agent. The compound gasoline provided by the invention is likely to be fully combusted, is relatively high in combustion efficiency and fuel-saving, and reduces tail gas emission. The compound gasoline provided by the invention is simple in process formula, low in production cost and good in application effect, and popularization and application are facilitated.
