E10 - more bio-fuel in petrol
What you must bear in mind. On this page, you will be given valuable tips for using the new fuel E10.
Questions and answers about the new fuel E10
What does the abbreviation "E10" stand for?
"E" stands for ethanol or the bioethanol content of a fuel. The number "10" stands for the percentage of these components. Bioethanol is obtained from plants that are grown on an environmentally-friendly basis.
Why does E10 exist?
In Germany, an EU guideline is implemented, according to which the bio-fuel content, across all types of fuel, is to rise to ten per cent by 2020 and make a contribution to the reduction of CO2 emissions. In parallel to this, statutory compulsory certification for sustainable bio-fuels is to come into effect from next year. The aim of this is that only sustainably produced bio-components will continue to be used.
Who can fill up with E10?
About 90% of all cars fuelled by petrol take E10, according to the Federal Ministry for the Environment. New vehicles are generally suitable for E10.
You can find out whether your vehicle takes E10 from your vehicle manufacturer. You can also find a list of E10-compatible vehicles on the website of Deutsche Autombil Treuhand GmbH at www.dat.de. Before filling your vehicle up with E10 for the first time, you must make sure that it takes E10.
Why don't all vehicles take E10?
Ethanol has different chemical properties to petrol. This may, especially in mixtures with fuel, have an impact on sealing compounds (elastomers) and the metal components used in the fuel system. Studies have shown than ethanol can corrode aluminium. This may lead to leakages in the fuel system, with the risk that fuel leaking on hot parts (turbo charger, exhaust pipe etc.) will ignite, causing serious damage.
What consequences does misfuelling in unsuitable vehicles have?
Studies have shown that, in unfavourable conditions, damage cannot be ruled out in the case of a one-off misfuelling. In such cases, there may be leakages in the fuel system, which may, in an extreme case, even lead to the risk of a vehicle fire. In the event of misfuelling with E10, it is imperative that the vehicle is transported to a garage and the unsuitable fuel pumped out.
Is E10 also imported to other countries in Europe?
As things currently stand, no other EU country, apart from Germany and France, is planning to import E10. The other countries will probably wait for the amendment to the European Standard EN228. This is to be passed in the first quarter of 2012.
Is something also changing in the admixture of bio-components in diesel fuels?
No, nothing is changing here.
