The Short Answer
Your octane numbers and our octane numbers don't mean the same thing. From an engineering perspective the octane number is actually a kind of hilariously arbitrary number that basically boils down a bunch of different fuel qualities, that all both individually *and* collectively control a fuel's likelihood to knock, all into a single number, and because of that the precise testing for octane numbers changes depending on the body doing the regulation. So it would be entirely possible for two utterly identical batches of fuel to get different octane ratings when tested by different countries. However, our fuels are also slightly different, as Europe is going to have a slightly different set of additives than we get in the US, but that doesn't really account for most of the difference; the differing standards do.
