Abstract: A fuel composition includes a lower alkyl monool(s) and C2-C6 esters of one or more long chain fatty acids. Generally, C, H and O atoms constitute at least 99.99% (by wt.) of the composition, and the composition can be essentially free of sulfur and/or nitrogen atoms. The composition can be provided by adjusting to less than 7.0 the pH of a liquid that contains at least one C2-C6 ester of one or more long chain fatty acids. The C2-C6 ester(s) can be provided by transesterifi-cation of a triglyceride-containing composition using a C2-C6 monool, which preferably is present in stoichiometric excess.
