The fuel company can't claim more power though, only the car manufacturer can do that.
You will only see gains if your car is set up for 98ron.
This isn't snake oil, it isn't some myth, if the car is set up to take advantage of 98 ron you will see a drop off in performance and mpg if you run it on 95ron.
Your car will lose around 30hp if you run it with 95ron.
This is discussed at length on the German forums, mainly because they can get 102ron over there too, all the tests show that 102ron quietens the engine and smoothes it out more, but unless you have a custom map to take advantage of it (often sold by race tracks where custom maps can take advantage) there is not power or MPG gain, like the jump from 95 to 98 ron.
The confusing thing is often the UK websites don't say the car is set up for 98 ron.
My E350 is a good example, UK site says unleaded, German site says Super Benzin Plus (89ron).
So how do I know if my car is set up for 98 Ron?You will only see gains if your car is set up for 98ron.

Shell claim they do 2-engines-side-by-side long-term comparison bench tests that justify their claims.
Quite a few years ago at FoS BP had an opened engine that had been run for 20,000 miles on a dyno, rigged up with 2 cylinders on Ultimate and 2 on regular fuel. The 2 cyclinders running on ultimate looked much cleaner.bad company said:
Thanks. It would have been good to have known this from the start. Why on earth is not made clear by BMW uk?
It should say it on the inside of your fuel filler panel, 98ron then underneath 95ron minimum. Weirdly 98ron isn't available in the UK it's either 95, 97 or 99.

‘Engine can be run on 91 to 98 RON, quoted power and fuel consumption is based on 95 RON’
With regards 98 RON not being available, when Shell bought out their original high RON, it was 97 or 98. Now most high RON fuels are now 99, AFAIK.

That label seems similar to what my previous E36 petrol I-6 handbook said. It said something like..
‘Engine can be run on 91 to 98 RON, quoted power and fuel consumption is based on 95 RON’
With regards 98 RON not being available, when Shell bought out their original high RON, it was 97 or 98. Now most high RON fuels are now 99, AFAIK.
Nothing there or in the handbook to indicate that the car would run better on 98 RON.‘Engine can be run on 91 to 98 RON, quoted power and fuel consumption is based on 95 RON’

My F80 M3 says 98ron at the top and 95 as a minimum, the handbook states all performance data achieved with 98ron fuel, I would have though the 340i would be the same, but clearly not. Looks like it's not tuned for it but of course can run on it.

You'd have to be mad to run a modern turbocharged petrol car on the cheap crap. The improved economy of premium fuel pays for the additional outlay.
Even if it’s not tuned for the higher octane?You will get better mpg from using better fuel. This was true at least 10 years ago, I would have thought people would have cottoned on by now.

The handbook for my Superb 3.6 categorically states that you will see no power or economy benefits from using anything higher than 95 RON.
