we dont get leaded fuel in the uk thay stoped selling it 15-20 years ago
difference between unleaded and super unleaded is the ron or octane rating, the higher the ron the hotter and cleaner the fuel burns
unleaded is 93-95 ron
super unleaded is 97-99 ron
and in the uk we can get 105 ron whats designed for performance cars but not sold at all petrol stations
i tend to run my corsa on super or premium unleaded as it makes the car feel more responsive
