Skoda Slavia: will higher-octane XP95 fuel improve efficiency and performance?

I’m looking at buying the Skoda Slavia 1.5 DSG. Does it need only XP95 petrol or can regular petrol be used?

Autocar India says: The Slavia 1.5 TSI can run on regular petrol, but it won’t deliver the same level of performance and efficiency as it would with XP95, which has a higher octane rating. Given that the 1.5 TSI engine features a high compression ratio, using higher-octane XP95 fuel will help it extract the best performance, smoothen the throttle response and, potentially, better its fuel efficiency.

While regular petrol won’t harm the engine, you may notice a slight drop in power and efficiency. If XP95 is not easily available, you can safely mix it with regular petrol. Given the performance benefits, the cost of XP95 – around Rs 5 more per litre – is a worthwhile investment for an engine designed to perform best with it.
