Abstract
The present invention discloses additive package comprising a mixture of (a) 6-10% by weight of fatty acid (b) 7-15% by weight of alkoxy ether and (c) 60-85% by weight of linear or branched chain monohydroxylated aliphatic saturated alcohol (C2-C8) for improving stability of mixtures of methanol-gasoline, ethanol-gasoline blends containing at least 5-15% by volume of short chain alkanol (methanol/ethanol). The additive composition is added to the alcohol-gasoline blends to improve low temperature stability, provides corrosion protection and to normalize vapor pressure of methanol/ethanol-gasoline blends.
