Quotation: Directive 2009/30/EC of the European Parliament obliges all Member States to market petrol with a maximum of 10 % by volume fuel ethanol (bioethanol) under the industry abbreviation E10 (of ethanol 10%), thereby reducing dependence on the oil-producing countries. According to the EU Directive, for vehicles which do not tolerate this type E10, the existing petrol as a so-called conservation site must continue to be offered at least until 2013 After that, only the petrol type Super Plus will be available for the vehicles that do not tolerate the fuel with 10% ethanol. Diesel vehicles are not affected by the change. So it is in Wikipedia. Now, however, I read in the local press that car manufacturers from other European countries do not align their vehicles at all to E10, even warn against refueling this fuel when visiting Germany. Does anyone know more about this? Is E10 again a German (tube-creep) drive, similar to the exhaust badges, whose effectiveness today is proven to tend towards zero? Many greetings, Markus.
