Fuel Labeling
Gasoline
The different types of gasoline are identified by a circle which inside appears a letter E and a number that defines each of the types. These numbers refer to the specific biocomponents in the gasoline:
E5: 5% biofuels (ethanol), equivalent to 95 octane gasoline
E10: 10% biofuels (ethanol), equivalent to 98 octane gasoline
E85: 85% bioethanol
Diesel
The different types of diesel are identified by a square in which a letter B appears followed by a number, as happens with the gasoline. In diesel fuels, however, we have a third variant that does not follow the guidelines mentioned. It is a square with the letters XTL inside:
B7: 7% biofuels
B10: 10% biofuels
XTL: paraffinic or synthetic diesel, not derived from petroleum
Alternative fuels
Identified with a diamond in which the composition of the gas used is mentioned inside:
LPG: Liquefied petroleum gas
CNG: Compressed natural gas
H2: Hydrogen
LNG: Liquefied natural gas
