Vehicle fuel oil environmentally-friendly and energy-saving agent

The invention discloses a vehicle fuel oil environmentally-friendly and energy-saving agent which comprises the following components in parts by weight: 10-12 parts of solvent oil; 8-10 parts of oil calcium sulfonate; 5-7 parts of ethyl acetate; 5-6 parts of C9 alkylphenol polyoxyethylene ether; 10-15 parts of isooctyl nitrate; 15-17 parts of sulfonated fatty acid isooctyl sodium salt; 10-15 parts of naphthenate; 8-12 parts of diesel/petrol; 15-17 parts of sodium bis-(2-ethylhexyl) sulfosuccinate, 3-5 parts of dicyclopentadiene; and 3-5 parts of succinimide. The environmentally-friendly and energy-saving agent can improve the vehicle dynamic property, reduce the oil consumption and the vehicle operation cost and also reduce the emission of pollutants in motor vehicle waste gas, effectively improve the gasoline quality, gasoline octane number and the flammability, and completely combust along with the fuel without generating sediments or residues and has oil saving ratio, no side effects and no adverse effects on other properties of fuel oil.
