Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
The increased solubility of water with higher ethanol content permits E30 and hydrated ethanol to be put in the same tank since any combination of them always results in a single phase. Somewhat less water is tolerated at lower temperatures. For E10 it is about 0.5% v/v at 21 °C and decreases to about 0.23% v/v at −34 °C. [30]
The 3-carbon alcohol, propanol (C 3 H 7 OH), is not often used as a direct fuel source for petrol engines (unlike ethanol, methanol and butanol), with most being directed into use as a solvent. However, it is used as a source of hydrogen in some types of fuel cell; it can generate a higher voltage than methanol, which is the fuel of choice for ...
Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline.

Ethanol (data page) provides detailed information about the chemical properties, physical properties, and safety measures of ethanol.
The Food and Drug Administration (FDA) has revoked the use of Red Dye No. 3 (also known as erythrosine, Red Dye 3, FD&C Red No. 3 and Red No. 3) in food and ingested drugs as of January 15, ...
[87] [88] Several countries in the Caribbean Basin imported and reprocessed Brazilian ethanol, usually converting hydrated ethanol into anhydrous ethanol, for re-export to the United States. They avoided the 2.5% duty and the tariff, thanks to the Caribbean Basin Initiative (CBI) and free trade agreements. This process was limited to 7% of U.S ...
