Today, nearly all petrol sold in Sweden contains 5 per cent ethanol. As early as 1997, OKQ8 began blending 10 per cent ethanol into its petrol. In 2000, uniform regulations on petrol within the EU came into effect and the ethanol content of OKQ8’s fuel was subsequently reduced to the current 5 per cent, in line with the official specifications for the make-up of fuels that can be called petrol. However, efforts are currently under way within the EU to approve a 10 per cent blend of ethanol as allowable under the specifications for fuels labelled as petrol. Blending up to 10% ethanol into petrol fuel does not affect the motor and is acceptable to the majority of car manufacturers. Aside from a reduced dependence on petrol, low-blending has advantages for the environment.
Bioethanol is a renewable fuel – something which is its most important characteristic in terms of nature’s cycle. The positive environmental effects are, of course, relatively limited in the case of a 5 per cent ethanol blend. Even so, a petrol-ethanol fuel blend does provide a somewhat better emission value than that of pure petrol.
