NOVELTY - A methanol gasoline additive contains toluene, xylene, pentane derivative, heptane derivative, isobutyl alcohol, isopropyl alcohol, isopentanol, ethanol, ethylene glycol, anti-freeze agent, 2,6-tert.-butyl-p-cresol antioxidant and anti-glue agent, N,N-disalicylidene-1,2-propylenediamine metal deactivators, polyisobutylene amide isooctyl, calcium petroleum sulfonate, detergent dispersant, benzotriazol file, dimerized linoleic acid, sodium nitrite, preservative, alkyl polyglycoside, methyl tert,-butyl ether, triethanolamine oleate soap, petroleum sulfonate, and composite emulsifying surfactant.    USE - A methanol gasoline additive (claimed).    ADVANTAGE - The methanol gasoline additive is convenient to use, dynamically stable, suitable for low temperature and different seasons, does not produce vapor lock, ensures normal engine, combustion, and start-up performance, and has low sulfur-nitrogen content, low air resistance, and high corrosion resistance.
