Genuine curiosity here, not a rant. I notice a lot of you posting that you buy V Power or Super whatever petrol, but I can't see what you gain from it? By my understanding, your engine will either knock with a given fuel or it won't, and all modern petrol road cars are designed with 95 octane unleaded in mind because that's the "normal" fuel sold at petrol stations. So if it can use 95 without any problems, what do you gain from paying more for higher octane fuel? There's no efficiency savings, no power boost, just a lighter wallet.
Am I wrong?
