Hello, I expect a Seat Leon St Cupra 300 4drive (non-binding delivery in October). According to Seat, the power and consumption data refer to Super Plus, but you can also refuel normal super gasoline (E10) if you have low power input (source: brochure). I have a few questions that you might be able to help me with: 1. Is there a lasting influence on the engine when driving with super gasoline? 2. Is super gasoline more or less used with super gasoline? Is there anything special about this topic during the start phase (1500km)? 4. What are your experiences with Super/Super Plus in the Cupra? Thank you in advance!
