Answer 1

You’re comparing apples to oranges. The octane ratings aren’t calculated the same way so you can’t make a direct comparison. The way it’s calculated in Europe leads to a higher number on paper, but it’s the same old gas used in N/A.

It’s like asking ‘why does Canada get 4L jugs of milk but in the US we just have 1 gallon?’ It’s more or less the same, just a different measuring system.
