Alternative gasoline, diesel fuel, marine diesel fuel, jet fuel, and flexible fuel compositions are disclosed. The compositions include an alcohol and/or a glycerol ether or mixture of glycerol ethers, which can be derived from renewable resources. When combined with gasoline/ethanol blends, glycerol ethers can reduce the vapor pressure of ethanol and increase fuel economy. Added to diesel fuel/alcohol blends, glycerol ethers improve the cetane value of the blends. In jet fuel, glycerol ethers can replace all or part of conventional deicing additives, lowering skin toxicity, and glycerol ethers ability to reduce particulate emissions can lower the appearance of contrails. Used in marine diesel, the reduction in particulate emissions can be environmentally significant. In another embodiment, the alternative compositions comprise gasoline, ethanol, and n-butanol, and in one aspect, the ethanol and/or n-butanol can be derived from renewable resources. Fuel additive compositions, including glycerol ethers and hydrocarbons and/or alcohols, are also disclosed.
