Today I read in the news that the biofuel with 10% ethanol (E10) will reach the tanks at the end of the year. According to the list, all smarts are suitable! – But what does the legal situation look like when something breaks!? – And how does that affect consumption? Rather negative. – Will this fuel be cheaper if consumption increases? – Can one change back and forth between the super sprite varieties without hesitation? What do you think about it?http://www.dat.de/products/products_printed/e10.page
