100 Octane Petrol in N54

Well, then guess what? Ferrari’s and Porsche’s #1 market is America. I don’t have sales figures and the following is pulled out of my fat arse, but I bet California is their flagship market. It is after all the 7th largest economy in the world. And in the San Francisco Bay Area and Silicon Valley, with so many folk with far more money than sense, you cannot swing a dead cat without hitting a Ferrari or a Porsche. It’s an embarrassment of riches. (But then my home country is even worse.)

And everybody runs on s**t fuel. Sure, all tuned accordingly. But not a single owner complains about performance. Zero. Full stop. They complain about ‘performance awards’, but that’s another story.

He who cannot find happiness with a 300bhp street car … is not a very happy bloke.

That’s all I have to say.

There is a difference between "complains [sic] about performance" and the simple fact that should they be run and mapped for better fuel they would run and perform better on better fuel.
You have a bunch of bananas and give one to a monkey its going to be happy it got a banana if it doesnt know there is a whole bunch

Im not sure why you're trying to argue here, we actually agree, if your car isnt tuned for premium fuel its not going to make a bit of difference.

If your vehicle isn’t tuned for 100 octane, it won’t do anything. My track car and bike are not tuned for 100 octane. I’ve never felt fuel was the winning/losing factor.

BUT if you have a car mapped for 99RON or 100OCT (which is frequently the case here with tuned/enthusiast cars) if you run that car on 95 believe me you know that its on 95.
