AutoGas or LPG (Liquid Petroleum Gas) is the most commonly used alternative fuel for automotive vehicles.

There are currently 25 million vehicles fuelled using LPG, of which 15 million are in the European Union. They account for next to 55,000 vehicles in Spain.

The 70s price crisis caused the initial drive behind the development of alternative automotive fuels, when countries sought to reduce their dependence on crude oil imports. Concern for pollution in major cities has put pressure on the governments to replace conventional products with cleaner ones. As a result, the governments seek fuels that emit fewer of the solid particles that cause environmental pollution and less carbon dioxide (CO2) and nitrogen oxides (NOx), the main elements related to the greenhouse effect.

In many countries, AutoGas has become the most important fuel thanks to its inherent advantages and impressive environmental benefits in comparison with petrol, diesel and others.
