E10 - fuel for climate protection and secure energy supply
E10 has been offered as a new grade of automotive fuel at German filling stations since 2011. It is the designation for petrol fuel that can contain up to 10 vol.-% of bioethanol. "E" stands for ethanol and the number "10" for the bioethanol content in the fuel.
In Europe, E10 is available in Germany, France, Finland and Belgium. In the US, however, it has been available since the 1970s and it is the standard petrol today.
Advantages of E10
Bioethanol in E10 substitutes fossil fuel and therefore it makes an important contribution towards reducing CO2 emissions in the transport sector. It reduces greenhouse gas emissions by more than 70% compared to fossil fuels and its production is based on renewable agricultural raw materials grown sustainably here, in Europe. CO2 savings and sustainable production are regularly examined by independent experts according to a governmentally approved certification system.
The bulk of the bioethanol used for blending in Germany is produced in the EU. Thereby they reduce the dependence on imported energy and at the same strengthen rural structures by creating a new domestic branch of industry.
Conflicting statements about the suitability of E10 for certain types of vehicles have led to confusion among customers. According to the ADAC, the German Automobile Association, auto manufacturers have issued clearances for E10 for over 90% of the petrol engine vehicles in Germany, i.e. these vehicles can run on E10. Newer models can even be powered with E20, petrol with an ethanol content of up to 20%. Lists for all makes of vehicle showing the models that can run on E10 can be obtained from the ADAC or from Deutscher Automobil Treuhand.
The bioethanol blended in E10 has a lower energy content than petrol. However, scientific studies show that E10 does not increase fuel consumption to any appreciable extent. According to Prof. Dr. Bernhard Geringer of the Technical University of Vienna, the maximum increase in consumption versus conventional premium grade petrol is 1.9%.
