Hi,
I'll be covering quite a large distance this summer, with a high proportion of motorway driving.
The car is rated for a minimum quality of E25, which is well below the E10, which is the minimum available in most of Europe, but the manual says that the engine also has "anti-knock control", which adjusts boost for different grades.
Normally I fill with standard 95 unleaded, as the price differential between 95 and 98 is quite high in Norway, but I see that this is almost 0 in some countries (according to https://autotraveler.ru/en/spravka/fuel-price-in-europe.html#.XPn-Q4gzZbd, 95 and 98 currently sell for almost the same price in the UK).
This being the case, is there a chance that the engine will be more efficient with higher octane fuel? If so, it might be cheaper to run in practice?
