Not long term, but when I worked West Coast of Scotland for 5 weeks straight there's not much choice for super up there. Had to rely on the old normal E5 unleaded and she ran fine tbh. Swapped straight back to super once home... Luckily never had to touch the new E10 yet... Would probably get a hire car instead if no options for super nowHas anyone used Asda petrol in the long term and have there been any problems attributed to it.
