I only ever run my XC60 Polestar Engineered on either Tesco Momentum or Shell V-Power (less so V-Power at the moment as its price seems to be really high compared to other Premium petrol for no real reason).
Both fuels are 99ron and have decent additives & cleaners over standard 95ron petrol meaning injector and other fuel system components will remain in better condition for longer.
I havent done a standard fuel to Premium fuel back to back comparison in the XC60 so cant really say what difference there would be performance & economy wise but in my previous cars that I have done comparisons, there definitely have been noticeable differences.
With the T6 & T8 being small capacity engine utilising multiple methods of forced induction (both a supercharger and Turbocharger), it should react much better to higher octane fuel than more conventional petrol engines.

Thanks. My last petrol car was a Brabus Smart Car (I have been using smartMAC as a user name since
) and I did notice a slight improvement in economy but hard to tell.
My issue was the expense of V Power in spain which is 30% more expensive than regular unleaded.
