This invention relates to the use of esters with low water solubility as oxygenates in gasoline fuels. This invention relates to a gasoline fuel, comprising an ester and butane, wherein the ester contains 5 to 14 carbon atoms. This invention also relates to using a low water solubility ester as an oxygenate in automotive gasoline used in internal combustion engines. Additionally, the invention provides a gasoline fuel, comprising an ester, wherein the ester has a water solubility of less than about 15,000 mg/L at 20 °C, preferably less than about 6,500 mg/L at 20 °C and the fuel has an overall water solubility of less than about 5,000 mg/L at 20 °C. |
