Fuel for my new Macan 2.0 Petrol
BP 97 is the highest octane widely available in NI and I could never tell the difference between that and Supermarket juice when running my Golf R.
Macan SD Vocano Grey. LEDs, Pano Roof, PSE, Sports Chrono, PASM, Sports Design Mirrors, 21" Sports Classics in Black, lots of other extras.

I did use Sainsburys super unleaded in the Boxster untill some plank let the tank fill with water and i filled up with 40 litres of the stuff. They were at least gracious enough to pay the 3k+ bill to sort it all out, but have never trusted them since. Luckily there's a Maxol at the bottom of our road that keep super so I use that nowadays.

The better mpg you MAY get with the more expensive fuel will nowhere near compensate for the additional cost of the fuel though!!
Esso Super Plus, Total Excellium and BP Ultimate are 97 RON whereas Shell V-Power is 99. Tesco Momentum is also 99 RON but Tesco use more ethanol which may affect the calibration sensors that fine-tune the engine.
RON (Research Octane Number) is a guide to the acceleration behaviour of the engine whereas MON (Motor Octane Number) is a guide to high temperature, high speed operation of the engine (e.g. motorway cruising): RON is quoted at the pumps but MON is not. The specification for the MON is a maximum of 10 less than the RON (this is the "sensitivity") so would be a minimum of 85 for standard fuel, 87 for Esso, Total and BP, and 89 for Shell and Tesco. Pick your driving style and your typical journey and then pick your fuel.
Additionally (as Nuclear Nick reminded us in an earlier thread) octane number is only part of the equation "Additives perform many functions before, during and after combustion and are vital to maintaining performance, reliability and longevity. Additives are expensive and this is where the supermarkets trim their costs in order to maintain a margin on fuel sales."
You WILL get better performance and also mpg with the more expensive fuel, and you WILL get a cleaner engine over the lifetime of the car that MAY save you money in the long term. I accept this may not offset the higher cost of the fuel but, having paid a lot for the car, personally I'll not stint on maintaining it.
