Which UK fuel has no ethanol? Esso super Esso super unleaded petrol (Synergy Supreme+ Unleaded 97 and Synergy Supreme+ 99 ) is ethanol free (Except in Devon, Cornwall, North Wales, North England and Scotland). https://www.esso.co.uk/en-gb/fuels-faqs Seems like Devon and Cornwall should become 1 UK country instead of an independent Cornwall - but that's up to the people of England since it's England, but, what if you drive out there on fuel purchased in Wiltshire maybe that doesn't have ethanol? Is it a law, is it a thing?
