Additives/Oxygenates
Asia-Pacific Economic Cooperation (APEC)

European Commission - Eurostat
Additives are non-hydrocarbon compounds added to or blended with a product to modify fuel properties (octane, cetane, cold properties, etc.):

oxygenates, such as alcohols (methanol, ethanol), ethers (such as MTBE (methyl tertiary butyl ether), ETBE (ethyl tertiary butyl ether), TAME (tertiary amyl methyl ether));
esters (e.g. rapeseed or dimethylester, etc.);
chemical compounds (such as TML, TEL and detergents).

Note: Quantities of additives/oxygenates (alcohols, ethers, esters and other chemical compounds) reported in this category should relate to the quantities destined for blending with fuels or for fuel use.

International Energy Agency (IEA)
Additives are non-hydrocarbon compounds added to or blended with a product to modify fuel properties (octane, cetane, cold properties, etc.):

oxygenates, such as alcohols (methanol, ethanol), ethers (such as MTBE (methyl tertiary butyl ether), ETBE (ethyl tertiary butyl ether), TAME (tertiary amyl methyl ether));
esters (e.g. rapeseed or dimethylester, etc.);
chemical compounds (such as TML, TEL and detergents).

Latin American Energy Organization (OLADE)
Additives/oxygenates includes alcohol which itself covers both ethanol (ethyl alcohol) and methanol (methyl alcohol) used as fuels.

Ethanol is a colorless liquid that can be produced by fermentation of plant materials with a high sugar content, such as sugarcane juice or molasses; plant materials with high starch content, such as cassava, corn, etc.; and materials with high cellulose content: firewood, plant wastes. It can be used as anhydrous or hydrated alcohol, alone or mixed with gasoline in internal combustion engines.

Methanol is also a colorless liquid that can be produced from several raw materials such as firewood, plant wastes, methane, natural gas, coal, etc. It is used in internal combustion engines.
