Next year the Biospirit share is to be increased to 10%. I have seen a report about it on TV. Apparently old car engines are not tolerable with it. Then the affected drivers have to refuel Super Plus !!! I find this a mess. The old Opel engines, e.g. the X20XEV certainly do not tolerate this spirit or ?? So if my engine gets a damage by this stuff I will sue the state and the EU.
